Abstract and Figures

The present investigation was undertaken with 25 genotypes of bottle gourd for evaluating their performance for various horticultural characters. The genotype Sarika was found to possess maximum number of primary branches, while, Anand Bottlegourd-1 recorded maximum vine length. The cultivar Thar Samridhi was noted for maximum number of leaves and thicker flesh and the genotype NBBL-12 was noted for earliness to flowering and fruiting. The genotype Gaja was found to be superior and promising for lower sex ratio (male to female), more number of fruits per vine, higher fruit yield and seed yield per hectare. Performance studies revealed that the genotypes Gaja, NS-421, NBBL-12, Sharada, INDAM-204, NS-443, Super Dhana, Arka Bahar and Krushi Sampada were found promising for fruit yield and Anand, Gaja, Gutkha and NS-443 for seed yield.

Introduction
Bottle gourd [Lagenaria siceraria (Mol.) Standl.] is an
important gourd having wide range of uses and is largely
cultivated in the tropics and subtropics for its edible fruits. Tender
fruits are used as vegetable and also for preparation of sweets
and pickles especially in the hills. It has a cooling effect and
prevents constipation and has diuretic and cardio-tonic
properties. Fruit pulp is used as antidote against certain poisons.
Externally the pulp is applied as poultice and cooling application
to the saved head delirium and also rubbed on the flat of the feet
and hands to diminish the effect of heat. The bitter fruits are
poisonous and are used as a strong purgative. The bitter fruit
ash when mixed with honey is useful application to eyes for
night blindness. The leaves in the form of decoction with sugar
are used for curing jaundice. The hard shells of the mature fruits
are used in making various types of musical instruments, jugs,
domestic utensils for storage of liquid and food materials and
floats for fishing nets.
In spite of being in cultivation since ancient times and the
presence of the wide germplasm, conscious evaluation and
exploitation of germplasm has not been attended to until recently.
Even though the first public sector F
1
hybrid was developed in
this crop, the importance is not given to this crop because of
consumers unknown about nutrients riched value compared to
other cucurbits. At present, urgent need of the farmers is to
develop early maturing and high yielding variety/ hybrid.
Preliminary identification of early maturing genotypes can be
done based on characters like days to opening of female flowers,
node number to first female flowering and days to fruit picking.
Collection and evaluation of germplasm is a pre-requisite for their
utilization and detailed evaluation determines the potential of
an accession in specific crop improvement programme. Therefore,
a trial for characterization and evaluation of presently available
bottle gourd germplasm is carried out in order to identify the
potential cultivar for different horticultural characters.
Material and methods
The study was carried out at the K.R.C. College of
Horticulture, Arabhavi, Gokak Taluk, Belgaum district of
Karnataka state during kharif season of 2010. The material for
the present study consisted 25 diverse genotypes which
comprised of six open pollinated varieties and 19 hybrids. The
experiment was laid out in the randomized block design with
three replications. The net area of the experimental plot was
1215 m
2
. Each treatment or a genotype in each replication was
represented by two rows each accommodating 10 plants at a
row to row spacing of 1.8 m and 0.9 m from plant to plant within
a row. Three plants were randomly selected in each genotype
from each replication and evaluated for the quantitative
characters and the mean values of the data recorded were
analyzed statistically adopting the method suggested by Panse
and Sukhatme (1985).
Results and discussion
The mean values of different growth parameters with respect
to genotypes are presented in table 1. Sarika was found to
possess the maximum number of primary branches per vine
(12.67). In contrast, Kaveri recorded the least number of primary
branches (4.50). In initial stages (45 DAS), INDAM – 320
recorded significantly higher vine length (114.83 cm) but, the
overall vine length at 90 DAS was significantly higher in Anand
Bottle gourd-1 (748.33 cm), and the genotype Elina recorded
the minimum vine length (376.67 cm). Significantly higher
number of leaves per plant was recorded in Gaja (246.00)
followed by Anand Bottle gourd-1 (222.67), Thar Samridhi
(206.83), NS-421 (195.00) and Krushi Sampada (182.33) and
lowest in Elina (65.67) followed by Louki (78.50), Anand (86.83)
and Gutkha (94.67). Gaja recorded the lowest sex ratio (12.62)
and it was significantly highest in Anand Bottle gourd-1 (24.40).
In the present study, the high variation in sex ratio may be due
to environmental conditions.The results obtained are in line

