Abstract:
The present investigation entitled “Dormancy studies in in-situ Germination in Mungbean (Vigna radiata L.)” was undertaken to study the Dormancy in Mungbean, at Department of Agricultural Botany, VNMKV, Parbhani during Kharif 2020 and Kharif 2021. The experiment arranged in Randomized Block Design (RBD) with two replications all 34 treatments has four rows of 4.5 meter long with 45 cm distance in between rows. The experimental material included in the present study was 34 entries including 9 checks. Morphological characters viz., days to 50% flowering, days to maturity, days to shattering, plant height (cm), number of primary branches, seed yield per plant (g) whereas, seed quality parameters on germination (%) and time to opening pod (hrs) were recorded. The observations on field level were taken on five randomly plants for all the quantitative characters except days to 50% flowering, days to maturity and days to shattering which were taken on whole plot basis and laboratory work completed in the Laboratory of Seed Technology, Department of Agricultural Botany, VNMKV, Parbhani. The statistical analysis of data was carried out as per the standard method. The seed quality parameter i.e. germination percentage, among all the tested genotypes and checks observed range of germination percentage from 73.5% to 94.3% after harvest. Among the genotypes in pooled mean, Phule M 818-8 recorded highest germination percentage followed by AKM-1605 and Phule M 817-13 while TBM-6 recorded lowest germination percentage. On the basis of pooled mean, trait for time to opening the pods, genotypes AKM-1603, AKM-1602 and TBM-4 taken very short time to open the pods. These genotypes required nearly half day to open the pods, means these were found favorable in in-situ germination which indicates that these are less dormant genotypes. This study revealed that the dormancy of the Mung bean is indicated by the method of measuring the time of opening the pods by in-situ germination.
