EVALUATION OF COMMON BEAN GERMPLASM COLLECTED FROM THE NEGLECTED POCKETS OF NORTHWEST PAKISTAN AT KALAM (SWAT)

AMANULLAH^* AND ASIM MUHAMMAD

Abstract: An experiment consisted of 33 germplasm of common bean (Phaseolus vulgaris L.) collected from FATA (Federally Administered Tribal Areas) and neglected pockets of Khyber Pakhtunkhwa were evaluated at the sub-Research Station, Kalam (Swat) during summer 1999-2000. Based on the grain yield potential, these germplasm were divided into three groups. Germplasm CB-9 ranked first by producing maximum grain yield of 3310 kg ha^-1, while germplasm CB-6 with 3188 kg ha^-1 ranked second, while the lowest grain yield (333 kg ha^-1) was produced by germplasm CB-23. Average grain yield in groups decreased in descending order from 2701 kg ha^-1 in group I to 1553 kg ha^-1 in group II and then further decreased to 750 kg ha^-1 in group III. Maturity period varied from 76 to 96 days, plant height 39 to 96 cm, branches per plant 4 to 7, pod length 5.7 to 14.3 cm, seeds per pod 4.9 to 7.6, pods per plant 9 to 39, dry matter yield 1334 to 6666 kg ha^-1, 100-seeds weight 19.0 to 72.1 g, and harvest index varied from 14.3 to 66.2% among different germplasm. Average values of grain yield in the three groups showed positive relationship with plant height, dry matter yield, and harvest index; but showed negative relationship with days to maturity.
