Abstract:
Evaluation of Twelve genotypes of Dolichos bean (Dolichos lablab L.) were done for growth and yield parameters under south eastern coastal zones of Odisha. The results revealed that there was considerable variability existing among the genotypes of Indian bean. Significant differences were also found among the genotypes analyzed for fourteen quantitative characters as well as in seven qualitative characters. The results of the experiment showed that the mean performance of growth parameters at last harvest like plant height, number of compound leaves, number of primary branches per plant, average leaf area, Days to first flowering, Days to 50% flowering were 60.21 to 73.15 cm, 16.20 to 20.07, 3.80 to 7.93, 102.81 to 267.90 cm², 37.20 days to 44.27 days, 42.47 to 48.93 days respectively. The yield parameters viz., Inflorescence length, Number of flowering nodes per inflorescence, Number of pods per inflorescence, Number of pods per plant, Pod length, Pod width, Pod yield per plant, Pod yield in tons per hectare were ranged from, 19.24 to 26.90 cm, 6.13 to 9.53, 5.20 to 9.60, 22.33 to 67.00, 4.20 cm to 13.00 cm, 1.30 cm to 3.10 cm, 0.04 to 0.48 kg and 5.50 t/ha to 13.00 t/ha, respectively. The genotypes 2017/DBB VAR-5 (0.48 kg), 2018/DOL B VAR-2 (0.46 kg) and 2017/DBB VAR-6 (0.43 kg) were found promising for pod yield per plant than other genotypes. These three varieties also showed better growth and yield attributing characters in comparison to other varieties. The genotype 2017/DBB VAR-5 showed variably purple color pods in contrast to rest of the genotypes and can be used in crop improvement programme for developing anthocyanin rich Dolichos bean pods. There is a need to evaluate these high yielding genotypes in larger plots and over multi locations in Odisha for their commercial utilization.
