Abstract

Sixteen cultivars of blackgram were studied for assessing the association between yield and its component characters. A significant positive association existed between seed yield and all the yield components studied. The co-heritability estimates between the various pairs of characters indicated that the strength of association of all other characters with height of plant is high as against the association of them with branch number. The path analysis showed that two characters namely the height of plant and cluster number have a direct effect as well as indirect effect via. other characters on seed yield, while branch number, pod number, pod length and seed number per pod have either very low positive or high negative, direct or indirect effects on seed yield. As such the height of plant and cluster number are important yield components to be considered.
