外引品种资源虽然大部份在本地区的适应性不强,但可将其有用的性状导入到改良品种中去。如在品质育种中,可充分利用国外无芥酸和低硫葡萄糖甙的品种资源。同时,还可从中筛选适应本地生态环境的品种,改良纯化后为本地生产所利用。为丰富我省的油菜品种资源,加速优质育种进程,促进商品性油菜的发展,70年代以来,我们逐年从国外引入油菜品种,到目前为止,已引入芥菜型品种64份和甘兰型品种111份。1982年开始对这些品种资源进行系统的研究。研究中,在田间设观察圃,播种行数依种子量多少而定,一般播5行,每 Although most of the introduced varieties of resources in the region’s adaptability is not strong, but its useful traits can be introduced into the improved varieties. As in the quality of breeding, can make full use of foreign erucic acid and low-glucosinolate varieties of resources. At the same time, we can also select the varieties adapted to the local ecological environment, improve the purification for local production. In order to enrich the resources of rapeseed varieties in our province, accelerate the breeding process of high quality and promote the development of commercial rapeseed, we introduced rapeseed varieties from abroad one after another since the 1970s. So far, 64 varieties of mustard and 111 Copies In 1982 began a systematic study of these species resources. In the study, we set up observation nurseries in the field. The number of sowing rows depends on the amount of seeds and generally sows 5 lines each
