Study on the performance of hyacinth bean lines in south-western part of Bangladesh

Abstract

Nine hyacinth bean genotypes HB001, HB002, HB003, HB004, HB005, HB006, HB007, HB008 and HB009 collected from the southwestern region of Bangladesh were investigated at Regional Agricultural Research Station, Jessore during Rabi season in 2008-09 to find out suitable line(s) for cultivation. Leaf length (12.25 cm) and leaf breadth (11.73 cm) of the genotype HB004 were bigger than that of the other genotypes. Smaller leaf size was measured in the genotypes HB003 (7.63 cm x 7.65 cm) and HB006 (7.6 cm x 7.40 cm), respectively. Flower was produced in genotype HB003 at 48 days after planting and genotype HB004 was at 79 days after planting. The longest pod (18.56 cm) was measured from the genotypes HB008 which was statistically similar to HB009 (18.12 cm). The maximum pod breadth (3.87 cm and 3.86 cm) was recorded in the genotypes HB002 and HB003, respectively and the minimum pod breadth (2.30 cm) was observed in HB009. The highest average pod weight (25 g) was measured in the genotype HB002, while the lowest pod weight (11.33 g) was observed in genotypes HB001 which was more or less similar to HB003 and HB006 (12.33 g). The highest number of pods per plant (380) was the highest in the genotype HB004 which was statistically similar to HB005 (374) and the lowest number of pods per plant (143) was in the genotype HB002. The Genotypes HB004 and HB008 produced 6 seeds per pod which was higher than the other genotypes. The highest yield (27.80 t/ha) was obtained from the genotype HB004 followed by the genotype HB005 (26.45 t/ha) and the lowest yield (10.00 t/ha) was measured in the genotype HB006.
