摘 要: | 本文将所研究的12个性状归纳成黄籽外显率、分枝状态、主花序状态和产量性状4组.典型变量分析结果指出,黄籽外显率与任一性状组间,在关联上起作用的主要是百株外显率和重量百分比.但后者较难考察.随着黄籽外显率的提高,植株长势减弱,受影响最大的性状有:主花序状态、每角粒数和二次有效分枝数.

STUDIES ON THE RELATIONSHIP BETWEEN YELLOW SEED PERCENTAGE AND AGRONOMIC CHARACTERS IN RAPESEED |
| |
Abstract: | The relationship between yellow-seed percentage and related agro-nomic characters was studied in 11 rapeseed (B. Campestris) cultivars(lines). The 12 characters were grouped into yellow-seed percentage,branch status, characters of inflorescence on main stem, and yieldcomponent. The canonical variable analysis indicated that the importa-nt effect on the basis of relationship between yellow-seed percentageand other groups was yellow-seed plant percentage and yellow-seedweight percentage, but the latter is a trouble to measure. The plant withlow yellow-seed percentage generally grew prolifically. These mostlyaffected the characters of inflorescence on main stem, average numberof seed per pod, number of secondary branches containing at least onefull developed pod. |
