Screening Varieties of Phaseolus vulgaris for North Coastal Andhra Pradesh

Key Points

CTP-1 achieved the highest yield of 15.87 t ha-1, outperforming other varieties in the trial.
Analysis revealed significant traits such as pods per plant and test weight positively correlate with yield.
The field experiment spanned three years (2002-2004) and involved 12 Phaseolus vulgaris varieties.
These findings suggest that selecting for specific traits can enhance rajmah yields in coastal regions.

Abstract

A field experiment was carried out for three consecutive years (from 2002-2004) at RARS, Chintapalle, A.P. to screen a suitable Rajmah variety for agency areas of North Coastal Andhra Pradesh. Among the 12 entries studied, CTP-1 was found to be the best with highest values for no. of pods per plant (7.31), pod length (11.57 cm), test weight (42.33 g) and the yield (15.87 t ha-1) followed by PDR-188 (13.22 t ha-1). Studies on character association revealed a positive association of pods per plant, seeds in a pod and the test weight with the yield indicating the importance of these traits for selection in French bean.
