摘要： 利用11个小麦新品种（系），对生物产量、收获指数与籽粒产量的关系进行了研究。结果表明，生物产量与籽粒产量的表型和遗传正相关均达极显著水平，收获指数与籽粒产量的表型正相关也达极显著水平。生物产量的遗传潜力及与籽粒产量的密切程度均大于收获指数，说明进一步提高产量的途径应是维持现有收获指数水平，主要通过提高生物产量，协调提高二者之间的关系来实现。

Abstract: The relationship between biological yield, harvest index and economic yield were studied using 11 different new wheat varieties (lines). The results showed that the phenotypic and genetic correlations between biological yield and economic yield were both positive significant at 1% level, the phenotypic correlation between harvest index and economic yield was also positive significant at 1% level. The genetic potential of biological yield and the relationship between biological yield and economic yield were much greater than that of harvest index. The way of increasing economic yield is maintaining harvest index, increasing biological yield and harmonizing the relationship between biological yield and harvest index.
