Insights from Morpho-Physiological Traits Imparting Tolerance for Preharvest Sprouting of Mungbean Genotypes

Abstract

Due to the absence of fresh seed dormancy (FSD) in mung bean seeds makes them susceptible to pre-harvest sprouting (PHS). Mung bean yield has been proved to be 60–70% reduced in response to PHS, an abiotic stress. By understanding this problem present study was carried out at at experimental field, Department of Agricultural Botany (Plant Physiology) (20.70060N, 77.03710E), PGI, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during kharif (rainy) season 2012-13. The experiment entitled “Insights from morpho-physiological traits imparting tolerance for preharvest sprouting of munbean genotypes”. The design of experiment is Randomized block design in three replications with sixteen genotypes. It was observed that on the basis of morpho-physiological traits viz., high hard seed %, pod pubescence, lower germination in pod and seed, less seed and pod moisture genotype AKM-9801, AKM-9907, BM-2002-1 and AKM-10-05, genotypes were found to be tolerant to preharvest sprouting. And more interesting fact is the seed yield per hector found efficient in AKM-8802 and AKM-9907. So, it was found that AKM 9907 is best suitable variety of mungbean in kharif season to prevent crop from whether damage and improve yield also.