Evaluation of bottle gourd genotypes ......
with those of Pandey and Singh (2007) in sponge gourd, Munshi
and Acharya (2005) and Samadia (2002) in bottle gourd and
Pillai et al. (1998) in bitter gourd.
The genotypes significantly differed for node to first
flowering, node to first female flowering, days to first fruit harvest,
fruit length, fruit breadth, rind thickness, flesh thickness and
total soluble solids (Table 2). Significant early flowering was
recorded in NBBL-12 (43.83) while NBOH-1 was found to be late
of all (58.83). Early male and female flower was produced in
Louki on lower nodes (5.83 and 6.83, respectively) and Champion
produced its first flower on the higher node (12.00). The genotype
NBBL-12 came to flowering early with respect to the female
flower. It took 45.83 days for the first female flower opening and
is also noted for early vegetable harvest with 52.83 days. In
contrast, the genotype Sarika is late many parameters like first
flower opening (60.67), days to first fruit harvest (75.00) and
produced its female flower on a higher node (13.83). The results
are in agreement with that of Pandey and Singh (2007) in sponge
gourd, Kumar et al. (1999) and Sirohi et al. (1988) in bottle gourd.
Among the genotypes the significant difference was
observed for number of fruits per vine, average fruit weight,
fruit yield per vine and hectare, seed yield per fruit and vine,
seed weight and seed yield per hectare (Table 3). Significantly,
higher number of fruits per vine (14.50) was recorded in Gaja
with an average fruit weight of 1104.84 g, which accounted for
higher fruit yield per vine (15.81 kg) and fruit yield per hectare
(41.68 t/ha). Genotypes, NS-421, NBBL-12, Sharada and
INDAM-204 were the next in the order. The maximum fruit weight
of 1443.09 g was recorded in INDAM-320, whereas, the least
fruit yield per vine, per hectare, average fruit weight (2.27 kg,
10.29 t/ha and 698.90 g, respectively) were recorded in Champion.
The results obtained are in agreement with Samadia (2002) and
Sharma and Dhankar (1999) in bottle gourd and Reddy et al.
(1995) in bitter gourd.
The length of fruit ranged from 9.18 cm in Elina a round
fruited variety to 58.92 cm in Anand bottle gourd-1 a long
fruited variety. The fruit of Thar Samridhi was marked for the
maximum fruit diameter (16.33 cm) while fruit of Kaveri recorded
the least diameter (6.25 cm). Similar trend was also observed in
flesh thickness character. The difference in flesh thickness
could be attributed to inherent characteristics of variety. Fruit
flesh thickness increased with increase in size of the fruit i.e.
more thick flesh was observed in bigger sized fruits and less in
small fruits. The highest value for rind thickness (5.49 mm)

was observed in INDAM-320 and least by NBOH-1 (1.57 mm)
which even recorded a significantly higher T.S.S. (6.13

B) and
least was recorded in Champion (2.35

B). The results are similar
to those obtained by Sharma et al. (1997) and Chaudhary and
Singh (1981) in bottle gourd.
Significantly higher seed yield per fruit was reported in
Anand (27.33 g). The same genotype was noted for its higher
seed yield per vine and seed yield per hectare (82.00 g and
5.06 q/ha, respectively). The genotype Champion was
significantly higher for 100 seed weight (23.96 g). The genotype
US-15 was noted for its lower seed yield per fruit, per vine, per
hectare and 100 seed weight (10.73 g, 32.20 g, 1.99 q/ha and
5.98 g, respectively). The results are presented in table 3.
Similar findings were reported by Ram et al. (2006) and Mohan
et al. (2004) in ridge gourd. The increase in seed yield per fruit
may be attributed to the pollinating agents which carried a
good amount of pollen that led to pollination thereby, increasing
seed yield and thus contributed for higher seed weight. The
higher seed yield per vine and per hectare may be attributed to
the number of fruits per plant which increased the yield. On
the other hand, the lower seed yield may be because of
fluctuating temperatures which resulted in poor fruit set and
drying of ovaries and desiccation of tender fruits there by
reducing the yields (Samadia, 2002).

