Genetic diversity, population structure and allele mining of genes governing grain size related traits in rice (Oryza sativa L.)
The present study was undertaken for allele mining of genes governing grain dimensions viz., grain length, grain width, grain thickness, grain size and grain weight. The molecular markers linked to the reported genes for these traits were used to screen 124 diverse rice genotypes. Thirty-tw...

Summary: | The present study was undertaken for allele mining of genes governing grain
dimensions viz., grain length, grain width, grain thickness, grain size and
grain weight. The molecular markers linked to the reported genes for these
traits were used to screen 124 diverse rice genotypes. Thirty-two molecular
markers used in this study produced a total of 86 alleles among 124 rice
genotypes. The number of alleles ranged from 2 to 4 with an average of 2.58
alleles per locus. A dendrogram consisting of 124 rice genotypes revealed
that all the genotypes can be divided into two groups. An analysis of the
model-based population structure using simple sequence repeats (SSRs)
covering all 12 chromosomes provided evidence of a significant population
structure in the rice genotypes. The novel alleles identified in the study
could be of great value for development of consumer-targeted rice varieties. |
