Genetic gain in yield and agronomic characteristics of cowpea cultivars developed in the Sudan Savannas of Nigeria over the past three decades
This paper evaluates a field study conducted to determine the rate of genetic improvement in grain and fodder yields and associated agronomic and physiological changes of determinate and semi-determinate cowpea genotypes developed in the Nigerian Sudan savannas from 1974 to 2004.
Improvement in grain and fodder yields of cowpea genotypes representing four decades of breeding in the Nigerian Sudan savannas
This paper presents the findings of a field study conducted to determine the rate of genetic improvement in the grain and fodder yields of cowpea genotypes developed in the Nigerian Sudan savannas from 1970 to 2004.
