Correlation and path analysis of sorghum [Sorghum bicolor (L.) Moench] germplasm lines

Abstract

This study was performed at Instructional dairy farm, Govind Ballabh Pant University of agriculture and technology during Kharif season, 2017 to evaluate and characterize 96 sorghum accessions for various morphological and fodder yield parameters. A positive and highly significant value of correlation coefficient of component traits ensures the potency of characters for selection procedure in order to maximize fodder yield. Therefore the characters like plant height (cm), stem girth (cm), number of nodes, leaf width (cm), flag leaf length (cm), flag leaf width (cm) and dry fodder yield (g/plant) provides enormous amount of opportunity for selection to improve green fodder yield. Days to flowering, plant height (cm), stem girth (cm), number of nodes, leaf length (cm), leaf width (cm), flag leaf length (cm) and dry fodder yield are the characters which shown to have direct positive effect with the green fodder yield therefore can be used in selection programmes to get the higher fodder yield.