Cabbage (Brassica oleracea L.) crops are frequently attacked by cabbage looper larvae (Trichoplusia ni), which severely reduce cabbage production. This experiment was conducted in the late spring crop season from April 15, 2024, to August 20, 2024, at the Field Science Center for the Northern Biosphere, Hokkaido University, Japan. In this study, the efficacy of an ethanolic extract of bottle gourd (Lagenaria siceraria (Molina) Standl.) leaves was compared with those of the chemical insecticide permethrin 3.2 EC and aqueous dimethyl sulfoxide (DMSO; the control). The experiment was carried out using a randomized complete block design in which each treatment comprised three replications consisting of 24 plants in total. Compared with the control, the bottle gourd leaf extract had high biopesticide activity against cabbage looper, increasing the cabbage yield by 15.98%. The yield was almost equal to that achieved with Permethrin 3.2 EC. Compared with the control, the application of the extract significantly decreased looper larval infestation in field-grown cabbage by 41.18%, 39.71%, 52.08%, and 37.96% at the fifth, sixth, seventh, and eighth weeks, respectively. Five possible biopesticide compounds, namely, apigenin-7-O-glucoside, indole-3-butyric acid, strychnine, phytol and hexadecanoic acid, were identified in the ethanolic extracts of bottle gourd leaves by liquid chromatography-mass spectrometry analysis. Bottle gourd leaf extract has potential as an environmentally friendly and sustainable alternative to toxic chemical pesticides for controlling cabbage looper infestation.

A field experiment was conducted at Vegetable Research Farm, Department of Horticulture, Sam Higginbottom University Institute of Agriculture Sciences conducted to study the effect of Nano Zinc on growth and yield of bottle gourd and their residual effect on succeeding crop. It has laid out by randomized complete block design with 3 replications and 8 hybrids. The factors for the experiment were nano zinc 50ppm and traditional zinc along with the control includes NPK (100:60:40 Kg/ha). The results shown that the highest fruit length (27.67cm), average fruit weight (570.73g), fruit diameter (50.66mm), vine length at last harvest (4.00 m), total no. of nodes at last harvest (44.80), TSS (2.40 0Brix), vit-c(1.30mg/100mg), color of fruit (Light green) and yield q/ha (135.52), marketable yield (136.52) q/ha was reported. Aforesaid hybrids have highest gross return (410870.63 INR/ha), net return (297870.63 INR/ha) and B: C ratio (2.81). zinc levels (50ppm ha1) as soil application found significant influenced the growth, fruit yield, nutrient content, and yield of bottle gourd. It was recorded that 50ppm zinc ha-1 were found best on vine length, fruit girth, number of fruits per plant, seed yield of bottle gourd, zinc content, protein content and growth and yield.
... The genetics of bottle gourd is quite fascinating, because it shows great diversity in traits such as fruit yield, vine length, fruit weight, and others. This variability is caused mostly by its out crossing behavior which had been averaging between 60-80% in previous studies (Harika et al.,2012;Khansa et al.,2024). Such a high level of out crossing increases genetic diversity which allows for unprecedented opportunities for the breeders to evaluate and improve upon economically and agriculturally important traits (Islam et al.,2021). ...

The study was conducted during Kharif season of 2023 in the Experiment Field of Urban Technological Park Habbak, Srinagar, Jammu & Kashmir. The experiment was conducted based on Randomized Complete Block Design (RCBD) with three replications and a plant spacing of 2 × 1 m. A total of 41 bottle gourd genotypes, 2 of which were checks – Pusa Naveen and Pusa Santushti, were studied. Observations were taken on growth, yield attributes, seed traits and quality parameters. Analysis of variance showed considerable differences exist among the genotypes for all the traits. The phenotypic coefficient of variation (PCV) was found marginally greater than the genotypic coefficient of variation (GCV) for all the traits, which indicates insignificant environmental influence. For the seed cavity width the highest PCV and GCV values were recorded 56.43 and 56.33 respectively. The high estimates of heritability along with high genetic gain were observed in fruit diameter (0.990 and 79.83) which suggests that selection would be effective due to the predominance of additive genetic effects. Broad-sense heritability estimates across all the traits appeared high ranging from 77% to 99%. Correlation analysis revealed strong positive relationship between fruit yield per hectare and fruit yield per plant, average fruit weight, vine length, number of primary branches, and number of fruits per plant. The assessment by the path coefficient analysis results showed that the strongest direct effects were: average fruit weight, number of primary branches, number of fruits per plant, and vine length on the yield per hectare.

