Abstract:
The present investigation entitled “Estimation of genetic variability, heritability and genetic advance in mungbean [Vigna radiata (L.) Wilczek] in summer season under late sown condition” were undertaken to work out genetic variability, heritability and genetic advance in per cent of mean. These carried out during timely sown condition in summer seasons of 2020 at Genetics and Plant Breeding Research Farm of Acharya Narendra Deva University of Agriculture & Technology, Narendra Nagar (Kumarganj), Ayodhya. The experimental materials comprised of 26 genetically diverse varieties/strains and their 88 crosses. The experimental material was evaluated under summer seasons in timely sown condition. The observations were recorded on ten characters. The high estimates of phenotypic and genotypic coefficient of variation (>20%) were found for number of branches per plant, non-reducing sugar, grain yield per plant, harvest index and 100-seeds weight under late sown condition. The characters which exhibited moderate estimates (10-20%) of PCV and GCV were recorded for pod per plant, reducing sugar, seed per pods, TSS, plant height, pod length, biological yield per plant under late sown condition late sown condition. The estimates of heritability in broad sense were high recorded for the all characters and days to maturity moderate in late sown condition. High heritability coupled with high estimate of genetic advance in per cent of mean was not found in late sown condition.
