一、研究目的优良品种胜利油菜自1955年起在全国油菜主要产区全面推广,群众普遍表示欢迎,華中区湖北、湖南、江西三省都获得高产记录,但本品种成熟期较迟,一般比本地早中熟品种迟熟10—15天,迟熟的原因,除由各个生育階段进行分析外,本品种开花习性生物学的研究,对进一步了解该品种的生物学特性,揭发其开花期长短与成熟期迟早的关系,不仅在理论上有重大意义,而且在生产上推行群众性选种留种工作可以提供科学根据。根据1954年—1956年華中农学院和華中农科所两年间观察,胜利油菜可以分为三种类型:
First, the purpose of research Excellent varieties of rapeseed rape since 1955 in the main rapeseed areas across the country to promote the general public welcomed the Central Plains Hubei, Hunan, Jiangxi provinces have access to high-yield records, but the varieties mature later, generally than the local Early maturing varieties of late maturity 10-15 days, late maturity reasons, in addition to the various stages of growth analysis, the varieties of flowering habits of biological research to further understand the biological characteristics of the breed, revealing the flowering period of its length and The relationship between maturity and early maturity is not only of great theoretical significance, but also provides scientific basis for promoting mass selection and seed-saving work in production. According to two years between 1954 and 1956, Huazhong Agricultural College and Huazhong Agricultural Science Institute observed that Shengli canola can be divided into three types:
