Under the changing climatic conditions due to aberrations of weather parameters, there is a change in the microclimate vis-a-vis change in the pest and disease scenario of crops that are widely cultivated. Sugarcane, being a long-duration crop grown on a larger scale across many states in India, often encounters the vagaries of weather conditions o...

Sugarcane (Saccharum spp hybrid) is grown across the continents, principally for white sugar and bioethanol. It is a C4 plant, generates highest amount of biomass among the cultivated crops, and meets nearly 80% of the global white sugar requirement. The modern cultivated sugarcane is a derivative of Saccharum officinarum (noble canes) and the wild...

The genetic improvement efforts in sugarcane are largely centered around increasing its sucrose accumulation potential. Sugarcane genotypes show variable regulation of genes involved in synthesis, accumulation, transport, storage and subsequent retention of sucrose. MicroRNAs (miRNAs), which are a class of small non-coding RNAs play a very importan...

The utilization of superior parental lines and identification of superior families enhance the genetic gain in sugarcane. To identify the superior parental lines and superior progenies, 1889 progenies derived from twenty crosses involving genetically diverse historical parents were evaluated for juice quality and yield attributing traits.The hist...

Thirty-one sugarcane genotypes were planted in the experiment and post-emergence application of Halosulfuron Methyl 75% WG and Metribuzin 70% WP was carried out at the rate of 67.5 g and 1000 g a.i. per hectare on 42 days after planting (DAP). Lower leaves of some of the genotypes were found to show injuries on 5 days after spraying (DAS). Phytotox...

The breeding gene pool maintained in ICAR-SBI, Coimbatore serves as the prime source for generating genetic variability for sugarcane varietal development in India. About 417 parents from five different zones of sugarcane cultivation in India, exotic hybrids and interspecific hybrids, were initially tested for their resistance against the tropical...

Sugarcane being a heavy biomass producer needs enormous quantity of nutrients. Soil has to be replenished with the quantities of nutrients utilized by the crop to maintain the productivity as well as soil quality. Partitioning of nutrients (N, P and K) in the aerial parts of sugarcane genotypes entered in the advanced varietal trial (AVT) during 20...

Improvement of parental clones of Saccharum officinarum L. through repeated cycles of intra-specific hybridization and selection was undertaken at ICAR-Sugarcane Breeding Institute (SBI), Coimbatore during 1987 to 1996. Thirty one clones selected from six polycrosses involving 13 parental clones of S. officinarum constituted cycle 1 (C1) population...

Field experiments were conducted during 2016-17 and 2017-18 crop seasons with twenty test clones viz., Co 0238, Co 0240, Co 06031, Co 09004, Co 11015, Co 13001, Co 13003, Co 13006, Co 13014, Co 13018, Co 13020, Co 13021, Co 14008, Co 14016, Co 14026, Co 15005, Co 15007, Co 15021, Co 16001 and Co 16002 along with three standards viz., Co 86032, Co 0...

Improvement of Saccharum robustum, a wild species of Saccharum through repeated cycles of intra-specific hybridization and selection was undertaken at ICAR-Sugarcane Breeding Institute, Coimbatore during 1987-1996. Thirty four clones selected from six polycrosses involving 13 clones of S. robustum constituted Cycle 1 (C-1) hybrids. Inter-mating amo...

Co 10026 (UPAHAR): New Early Maturing Variety Released for Cultivation in Peninsular Zone

Genomic constitution of commercially cultivated sugarcane varieties over the world is derived from few basic species clones of Saccharum complex. In order to impart new cytoplasmic and nuclear genome in sugarcane hybrids, untapped wild species of Saccharum spontaneum (S), Erianthus arundinaceus (E) and E. bengalense (Eb) were utilized to produce di...

The cytoplasmic and nuclear genomic diversity in commercially cultivated sugarcane varieties over the world is derived from few basic species clones of Saccharum complex. To impart new cytoplasmic and nuclear genome in sugarcane hybrids, untapped wild species of S. spontaneum (S), Erianthus arundinaceus (E) and E. bengalense (Eb) were utilized to p...

Six soybean accessions viz., TNAU S 7, TNAU S 55, DS 9501, TS 82, Himso 1563 and CO 2 and their 15 F1 and five F2 populations were taken with the objective of studying their response to gamma radiation. Among the parents, TS 82 and Himso 1563 were highly sensitive while CO 2 was less sensitive to the mutagen. Analysis of variance showed significant...

Intensive flowering and good seed set are the two important parameters for generating more genetic variability which is the foundation for national sugarcane varietal development programme. Five hundred and forty-eight parental clones including those representing five different agro climatic regions of sugarcane cultivation in the country being mai...

The understanding on the available genetic variability in the breeding pool aids the breeder to choose better parental combinations for the desired genetic improvement in crop plants. The variability present in the National Hybridisation Garden (NHG) of sugarcane in India at Sugarcane Breeding Institute, Coimbatore with an assemblage of 606 clones...

The ancestry of 59 sugarcane breeding stocks used to develop.nearly 80% of (Co' sugarcane cultivare during 1970-2009, was studied. Thirteen Saccharum officinarum, two S. barberi, two S. spontaneum and one Erianthus arundinaceus species clones were involved in their evolution. Species clones, Black Cheribon, Bendjermasin Hitam, Loeithere, Fidji, Lah...

The pedigree of the commercial sugarcane varieties ('Co'canes) evolved from Sugarcane Breeding Institute, Goimbatore, India during 1970-2009 was studied. A total of 1088 'Go' canes with known pedigree were evolved, among them 934 were from bi-parental crosses. The decade wise usage of breeding stocks revealed that clones Go 86011 (during 2000-2009)...

Searching rice cultivars or variety with good processing and high in important essential nutrients are prime important in the present context of rice research. The north eastern hill region of India which is a mega biodiversity hot spot of the world has numerous cultivars of rice with tremendous potential of high quality rice. Eighteen indigenous c...

Manipur, a northeastern state of India lying in the Indo-Burmese biodiversity hot-spot is endowed with rich biodiversity of rice cultivars including those with medicinal values. The systematic evaluation of the indigenous cultivars for their grain and food qualities has not been carried out yet. Hence 13 indigenous medicinally used cultivars were s...

This paper aims to discover the genetic parameters underlying the physiological efficiency and panicle characters of hill rice plants. In order to improve these characters, it is crucial to learn the nature and magnitude of gene action involved in inheritance of panicle and physiological traits. With this purpose, we combined a line×tester analysis...

Five hundred and twelve soybean germplasm accessions were evaluated for 11 agronomical traits and characterized with respect to 18 morphological characters. A wellrepresented sample collection was derived based on the agronomical data. Through principal component analysis it was inferred that number of clusters per plant, total number of pods per p...

About 10000 indigenous rice cultivars are available in northeastern India and nearly 9000 rice germplasm accessions have been collected since 1955. During the present exploration 397 accessions were collected. Evaluation and characterization of these accessions revealed greater variability in leaf characters, maturity traits and plant height The de...

The northeastern hills of India are endowed with rich source of rice germplasm, which may be safely estimated about 9,000 accessions, excluding the redundancies. Even though much of the germplasm have been collected, studies on nutritional aspects of these local cultivars are still lacking. Fifteen important indigenous rice genotypes collected from...
