摘要
2002年以云南德钦地区的野生紫花苜蓿的优良无性系、云南昆明地区的逸散种紫花苜蓿优良无性系和引进紫花苜蓿品种(牧歌701、Acrora、GT13R)的优良无性系进行杂交。2006年,2007年对在云南省偏酸性土壤种植的8个杂交种进行了品比试验,对生育期、茎叶比、产草量、越冬性等指标的测定表明,杂交种138、152、196表现优异,可作为优良的候选杂交种。
Alfalfa Cross between Deqin wild alfalfa,a dispersed one named AC-3 in Kunming, and cultivars （Muge701, Acrora and GT13R） were carried out since 2002. And there are eight alfalfa cultivars obtained through testing their yield, overwintering rate, stern to leaf ratio, fresh to dry ratio, disease and pest resistance in 2006 and 2007. The results indicate that the 13,138 and 196 are the best tested alfalfa cultivars to the following work of F2.
