黔油双低2号丰产稳产性及产量构成三要素的通径分析

黔油及低2号系1995年审定的早熟、高产、双低优质油菜品种，为了使该品种在生产上发挥其增产潜力，对该品种丰产、稳产性和产量三要素进行通径分析。分析表明：该品种丰产、稳产性好，单位面积上有效角来数是决定产量的主要因子。为了达到增角增粗增重之高产目的，提出“冬壮春发’”的技术措施。

Analysis of high and stable yield ability of doulbe-low Qianyou 2

Double low Qinagou 2 was examined and approved by Guizhou Provincial Crops Examination Committee in 1995.Due to the rapeseed variety is high yield,premature and quality(low Erucic acid and low glucosinolates) ,we analysedhigh and stable yield alility in the variety.and path analysis of three formation in yieldfactors. The result show that thevariety is high and stable yield. The yield depends mainly on the pods of per unit area. At the same time,point out acultural technology of rearing sound seedling in winter and growing up rapidly in spring.
