Morphological variation and yield performance of photo-insensitive Dolichos bean [Dolichos lablab (L.) Sweet] genotypes

Abstract

An experiment was conducted during Kharif 2019 at the experimental field of the Dr. PDKV, Akola. to study the morphological variability, yield and yield contributing characteristics among the eight Dolichos bean genotypes viz., AK-WAL-18-15, AK-WAL-18-16, AK-WAL-18-25, DOL-VARK-15-01, DOL-VARK-15-02, DOL-VARK-15-03, DOL-VARK-15-04, Phule gauri and one check Kokan bhushan. The experiment was laid out in a RBD with three replications.The variation for days to 50% flowering ranged from 44.00 days (DOL-VARK-18-02) to 65.66 days (DOL-VARK-18-03). The variation for plant height ranged from 43.67 cm (AK-WAL-18-16) to 71.33 cm (Phule gauri). AK-WAL-18-16 (43.67 cm) was dwarfest one. The variation for number of primary branches/plant had ranged from 3.59 (DOL-VARK-18-03) to 5.52 (Phule gauri). Number of green pods per plant showed variation from 267.06 (AK-WAL-18-15) to 522.23 (AK-WAL-18-16) followed by DOL-VARK-18-01 (520.77). A similar trend was also noticed in green pod yield per plant was registered in AK-WAL-18-16 (5.97 kg) followed by DOL-VARK-18-01 (5.95 kg) and Phule gauri (5.43 kg). Out of eight, four genotypes were significantly superior over the check Kokan bhushan (2.89 kg).
