人工合成甘蓝型油菜是拓宽油菜遗传育种种质资源的有效途径,也是研究芸薹属物种起源与演化重要的手段之一。对红籽白菜型油菜和黄籽羽衣甘蓝的人工合成杂种进行各种性状调查,研究结果表明:杂种具有亲本互补酯酶同工酶酶带,植株形态相似于甘蓝型油菜,具有较强的营养体杂种优势;植株高度自交不亲和,和几个近缘种杂交亲和性较差,籽粒颜色为红色;杂种和白菜型亲本移栽大田后,同时感染病毒病,但是杂种表现较强的耐病性。 Artificial synthesis of Brassica napus is an effective way to broaden the germplasm resources of rape genetic breeding, but also one of the important means to study the origin and evolution of Brassica species. The results showed that hybrids had the parental esterase isozymes and the plant morphology was similar to that of Brassica napus and had strong nutrition Heterozygotic heterosis. The plants were highly self-incompatible and had less affinity with several relatives, and the color of the seeds was red. After the hybrids and cabbage-type parents transplanted in the field, the viruses were infected at the same time, but the hybrids performed better The disease resistance.
