在研究冬播甘兰型油菜品种间杂种时,发现杂种的叶簇在秋季比亲本类型经常表现出强大的优势。根据这一点提出了利用叶簇的优势指数来选择具有优势籽粒生产杂种可能性的假说。
In the study of inter-specific hybrids between winter rapeseed rape cultivars, it was found that the hybrid leaf clusters often showed a strong advantage over the parental types in the fall. Based on this, a hypothesis of using the dominant index of leaf clusters to select the possibility of hybrids with superior grain production was proposed.
