Harvest index( HI) of Brassia napus L. is relatively low compared to other crops,but significant differences were shown among different varieties. Based on previous studies,the HI of B. napus was restricted byflowrather thansourceandsink. Clarification of the genetic mechanism of high HI in rapeseed provided theories and approaches for high-yield rapeseed breeding. In this paper,we briefly summarized the researches on crop HI around the world,and introduced the progress on rapeseed HI under different envior...

收获指数(harvest index,HI)原名经济系数(co-efficient of economics),指作物收获时的经济产量与生物产量的比值,最早由前苏联学者尼启波罗维奇[1]和澳大利亚学者Donald[2]提出。收获指数反映了作物同化产物在经济产量器官和营养器官上的分配情况,也表示作物光合产物从“源”?
