    Abstract

    Pigeon pea (Cajanus cajan L.) is a vital legume crop known for its role in enhancing the sustainability of agricultural systems, particularly in semi-arid and resource-limited regions. Its ability to fix atmospheric nitrogen through symbiotic association with Rhizobium, by producing nodules should be explored further. The present investigation was carried out with 53 extra-early genotypes of pigeon pea during Kharif 2024 using completely randomized design (CRD) with three replications at ICRISAT, Patancheru. Significant variation was recorded for majority of traits. High GCV and PCV were observed for nodule dry weight followed by total number of nodules. High heritability along with high genetic advance as per cent of mean was observed for days to 50 per cent flowering, total number of nodules and nodule dry weight. The results indicated that higher plant dry weight was associated with higher nodule number and nodule weight along with better morphological traits. Among 53 genotypes studied ICPX 181018-B-SS3-SS1-1-B and ICPX 181028-B-SS22-SS1-1-B were found to have higher mean performance for all the observed characters.
