1994年—1996年度贵州省油菜区试的结果,反映了我省杂交油菜育种近年来在早热高产上有较大进展,尤以位居第一的黔杂185最为突出,还兼具适应性广、稳产性强的特点。分析表明:早熟油菜一旦高产,其稳定性也较强。还分析了不同品质产量构成三因素(单株角果数、角粒数、千粒重与产量构成的主次特点,特别对三因素的变异与产量变异的关系作了分类,不同类型的变异关系特点是提出相应的具有针对性的栽培管理措施的根据之一
The result of rapeseed area trial in Guizhou Province from 1994 to 1996 shows that rapeseed breeding in hybrid rice has made great progress in early heat and high yield in recent years in our province. Especially, Qiaza 185 is the most prominent and adaptable Wide, stable and strong production characteristics. Analysis shows that: once the rapeseed is high yield, its stability is also strong. Also analyzed the quality of the three different factors (the number of fruit per plant, grains, grain weight and yield constitute the primary and secondary characteristics, in particular the variation of the three factors and yield variation were classified, different types of variation relationship Is to put forward the corresponding one of the bases of the cultivation management measures
