甘兰型油菜(Brassica napus var.oleifera)是油菜生产上应用最广的一个种,生态类型极为丰富。本研究是在南京秋播条件下以品种的生育阶段组成为主要依据,将不同地理来源的甘兰型油菜代表品种初步划分为前长、匀长、后长及中长等四个生态型。同时对其越冬性,花器官分化,光照反应及主要经济性状进行了研究。这对资源征集,品种应用及高产栽培有一定的参考价值。
Brassica napus var.oleifera is one of the most widely used species in rapeseed production, and its ecological type is extremely rich. This study is mainly based on the composition of the fertility stage under autumn sowing in Nanjing. The representative varieties of Brassica napus from different geographical origins are divided into four ecotypes: pre-length, long-length, long-length and medium-length. At the same time, it conducted research on its overwintering sex, floral organ differentiation, light response and main economic traits. This resource collection, variety applications and high yielding cultivation have some reference value.
