Abstract:
The present investigation consist of 18 local land races rice genotypes provided from local farmers of Patna district. The genotypes were evaluated during Kharif 2012. The exeperinments was conducted in randomized block design having three replications. The data were recorded on 13 characters to study the analysis of variance, heritability, genetic. Advance, coefficient of variation based on the mean performance genotype ‘SANGAM’ was identified as best genotypes for seed yield per hill; High phenotypic and genotypic coefficient of variation was observed for number of fillers per plant, flag leaf width number of panicles per hill, flag leaf length and seed yield per plant, suggesting the possibility of yield improvement through selection for these characters. High heritability coupled with genetic advance was observed for days to 50% flowering, number of panicles per hill, flag leaf width, harvest index flag leaf width, harvest index flag leaf length indicating that these characters predominantly governed by additive gene action and these characters may be helpful for yield improvement in rice. Land races harbor a great genetic potential for race improvement. Whereas genetic varability (GCV and PCV) helps to choose the potential genotypes. Heritability along with genetic advance would be move useful tool in predicting the resultant effect from selection of the best genotypes for yield and some of its components in rice.
