Identification of potential agronomic lines among Nigerian pigeonpea (Cajanus cajan L. Millsp.) accessions for crop improvement

Pigeonpea (Cajanus cajan (L.) Millsp.) is a grain legume crop from the tropics and subtropics cultivated for its highly nutritious seeds. Relatively low yields have been observed among African accession with little information on germplasm performance. Therefore, it needed to identify resilient germplasm, varieties or accessions improve agronomic This study assessed morphological variability selected of Nigerian pigeonpea potential lines improvement. A total 52 were evaluated using 10 qualitative 13 quantitative traits. They planted completely randomised design. Yield performance, trait correlation, principal component (PC), cluster analysis used breeding lines. The revealed wide both pigeonpeas clustered into three major groups. Four components eigenvalue > 1 accounted 68.95% variation observed. first PC 30.13% yield components, which include days 50% flowering, plant height, maturity, vigour at flowering as contributors. These traits also showed strong significant correlations between themselves. Hence, they can be improved simultaneously. identified several based performance that multilocational evaluations
