Description

Development of hybrid genotypes/ high yielded varieties more demand to fill the gap between food production and human population.Heterosis and Combining Ability Studies in Brassica napus leads to develop the hybrid genotypes/ Varieties which will be produce more seed yield, plant biomass(fodder or Saag), oil contents, protein contents and canola type traits for good health.In an experiment Sixteen genotypes were crossed among eleven lines and five testers in Line × Tester mating design (11x5),55 F1 were made and Data of hybrids and their parents were recorded for various seed yield and yield contributing traits. The results revealed that highly significant values were found in line x tester interaction for all the traits except the character days taken to 50% maturity. The estimates of SCA variance was noticed higher than GCA variance in all the recorded traits.The significant potence ratio were explained that the transformation of desirable gene in all the recorded traits of genotypes in dominance type of gene action for the development of hybrids or varieties in Brassica napus.
