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 (P_1, P_2, F_1, 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 variability.

Transgressive segregation for high and low leaf- stem ratio observed in the cross Kanannado brown × IT93K-205-8 suggests that genes were dispersed among the parents in this study. Polygenic inheritance for the three traits studied was confirmed by unimodality in the F₂ s coupled with the number of effective factors.

Complementary gene effects as evidenced by skewness, epistatic effects were also found. Duplicate gene was predominantly involved in the inheritance.

Introduction

1.1 Background of the Study

Cowpea (Vigna unguiculata (L.) Walp) is one of the most important pulse crops; native to Central Africa and belongs to the family Fabaceae; Cowpea is called vegetable meat due to high amount of protein in the grain with better biological value on dry weight basis (Withanage, 2005).

Cowpea grain on dry weight basis contains 23.4 per cent protein, 1.8 per cent fat and 60.3 per cent carbohydrates and it is a rich source of calcium and iron (Gupta, 1988).

Apart from this, cowpea forms excellent forage and it gives a heavy vegetative growth and covers the ground so well that it checks soil erosion.

As a leguminous crop, it fixes about 70 – 240 kg per ha of nitrogen per year Cowpea is mainly grown in tropical and sub tropical regions of the world for vegetable and seed purpose and to a lesser extent as a fodder crop (Gupta, 1988).
