Variability, heritability and genetic advance in yard long bean genotypes (Vignaunguiculata subsp. sesquipedalis (L.) verdcourt) under polyhouse condition

Thirty yard long bean (Vignaunguiculata subsp. sesquipedalis (L.) Verdcourt) genotypes were evaluated for yield and quality characters under naturally ventilated polyhouse. Polyhouse cultivation helps to protect the crop against biotic (pests, diseases and weeds) and abiotic (temperature, humidity light,) stresses and to ensure round the year production of high-value vegetables. The analysis of variance revealed significant difference among varieties for all the characters studied. High genotypic coefficient of variance, heritability and genetic advance estimated for pods per plant, pod weight and 100 seed weight indicated good scope for their improvement through selection.
