Inheritance Of Grain And Fodder Yields And Yield Components In Cowpea (Vigna Unguiculata (L.) Walp).

📄 Project Abstract

Studies were carried out on Two landraces Kanannado Brown and Biu Local (Fodder types) and IT98K-205-8 (grain type) to estimate the gene effects for grain and fodder yields and yield components in cowpea, using generation mean analysis. Six generations were developed (P1, P2, F1, BC1 P1,BC2 P2 and F2) and evaluated at Kadawa. Data collected were analyzed for: gene segregation, gene action governing the three key parameters (leaf-stem ratio, total biomass and dual trait) as well as heritability. Significant mean for leaf-stem ratio in the crosses Kanannado brown × IT93K-205-8 and in the Biu local × IT93K-205-8, and for dual trait in the cross Biu local × IT93K-205-8. All the backcrosses had significant better mean performance for all the parameters. This indicated that backcross breeding procedure may be important in the improvement of yield in cowpea. Different means obtained showed by the individuals in the population was an indication of the presence of considerable amount of genetic...
