鉴定了半干旱热带地区高产、高适应豇豆杂交有种的改良效果。在不同性状和起源的亲本间进行杂交，杂交后代首先作抗病性筛选，将杂种后代连续种植作栽培评价，以鉴定高产和高适应基因型，进一步评估适应性。筛选出的重组基因型在中西非各种不同半干旱地区生态环境中进一步评估
Identified the improved effect of high yield and high adaptability of the cowpea hybrid in the semi-arid tropical region. Hybrids were made between parents of different traits and origins. The offspring of hybrids were first screened for disease resistance, and the offspring of hybrids were continuously planted for cultivation evaluation to identify high yield and high adaptability genotypes for further evaluation of adaptability. The selected recombinant genotypes are further evaluated in the ecological environment of different semi-arid areas of Central and West Africa
