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 x Tester mating design (11x5),55 F1 were made and Data of hybrids and their parents were recorded for various seed yield and yield...

Development of hybrid genotypes more need to increase the edible oil production and it qulity traits because of increasing the human population. Eight genotypes (Golarchi, Star, Range, DGL, Ayub2000, Hybripol, Lagena and BA0714.) were crossed in Line Tester mating design (5x3). and their F1s were sown in field in RCBD with three replications. Data of 15 F1s and their parents were recorded for various seed yield and yield contributing traits. The data were statistically analyzed for analysis of variance and LT analysis. The ANOVA for combining ability were revealed that the mean sum of squares...
