甘蓝型杂交油菜制种技术研究──Ⅴ．油研五号制种中角粒数的组成分析赵继献（贵州省油料科学研究所思南５６５１０９）经过对油研五号大面积制种中产量性状的变异分析表明。角粒数的变异比千粒重大，比单株有效角数和单株产量小。对产量的贡献仅次于单株有效角数，与单株...
Study on Seed Production Techniques of Brassica Hybrid Rape ──Ⅴ. Analysis on the Composition of Grain Number in Seed Production of Youyan No.5 ZHAO Jixian (Sinan 565109, Guizhou Institute of Oil Crop Sciences) After analyzing the variation of yield traits in large area seed production of Youyan No.5, Variation of the number of grains is larger than 1000 grains, which is smaller than the effective number of plants per plant and the yield per plant. Contribution to the yield second only to the effective angle of a single plant, and single plant ...
