Lack of significant growth in the world average yield in upland cotton since 1991 reinforces the impression that the cotton industry has entered into a long梩erm period of slow growth in production. Breeding contribution to the yield growth has sharply decreased, and the result of cotton cultivar performance of regional test displayed that the potentials for the growth of yield in new developed cultivars was delimited, which implies that we must pay more attention to the studies on the diversity of cotton cultivers and genetic mechanism for yield traits.

自90年代初以来，英国及世界的棉花平均产量没有明显得到提高而育种方面对产量的贡献已大大降低；我国的棉花品种区域试验结果也表明，常规品种的增产幅度较低，需要深入研究棉花品种的遗传多样性和产量性状的遗传规律。
