Abstract:
Fifteen greengram (Vigna radiata L.) genotypes were evaluated for physiological traits in a field experiment conducted during kharif season 2021- 2022 at Sorghum Research Station, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. Observations were recorded on 20^th, 40^th, 60^th DAS and at harvesting stage. Results revealed that the highest mean leaf area per plant were 143.04, 558.72, 610.67 and 462.03 in genotype BM-21-1 on 20 DAS, 40 DAS, 60 DAS and at harvest stage respectively. Highest mean leaf area duration was 31.40 recorded in greengram genotype Phule M-504-20-27 at 41-60 DAS compared to rest genotypes of greengram. Mean leaf area index (LAI) was highest in Phule AKM-1606 (0.23) on 20^th DAS, 1.48, 1.73 and 1.44 were recorded in 40^th, 60^th DAS and at harvest respectively. Highest mean chlorophyll content (SPAD Reading) was 71.10 recorded in genotype BM-21-1 among other at harvest stage. Mean shoot biomass (g) varied from 0.09-18.23 grams in different genotypes of greengram. Significantly highest mean shoot biomass was observed in genotype BM-21-1compared to rest genotypes of greengram. Mean root biomass highest showed by genotype BM-21-1, 2.37 at harvest stage. These results not only provide valuable insights into the natural variations present in mungbean populations but also emphasize the importance of choosing and breeding genotypes with specific physiological traits to improve the overall performance and yield of crops.
