Abstract

The present field investigation was carried out to evaluate the performance of forty two accessions of yard long bean (Vigna unguiculata L. var. sesquipedalis) for yield and quality attributes. The experiment was laid out by adopting Randomized Block Design (RBD) with three replications and 42 treatments at Grapes Research Station farm located at Anaimalayanpatty, Theni district during summer season of 2023. The per se performance and estimation of variability including phenotypic coefficient of variation and genotypic coefficient of variation, heritability and genetic advance were estimated for the traits viz., days taken for first flowering, days taken for 50 per cent flowering, plant height, pod length, pod girth, individual pod weight, number of pods plant-1 and pod yield plant-1. The genetic parameters for pod length, individual pod weight and pod yield plant-1 were recorded with the highest values. Hence, yield improvement in yard long bean would be achieved through selection based on these attributes.

Conclusion

On the outset, based on per se performance of yard long bean accessions YLB ACC No. 12 followed by YLB ACC No. 15 recorded maximum pod length, individual pod weight, number of pods plant-1 and pod yield plant-1 respectively and showed significant at CD (0.05) level. Hence, YLB ACC No. 12 is concluded has the best performed accession among the all accessions with the traits. In conclusion, individual plants might be selected with traits such as pods plant-1, pod yield plant-1 and individual pod weight based on genetic variability estimates with high levels of heritability and genetic advance.
