蚕豆产量研究与高产育种

Yield Analysis and High Yield Breeding of Faba Bean( Vicia faba L.)

对近30余年蚕豆(ViciafabaL.)产量研究与高产育种技术进行了总结,蚕豆产量研究表明:生物学产量是经济产量形成的物质基础,两者间存在高度正相关;产量构成因素对产量的形成均有较高的正向作用,但产量构成因素的改良受单株荚、粒数与粒重间负相关的制约;收获指数与籽粒产量间呈现极显著的正相关。还对蚕豆高产育种中高结荚率、早熟性的选择以及如何协调荚、粒数与粒重间的关系进行了讨论。

Yield analysis and high yield breeding of faba bean( Vicia faba L.) in the latest 30 years were reviewed.The results of faba bean yield analysis showed: (1)Biological yield was the basis of economic yield,and the relationship between them was very high and positive;(2)Yield components acted positively to yield but the improvements of yield components were restricted by the negative relationship between the number of pods or kernels and kernel weight;(3) Harvest index was stable and significantly positively related to yield. Selection of high pod setting ratio and early maturity and how to coordinate the relationship between number of pods or kernels and kernel weight in high yield breeding of faba bean were also discussed.
