Genetic characterization and population structure of Indian rice cultivars and wild genotypes using core set markers

Abstract: Genetic diversity among 23 rice genotypes including wild species and cultivars of indica, japonica, aus and aromatic type was investigated using 165 genomewide core set microsatellite (SSR) markers. This genotypic characterization was undertaken to know the genetic similarity among the parental lines to be used in developing a set of chromosome segment substitution lines. In all, 253 alleles were identified using 77 polymorphic SSRs, and polymorphism information content ranged from 0.31 to 0.97 with a mean of … Show more

“…Rice ( Oryza sativa L.) is increasingly becoming a major food crop in sub-Saharan Africa (SSA). Globally, rice is one of the most widely cultivated cereal crops distributed across diverse geographical, ecological and climatic conditions [ 1 , 2 ]. Given the varied adaptations of rice genotypes, several accessions are available with wide phenotypic and genotypic diversity [ 3 ].…”

“…This is important as a potential source of reservoir genes that could be exploited in crop improvement programs [ 5 , 6 ]. However, only a slight amount of the available rice genetic resources have been utilized in most rice breeding programs [ 1 ], hence a great genetic similarity exists in most commercial rice cultivars given the narrow genetic base [ 3 ].…”

“…In this study, genetic diversity among the tested germplasm was also evaluated by a model-based structure using the SSR genotypic data. The genetic architecture of diverse germplasm can be estimated by determining the STRUCTURE of the population using molecular markers such as, but not limited to, SSRs or SNPs 16 , 21 , 30 , 40 , 59 , 60 . In STRUCTURE, LnP(D) denotes the highest optimal number of subsets (K) 61 63 for an optimal number of divisions 64 .…”

“…Rice (Oryza sativa L.) is one of the most extensively cultivated cereal crops in the world, spreading across a wide range of geographies, ecological and climatic regions (Surapaneni et al, 2016). Rice is the life and the prince among cereals as this unique grain helps to sustain two thirds of the world's population.…”
