Pigeonpea [Cajanus cajan (L.) Millsp.] commonly known as arhar, red gram and tur is the second most important pulse crop of India after chickpea. It is. It has been recognized as a good source of vegetarian protein particularly in the developing countries where majority of the population depends on the low priced vegetarian foods. Assessment of genetic variability present in the population and knowledge of association between yield and its components helps in formulating strong selection programme. Correlation studies would provide estimates of degree of association between grain yield and its various components and also among the components. While, path co-efficient analysis further elucidates the intrinsic nature of association of component traits by determining direct or indirect contribution of these traits to yield. Therefore, twenty one genotypes of pigeonpea were evaluated under rainfed conditions at Agricultural Research Station, Ummedganj, Agriculture University, Kota, Rajasthan, during Kharif, 2019-20. In the present study, high heritability accompanied with high genetic gain (GG) was recorded for days to flowering, pods per plant and grain yield. Grain yield was found to be highly significant and positively correlated with plant height, number of branches per plant, number of pods per plant, and test weight in pigeonpea. This indicated that selection for these traits would be effective to improve total grain yield in pigeonpea. In path analysis highest positive direct effect on grain yield was recorded for pods per pant, followed by number of branches per plant. Over all study showed that selection may effective for the pods per plant, branches par plant, test weight, and days to 80% maturity for development of early maturing and high yielding genotypes in pigeonpea.
