Abstract:
The agro-morphological characterization was done among ninety genotypes of restorer line of rice for 15 quantative traits under Rice improvement Project, seed breeding farm, department of Pant Breeding and genetics, JNKVV, Jablapur, M.P. The random plants were selected for characterization and the phenotypic assessment revealed polymorphism in almost all phenological, yield and quality attributing traits. While commonness were found in traits via., long leaf length, medium leaf width, medium (91-110days) days to 50% flowering, thick (>0.55) stem, few (<11) panicle number, medium (120-140 days) time of maturity, medium (21-25 g) weight of 1000 fully developed grain and fully restore spikelet fertility percentage. The evaluation extracted elite morphological markers in genotype SUGANDHA -3 for grain quality; CNAP 318 and JR-1001 for phenological traits and PRR 78 for yield attributing traits via, lodging resistance, semi-dwarfness and high 1000 grain weight. The wide variation depict that the hybridization could obtain transgressive segregates, while superior restorer could help in gaining high yielding hybrids with full exploitation of heterotic potential.
