甘兰型三系杂交油菜自1976年配套成功以来,我省陆续选育出一批杂交组合进行试验鉴定,其中大多数比常规油菜“湘油五号”减产,近两年选育出“湘矮A×619—1”、“湘矮A×135—1”等组合表现比“湘油五号”增产。由于年度间、地域间产量不稳定,从而产生了对杂交油菜的不同看法。有的认为三系杂交油菜有优势,但优势不强,生长一致性差,抗病力弱,适应性不广。有的认为三系杂交油菜年年要制种,费工多不愿推广。为此,我们根据几年试种鉴定结果,对甘兰型三系杂交油菜发展前途谈谈看法:
Since the successful establishment of the three-line hybrid rapeseed in 2007, a number of hybrid combinations have been bred in our province for testing and identification. Most of them have been reduced in output compared with the conventional “ Short A × 619-1 ”,“ Hunan low A × 135-1 ”and other combinations than the“ Hunan oil on the 5th ”increase production. As the annual, inter-regional production is not stable, resulting in a different view of hybrid rape. Some believe that three-line hybrid rape has advantages, but its advantages are not strong, poor growth consistency, disease resistance is weak, and adaptability is not broad. Some believe that the three-line hybrid rapeseed every year, more reluctant to promote more workers. To this end, according to several years of trial identification results, we discuss the future development of three-line hybrid rapeseed Brassica napus:
