SUMMARY
The present experiment was carried out at Research Farm, CCSHAU, Hisar during kharif 2015 to evaluate the performance of newly developed 30 genotypes of cowpea under prevailing Haryana agro-climatic conditions. Both within between group variation was studied. The group low fodder-medium grain yield had
maximum genotypes i. e. RC-101, GC-13-1, TC-142, TC-141, PGCP-11, KBC-5, GC-5, Pant lobia-3, while CP-05040, GPCP-28, PGCP-24 and GC-1105 having considerable value for grain yield. However, in low fodder-high grain yield group only one genotype i. e. PGCP-2-3 was placed. It had high value for grain production and could be utilized for cowpea grain production after testing over time and space. The medium fodder-low grain yield producing group included only six genotypes i. e. KBC-6, KBC-8, KBC-7, KBC-9, PTB-1 and DC-16 which could be utilized for further improvement of the fodder yield. However, only three genotypes, viz. KBC-5, Goa Cowpea-3 and GC-901 were included in the high fodder-low grain yield production and could be utilized for cowpea fodder production after testing over time and space. The genotype TPTC-29 was included in medium fodder-medium grain yield and one genotype (GC-1106) was included in medium fodder-high grain yield, which had excellent grain production as well as good potential for fodder production. It could be utilized for dual purpose after extensive testing over time and space.
Key words:Cowpea, meteroglyph analysis, fodder yield, grain yield
