摘要
Abstract
Fifteen safflower varieties selected among more than 3 000 varieties from 48 countries were evaluated to idendify their drought resistance at dry-hot valley in Yuanmou, Yunnan, China. Their 8 traits such as morphology,phenophase, growth potential, antireversion force and yield were recorded under drought stress. Drought resistance was scored by both drought resistant coefficient (DRC) and drought resistant index (DRI) to evaluate the adaptability of drought, yield stability, and reliability. The results show there was a difference of drought resistance among germplasms,and different impact extents for different characters under drought stress. Some varieties, YN - 9mof, YN - 4mf, and YN - 19mof are the dependable crops with strong drought resistance and good adaption under drought stress, which can be used for new cultivars breeding and production in dry land, since their number of branches, number of fruits per plant,1000-seed weight, yield per plant, and yield per plot were higher compare with control. There are plenty of diversity of drought resistance among safflower germplasms.关键词
