海南山栏稻品种全生育期抗旱性鉴定与评价
Identification and Evaluation of Drought Resistance of Shanlan Upland Rice in Full Growth in Hainan
摘要
Abstract
To seek out Shanlan upland rice resources with excellent drought resistance,we identified and estimated 22 Shanlan upland rice variations using comprehensive drought resistance assessment system for the whole growth period of upland rice in this study.The results show that,the drought-resistance ability in Shanlan upland rice in Hainan in different growth stages has a significant positive correlation.Shanlan nuo (yellow seed coat) (No.:1,4,6,18,22) showed high resistance to drought in full growth,which is the excellent parental material for breeding new Shanlan upland rice varieties and gene-explore of drought-resistance.Our results indicated that there are rich genetic resources with drought-resistance in Shanlan upland rice in Hainan,which should be pay attention to resource collection,protection and evaluation in this area.关键词
