Dill, Anethum graveolens L., is grown in various regions of the world. It has been used as vegetable and medicinal plant since ancient times. Seed quality is important in dill cultivation and there is limited information on the effects of cutting treatment in this species. This research was carried out to find out the effect of cutting treatment on...

Dill seed production was investigated over two seasons, comprising a spring growing cycle (SGC) and an autumn growing cycle (AGC). The effects of growing cycle on phenological traits, yield and quality of dill seeds formed on different umbels of the mother plant were investigated. Significant differences were noted in the flowering period, seed yie...

High-Throughput Illumina Sequencing (HTS) can be used to study metagenomes, for example, those of importance for plant health. However, protocols must be optimized according to the plant system in question, the focal microorganisms in the samples, the marker genes selected, and the number of environmental samples. We optimized the protocol for meta...

Abstract Turkey, one of the secondary centers of the melon, has lots of local melon varieties. Many of them have not been produced commercially although there is considerable variation in fruit size and shape, taste, brix and storability and disease resistance which are important for breeding programmes. In this study, local melon varieties and com...

This study was carried out to determine whether a single radicle emergence count (RE) during germination can be used for vigour assessment to estimate field emergence of marigold (Tagetes spp.) seed lots. Six marigold seed lots (Tagetes erecta and T. patula) with normal germination above 75% were germinated using the standard ISTA germination test...

Tomato (Solanum lycopersicum L.) is the most produced and exported vegetable in Turkey. There are many pathogens to limit tomato production by reducing yield and fruit quality. Among them, Tomato Yellow Leaf Curl Virus (TYLCV) causes important economic losses. The most efficient and environmentally friendly method against TYLCV is the use of resist...

Development of an efficient plant regeneration protocol is essential for vegetable crop advancement by biotechnological methods. In this study, regeneration protocols of four pepper lines of different pepper types were optimized. Different protocols for organogenesis were investigated in regeneration experiments. Optimum plant regeneration was obta...

Daffodil (Narcissus L. spp.) is one of the oldest ornamental flowers that have been cultivated from ancient times to nowadays. The species Narcissus tazetta L. and N. serotinus L. have spread out in different regions of Turkey and some other species have been naturalized. The purpose of this study was to characterize some daffodil populations that...

Clavibacter michiganensis subsp. michiganen-sis (Smith) Davis et al (Cmm) is an important bacterial agent for tomatoes causing destructive disease. The best way to control of this disease is to use resistant cultivars. Unfortunately there has not been developed a resistant variety against the Cmm because the heritability of resistance is quite comp...

The Russian Wheat Aphid (RWA), Diuraphis noxia (Kurdjumov), is an important pest of small-grain cereals, particularly wheat in Turkey and worldwide. The most efficient struggle with the RWA is to identify of resistance sources and introduce resistance genes into susceptible wheat genotypes by means of different plant breeding methods and marker-ass...

Bacterial canker is one of the most important diseases causing economic yield loss in tomato production areas in the world. The best way to control for this disease is to use resistant varieties. However, there are few studies on variety breeding studies of this disease compared with other disease resistant breeding studies. In this study we aimed...

The Russian wheat aphid (RWA), Diuraphis noxia (Kurdjumov), is an important pest of small-grain cereals, particularly wheat, worldwide. The most efficient strategy against the RWA is to identify sources of resistance and to introduce them into susceptible wheat genotypes. This study was conducted to determine the mode of inheritance of the RWA resi...

Key message We developed highly reliable co-dominant SCAR markers linked to the Frl gene. FORL testing is difficult. The marker is expected to be quickly adapted for MAS by tomato breeders. Abstract Fusarium oxysporum f. sp. radicis-lycopersici causes Fusarium crown and root rot (FCR), an economically important soil-borne disease of tomato. The res...

This study was conducted to determine storage potential of white-seeded beans using the electrical conductivity and accelerated ageing tests recommended by ISTA for legumes. For this purpose, eight seed lots of flve white-seeded cultivars from research institutes and seed companies were stored at 5°and 25°C up to 10 months. Seed quality was determi...

Climate change is expected to cause drastic changes in the incidence of disease and pests throughout the world, also leading to the occurrence of highly variable insect pests. One approach to minimize the losses in crop yields due to highly variable insects is the introgression of multiple resistance genes into adapted crop cultivars. The objective...

Rocket (Eruca spp. and Diplotaxis spp.) is widely cultivated as a green vegetable in Mediterranean countries, Europe, United States and Brazil, but few rocket cultivars are available and limited variety selection has taken place. Plant genetic resources and germplasm are fundamental sources for plant breeding, and the assessment of the genetic dive...

Pre-breeding research has a significant role in linking between genetic resources and breeding as it shortens the time frame between genetic enhancement and the development of new, improved crop varieties. The Russian wheat aphid (RWA), Diuraphis noxia, is one of the most damaging insect pests of wheat and barley throughout the World. Although it i...

Eruca sativa L. (rocket or arugula) and Diplotaxis tenuifolia L. (perennial wall-rocket), are important leafyvegetables and are significant sources of minerals for human nutrition and commonly found in the Mediterranean basin,southern Europe, and Central Asia. The objectives of this study were to determine genotypic variability among and within E.s...

An alternative to the cold test to evaluate maize seed vigor was investigated. The standard germination test, cool germination tests at 12, 15 and 18°C, the cold test were performed for seven maize seed lots and field emergence at one site determined. The standard germination of all lots was >90% and was not correlated with field emergence, but the...

The controlled deterioration (CD) test is a vigour test for small seeded vegetables. Thirteen pepper (Capsicum annuum L.) seed lots were deteriorated at 24% seed moisture content for 24, 48, or 72 hours at three different temperatures (41, 43 and 45°C), to determine the optimum test conditions, in terms of temperature and ageing period. Germination...

Seed vigor testing is now a common practice for quality control of seed lots. For pepper seed lots, there is no vigor test that has been widely accepted or suggested by ISTA. This research has been carried out in order to develop a possible procedure of controlled deterioration test that can be used as a vigor test method for pepper seeds. As the f...

'Sakiz' and 'Bayrampasa' are two local artichoke varieties with extended growing areas and an important contribution to the Turkish artichoke production. It is also known that, depending on the cultivation time, c.v. 'Sakiz' is irreversibly divergening to the "Yerli type of artichoke". The extent of genetic variation among them is still unknown. It...

Twenty-eight seed lots of two onion cultivars (Diana F1 and Aki) were created by naturally aging seeds during storage at 10% MC and 5° and 25°C for up to 22 months to investigate the ability of the vigour tests to identify differences in the extent of seed aging and possibly vigour. All seed samples were subjected to the following tests: standard g...

Analysis of Random Amplified Polymorphic DNA (RAPD) was evaluated as a tool for testing hybrid purity in tomato varieties. Four F1 tomato hybrids (L. esculentum Mill.) and their parents were analyzed with eight 10-mer primers. Out of the primers tested, five primers generated useful RAPD markers to determine the hybrid seed purity of three varietie...

The potential of randomly amplified polymorphic DNA (RAPD) markers in varietal identification and genetic purity test of hybrid varieties was evaluated. Five Jalepeno hybrid varieties and their corresponding parents were screened for polymorphic RAPD markers with 12 arbitrary 10-mer primers. Among a total of 177 bands observed, 14 bands contributed...
