چکیده
The present investigation was carried out to estimate indica-tropical japonica genome proportion in two newly developed wide compatible restorer lines (RP6367 and RP6368) derived through crosses study the molecular diversity among 12 rice genotypes namely, five promising indica restorers (RPHR1005, RPHR1096, IBL57, DR714-1-2 Akshayadhan), maintainers (IR58025B APMS6B), identified (RP6367and RP6368), typical tropical (IRGC66651 IRGC66577) one genotype (Nagina22) using 50 SSR markers 45 InDELs. Out of 95 markers, 54 were found be polymorphic. genotypic data polymorphic used genotypes. percentage RP6367 RP6368 50% 55.55% respectively. Our results suggest that hybrid parental is key select best parents for efficient utilization heterosis between subspecies. 19 recorded PIC value above 0.5 can considered as highly informative useful genetic diversity. In this study, SSRs primers showed higher values compared InDels. It concluded use detected gives a better understanding relationship closely related Keywords: Hybrid Rice, Genome proportion, Molecular diversity, SSRs,

Overcoming inter-subspecific hybrid sterility in rice by developing indica-compatible japonica lines
Rice (Oryza sativa L.) is an important staple crop. The exploitation of the great heterosis that exists in the inter-subspecific crosses between the indica and japonica rice has long been considered as a promising way to increase the yield potential. However, the male and female sterility frequently occurred in the inter-subspecific hybrids hampered the utilization of the heterosis. Here we rep...
متن کاملGenome-Wide Association Analysis Reveals Different Genetic Control in Panicle Architecture Between Indica and Japonica Rice
Panicle architecture determines the number of spikelets per panicle (SPP) and is highly associated with grain yield in rice (Oryza sativa L.). Understanding the genetic basis of panicle architecture is important for improving the yield of rice grain. In this study, we dissected panicle architecture traits into eight components, which were phenotyped from a germplasm collection of 529 cultivars....
متن کاملIdentification of Genome-Wide Variations among Three Elite Restorer Lines for Hybrid-Rice
Rice restorer lines play an important role in three-line hybrid rice production. Previous research based on molecular tagging has suggested that the restorer lines used widely today have narrow genetic backgrounds. However, patterns of genetic variation at a genome-wide scale in these restorer lines remain largely unknown. The present study performed re-sequencing and genome-wide variation anal...

Doubled haploid (DH) populations, particularly those from subspecies crosses possessing the wide compatible gene S5n , are important germplasm resources for rice genetic studies and breeding, but their feature and potential have not been fully assessed and explored. In the present study, we produced a DH population from the hybrid of japonica 668B and wide compatible indica T23. Genotyping of t...
