ABSTRACT
In a population of 120 plants (HKR47 x BR4-10) a large variation was observed for all physio-morphological traits and Fe & Zn contents [Plant height(72.62-137.46cm); Effective No. of tillers/plant (8-14); Panicle length (13.35-30.59 cm); Grain yield/plant (9.84-24.51 g); 1000 grain wt. (17.14-27.93 g); L/B ratio of grain (2.14-4.01); Days to 50% flowering(85-109);Grains/panicle (68-161);days to maturity(129-134);Grain colour (1-4) Fe content (9.0-188.40 mg/kg); Zn content (19.80-96.10mg/kg)].
In F3 & F4 population of HKR47 x BR4-10 four plants identified will be used for further progenies [Plant No. 64(Fe 179.40 and Zn 95.50 mg/kg); 68 (Fe 180.80 and 68.30 mg/kg); 70 (Fe 183.10 mg/kg and 96.10 mg/kg); 71 (Fe 97.50 and 54.50mg/kg); HKR47 (Fe 54.3 and Zn 25.4mg/kg); BR4-10 (Fe 176.2 and Zn 23.2 mg/kg)]. Phenotypic correlation coefficient analysis of HKR 47 x BR4-10 population showed that Fe content is positively and significantly correlated with Zn content (0.0299, p=0.01). in this population grain yield/plant is positively correlated with plant height (0.186, p=0.05), effective numbers tillers/plant (0.217,p=0.01) and panicle length (0.342, p=0.01). plant height showed significant and positive correlation with effective numbers tillers/plant (0.217, p=0.01) and negative correlation with Zn content (-0.268, p=0.01). 1000 grain weight showed positive and significant correlation with Fe content (0.217, p=0.01) and negative correlation with Zn content (-0.251, p=0.01). Effective number of tillers/plant showed significant and positive correlation with panicle length (0.266, p=0.01). L:B ratio of grain showed negative correlation with Fe content (-0.153, p=0.05).
Key words: Rice Genotypes, yield, Fe and Zn.