An experiment was conducted at the Vegetable Research Farm, Maharajpur, Department of Horticulture, JNKVV, Jabalpur in kharif season of 2022 and 2023. The current study evaluated the performance of 23 bottle gourd genotypes, including 6 parental lines, their 15 diallel crosses, and 2 checks, focusing on their quality traits. Over two years of pooled data, genotype, JBG-4×JBG-5 was found to possess maximum TSS (3.93 °Brix), followed by JBG-2×JBG-4 (3.77 °Brix). JBG-4×JBG-5 was found to have maximum ascorbic acid content (14.48 mg 100-1 g) followed by JBG-4 (14.01 mg 100-1 g). Rind thickness was found maximum in JBG-2×JBG-4 (3.36 mm) followed by JBG-2×JBG-3 (3.28 mam). This study found a substantial association between the total soluble solids (TSS) and ascorbic acid content with the yield of bottle gourd genotypes. Among the genotypes, JBG-4×JBG-5 demonstrated the highest yield per plant, along with the highest total soluble solids (TSS) and ascorbic acid content. Regarding heterosis, JBG-4×JBG-5 has found the highest heterosis for total soluble solids and ascorbic acid content. JBG-4 and JBG-2 are the best general combiners for TSS, ascorbic acid content, and rind thickness. JBG-4×JBG-5 has found the best specific combiner for TSS and ascorbic acid content.
... The variation might have been due to genetic or environmental reasons, which is mainly responsible for the growth of the crop. Similar results were obtained by Harika et al.

The objective of our study was the collection and characterization of germplasm of different species of cucurbitaceae followed by its evaluation for drought tolerance. Characterization of two species of Luffa (9 genotypes), two species of Cucumis (12 genotypes), one species of Lagenaria (2 genotypes), one species of Cucurbita (2 genotypes), one species of Citrullus (one genotype) and one species of Momordica (one genotype) were done based on 15 characters including internodal length, days to first female flower opening, node number of first female flower etc. Among Luffa species, days to first female flower opening ranged from 28.66 to 42.00 days. In Cucumis callosus it ranged from 18.28 to 22.00 days.From this, twenty genotypes were evaluated for drought tolerance in a pot culture experiment.Higher proline content under water deficit was found in Momordica genotype IC-373784(212.69 ug g⁻¹ of fresh wt.). Diphenyl picrylhydrazyl (DPPH) free radical scavenging activity was generally higher under water deficit and it was more pronounced in Cucumis melo var. momordica genotype AHS 82 (76.05%).The reduction in the photosynthesis rate was less in Cucumis melo var. momordica (from 11.73 to 10.85 µmol CO2 m⁻² s⁻¹). From this study, four genotypes of Cucumis melo var. momordica (IC-274017, IC-274007, IC-331085 and AHS 82) three genotypes of Cucumis melo var. callosus (IC-641436, AHK 119 and IC-351039) and one of Momordica charantia var. muricata (IC-373784) were identified as drought tolerant.

Genetic variability and heritability of different characters were studied in ridge gourd (Luffa acutangula L.) with 80 genotypes. High degree of variation was observed in respect of all the characters studied. The estimates of genotypic coefficient of variation were low as compared to phenotypic coefficient of variation for all the characters under study. The highest GCV and PCV was observed for sex ratio on branches. High heritability coupled with high genetic advance (%mean) was observed for node number for appearance of first male and female flower, length of main axis, number of primary branches, male and female flowers/plant, sex ratio on whole plant, main axis and branches; fruits/ plant, fruit set (%), fruit length, fruit weight, seeds/fruit, 100-seed weight and yield/plant, indicating greater scope of improvement through selection. The critical assessment of nature and magnitude of variability is one of the important pre-requisite in formulating effective breeding methods The efficiency of selection depends mainly on the extent of genetic variability present in a population. The genetic improvement of any crop depends on magnitude of genetic variability and the extent of heritability of economically important characters. Of course, alongwithgenetic component the part played by the e~vironment in the expression of such characters also needs to be taken into account. Since information on these aspects in ridge gourd (Lufla acutanguJa L) is mearge. Reddy and Rao (1984) Kadam and Kale (1987); Sahni et al (1987), an effort was made to assess the existing variability, heritability and genetic advance in the crop.
