山栏稻资源早期抗旱性评价及抗旱资源筛选
Evaluation and screening of drought resistance in shanlan upland rice (oryza sativa) germplasm resource during early growth stage
摘要
Abstract
To confirm drought resistance differences and screen germplasm resources of strong drought resistance ,20 Shanlan upland rice germplasm resources were evaluated and analysed by simulating drought stress using PEG during ger-minating stage and seedling stage .The results showed that the order of drought resistance among germplasm resources was different using different evaluation indexes .There was significant difference of drought resistance among cultivars of Shan-lan upland rice .The drought resistance was significantly positive correlated between germinating stage and seedling stage , drought resistance of L6 ,L30 ,L31 and L33 were stronger at germinating stage ,and that of L6 ,L26 ,L30 ,L31 were stronger at seedling stage .55％ of total resources were above middle drought resistance by subordinate function values analysis ,which indicated that the drought resistance of Shanlan rice resources were strong .L6 ,L30 and L31 were sug-gested to popularize in arid areas .It provide reference for the utilization of drought resistant germplasm resources .关键词
