Meteroglyph Analysis of Cowpea (Vigna unguiculata L.Walp) Elite Genotypes

Abstract

The present experiment was carried out at Director Farm, CCSHAU, Hisar during kharif 2017 to evaluate the performance of 30 selected elite genotypes of cowpea. The variably was studied both within and between groups. The genotypes, KBC 9 and DC 7-15 were placed in the medium fodder-medium grain yield producing group and could be utilized for both, fodder as well as grain production. Moreover, the genotypes (UPC 12-007, KBC-6, KBC-8 and GC 901) were included in high fodder- medium grain yield, which had good potential of grain production as well as excellent potential of fodder production. Likewise, the genotypes (PL-3 Sel., CPD 240 and RC 101) were included in medium fodder-high grain yield, which had good potential of grain production as well as excellent potential of fodder production. It could be utilized for dual purpose after extensive testing over time and space. None of the genotypes was placed in high fodder-high grain yield. So, there is an urgent need to breed for high fodder-high grain so that the maximum fodder as well as grain yield could be obtained simultaneously. Therefore, the hybridization among the diverse genotypes viz., UCP 12-007 (high fodder yield) with PL-3 Sel. (high grain yield) may be suggested for developing dual purpose genotypes through the transgressive segregation.
