The work entitled "Genetics of agro-morphological yield determinants in mungbean (Vigna radiata L. Wilkzek)" is submitted by Chandra Mohan Singh to award the Ph. D. Degree with specialization in Plant Breeding and Genetics, Rajendra Agricultural University, Pusa - 848 125, Samastipur, Bihar. This work comprised of morphological characterization of mungbean genotypes, genetic variability parameters, correlation, regression, path analysis, multivariate analysis (genetic divergence) using three different methods i.e. Tochers' method, Non-Hierarchical Euclidean method & K-mean clustering method, optimization of harvest index, diallel analysis (graphical and numerical), heterosis, limit of genetic divergence in relation to heterosis, generation mean analysis and inheritance pattern of some important agro-morphological traits.
