Studies on variability, heritability, genetic advance and path analysis in some indigenous Aman rice (Oryza sativa L.)
308 The variability in the breeding material is extremely important in the selection of superior type plant, where selection is based not only on yield but also on its component traits. Such information on segregating population, where selection is actually practiced, will be more meaningful and of immediate practical utility. Moreover, most of the yield component traits are quantitative in nat...
متن کاملGENETIC VARIABILITY, HERITABILITY AND CORRELATION COEFFICIENTS OF GRAIN QUALITY CHARACTERS IN RICE (Oryza sativa L.)
Ninety-two rice (Oryza sativa L.) genotypes were evaluated during kharif 2013 to estimate the genetic variability, heritability and correlation coefficients for 14 physicochemical and cooking quality traits. The experiment was conducted in a complete randomized block design with 3 replications. Highly significant (P < 0.01) differences were observed for all 14 quality characters studied. Among ...
متن کاملEvaluation of genetic parameters and heritability of traits in rice (Oryza sativa L.) using diallel method
To study the genetic control of grain yield and its components in rice using Hayman graphical method, 56 progenies obtained from diallel mating with eight parents (64 genotypes in total) were evaluated using randomized complete block design with three replications at research field of the Rice Research Institute of Iran in 2013. Agronomic traits, grain yield and its components were measured and...
متن کاملGenetic Variability, heritability and genetic advance studies in Carrot (Daucus carota var. sativa L.)
A study was carried out in mungbean Vigna radiata (L.) Wilczek) with eight ‘lines’ and four ‘testers’ crossed in a Line x Tester Genetic variability, heritability and genetic advance were estimated for marketable and its component yield traits in 48 lines of carrot (Daucus carota var. sativa L.). The study showed high ranges for total yield (3.15 -7.56 kg/plot), marketable yield (2.60 – 6.85 kg...
متن کاملHeritability and genetic advance in rapeseed (Brassica napus L.)
The present study was carried out to estimate genetic variability parameters for some traits such as pods per plant, cell membrane stability, one thousand kernel weight, flowering period, grain filling period, chlorophyll content, relative water content, leaf excised water content, seed per pod and pod length, in 16 winter rapeseed genotypes. Statistical analysis showed significant differences ...
