甘兰型油菜属异源多倍体作物,具有生长势强,适应性广,增产潜力大等优点。我国自四十年代引种以来,增产效果显著,目前正在全国各地进一步普及推广。随着甘兰型油菜的发展,大面积单产随之提高,我区油菜品种改革也是这样情况(表1)。品种的不断更新与改革,促进了甘兰型油菜面积的扩大,而甘兰型油菜面积的扩大,又为良种的增产作用创造了更好的条件。随着油菜生产的发展对油菜新品种选育工作提出了更高的要求。根据我们的育种实践,谈几点粗浅的体会:
Brassica napus is a heterologous polyploid crop, with strong growth potential, wide adaptability, yield potential and so on. Since the introduction of China in the 1940s, the stimulation effect has been remarkable. At present, it is being popularized and popularized all over the country. With the development of Brandou type rapeseed, followed by large-area yield increase, rapeseed varieties in our region is also the case (Table 1). Continuously updating and reforming varieties promoted the expansion of Brassica napus, while the expansion of Brassica napus increased the production of improved varieties. With the development of rapeseed production rapeseed new breeding selection put forward higher requirements. According to our breeding practice, talk a few superficial experience:
