CHARACTERS LIMITING PRODUCTIVITY IN Vigna radiata (L.) WILCZEK

Abstract

iwenty four characters at maturity phase of plant growth were studied in 286 green am (Vigna radiata (L) Wilczek) germplasm lines. Variability was large for most of the aracters. Pod yield, biological yield and harvest index were three major determinants seed yield. The harvest index had negative significant association with biological yield id its related characters in late maturing varieties. Vegetative dominance and low arvest index in late group and low biological yield in early and medium groups are the niting factors resulting in low productivity in green gram.
