Genetic variability studies in rice (Oryza sativa) genotypes of Assam for ratooning ability and perennation
نویسندگان
چکیده
An experiment was conducted at the research farm of Assam Agricultural University, Jorhat, during 2020–22 to assess genetic variability among 50 rice (Oryza sativa L.) genotypes with respect ratooning ability and perennation. Out genotypes, only 30 showed different degree ratoon production yield. All showing better mainly belonged photo-insensitive group few were slightly photosensitive. True perenniation as expressed by formation rhizome (O. longistaminata) not observed in any genotypes. However, stolen O. rufipogon 1 genotype Terabali. ANOVA result suggested presence statistically significant all both main crop. Genotypes, viz. Binadhan-11, Sayjihari IR-64 found be best performing for desirable crop traits. High heritability coupled high advance estimated traits except days maturity indicating involvement additive gene action expression

Present investigation was conducted to estimate the per se performance, combining ability and heterosis for grain quality traits in rice using line × tester mating design. Analysis of variance with respect to crosses revealed significant differences for all the traits studied. GCA and SCA results revealed the predominance of SCA variance in relation to GCA variance for all the traits. For aroma...

Genetic diversity in 40 traditional boro rice genotypes was studied under irrigated condition through Mahalanobis D 2 statistic for grain yield and yield contributing characters. The genotypes were grouped into five clusters. The inter-cluster distances were higher than intra-cluster distances indicating wider genetic diversity among the clusters. The intra-cluster distances were lower in all t...
