Salinity has a significant impact on rice production in coastal, arid and semi-arid areas in many countries, including countries growing temperate rice, such as Kazakhstan. Salinity tolerant temperate japonica rice accessions were identified in this study, these accessions are important resources for breeding programs. SNPs located in the promising QTLs and candidate genes could be used for future gene validation and marker assisted selection.

The aim of the present study was to examine the diversity for heat tolerance in a set of 105 accessions using some key morphophysiological attributes. The data was standardized by calculating percent change over control, and used for phonetic analysis and construction of dendograms based on distance matrix (all primary data is given as supplementary material listed in statistical analysis section of Materials and Methods).

In this study, the genotypes of melon in Kyrgyzstan were collected by visiting several regions and contacting farmers. The genetic diversity of 35 Kyrgyz and 13 Turkish melon accessions was characterized based on the corresponding phenotypes. The morphological characterizations were largely based on the IPGR and, to some extent, UPOV standards.

Reniform nematode (Rotylenchulus reniformis) has emerged as one of the most destructive root pathogens of upland cotton (Gossypium hirsutum) in the United States. Management of R. reniformis has been hindered by the lack of resistant G. hirsutum cultivars; however, resistance has been frequently identified in germplasm accessions from the G. arboreum collection.

Productivity of cowpea [Vigna unguiculata (L.) Walp] in sub-Sahara Africa is curtailed by a lack of farmer-preferred and improved cultivars and modern production technologies. The objectives of the study were to determine the extent of genetic diversity present among a collection of cowpea accessions from Zambia and Malawi using phenotypic traits and single nucleotide polymorphism (SNP) markers and, to select distinct and complementary parental lines for cultivar development.

Eclectic variation between Indiana and the rest of the accessions for both agromorpho-economic traits and molecular markers affirms its potential usefulness as a source of diverse genes for future breeding programmes. Sequencing of regions from all accessions, suggests that they are identical with a common ancestry. Outcomes of this study is timely for an ongoing okra hybridisation programme in Ghana.

Due to the recent domestication of peanut from a single tetraploidization event, relatively little genetic diversity underlies the extensive morphological and agronomic diversity in peanut cultivars today. To broaden the genetic variation in future breeding programs, it is necessary to characterize germplasm accessions for new sources of variation and to leverage the power of genome-wide association studies (GWAS) to discover markers associated with traits of interest.

Breeding programs benefit from information about marker-trait associations for many traits, whether the goal is to place those traits under active selection or to maintain them through background selection. Association studies are also important for identifying accessions bearing potentially useful alleles by characterizing marker-trait associations and allelic states across germplasm collections.

The importance of Indian germplasm as origin and primary center of diversity of cultivated melon is widely accepted. Genetic diversity of several collections from Indian has been studied previously, although an integrated analysis of these collections in a global diversity perspective has not been possible.

The United States Department of Agriculture (USDA) National Plant Germplasm System (NPGS) sorghum core collection contains 3011 accessions randomly selected from 77 countries. Genomic and phenotypic characterization of this core collection is necessary to encourage and facilitate its utilization in breeding programs and to improve conservation efforts.

Unravelling the genetic architecture of agronomic traits in walnut such as budbreak date and bearing habit, is crucial for climate change adaptation and yield improvement. A Genome-Wide Association Study (GWAS) using multi-locus models was conducted in a panel of 170 walnut accessions genotyped using the Axiom™ J. regia 700 K SNP array, with phenological data from 2018, 2019 and legacy data.

Apple (Malus ssp.), one of the most important temperate fruit crops, has a long cultivation history and is economically important. To identify the genetic relationships among the apple germplasm accessions, wholegenome structural variants identified between M. domestica cultivars ‘Jonathan’ and ‘Golden Delicious’ were used.

In field pea germplasm a wide range of genetic variability is present for various morphological traits; In this regard, present genotypes were dimly characterized for these morphological descriptors to establish DUS. DUS test is important so that new varieties can achieve legal access to their market or their protection under PPV&FR Act, 2001. The present paper focuses on DUS characterization for 126 genotypes of field pea with diverse origin including four checks viz., HFP 8909, HFP 715, HFP 529 and HFP 9426 grown in Augmented Design. The study was carried out during Rabi season 2018-19.

The present study was carried out with one hundred genotypes of foxtail millet procured from ICRISAT mini core collection (Upadhyaya et al., 2011) for Lysine content. The range of values for these parameters ranged from 0.49-2.45 respectively, ISe 1610 (0.49g/100g of protein) recorded least amount of Lysine whereas ISe 1187 recorded highest amount of Lysine (2.45g/100g of protein). The study also reveals great variability existing among the collection of Italian millet accessions for Lysine that can be exploited to improve the cultivars to meet the nutritional requirements of humans.
