EFFECT OF SELECTION RESPONSE FOR YIELD RELATED TRAITS IN EARLY GENERATION OF FABA BEAN (VICIA FABA L.)

The present experiment was carried out at the research farm of Bhola Paswan Shastri Agricultural College Purnea, Bihar, India, during rabi season of 2022-23 to investigate the selection response for yield related traits in early generations in faba bean.In the current study, genetic interactions were investigated in the F 3 generations of eight faba bean (Vicia faba L.) hybrids.The majority of the traits investigated were positively skewed and controlled by many genes, indicating quantitative inheritance.While in cross combination Bak-1 Bak-20 non-skewed and platykurtic distribution was observed for number of seeds per pod at edible stage.The variance, skewness, and kurtosis of all the crosses indicate high level of heterozygosity.All of the crosses outperformed the parents and the national check in terms of producing high-yielding segregants that demonstrated parental diversity.Pod yield per plant and other associated characters, such as number of pods per plant and number of seeds per pod, are controlled by complementary action of multiple genes.Overall, three lines from each cross with superior pod yield were identified, which could be used for varietal development.
