Evaluation of Pre-harvest Sprouting Resistance of Major Barley Resources in Yunnan Province
摘要
Abstract
To identify and screen the highland barley germplasm resources with resistance to pre-harvest sprouting in Yunnan Province,this study conducted whole-spike germination tests,seed germination tests and dormancy period identification on 36 highland barley resources.Data analysis methods such as pre-harvest sprouting resistance grading,average membership function and cluster analysis were used to evaluate the pre-harvest sprouting resistance.In the spike germination resistance classification experiment and whole-spike germination test,the 36 hulless barley(Hordeum vulgare L.var.nudum)materials exhibited significant variations in both spike germination rate(ranging from 4.17％to 100.00％)and spike germination degree(2.50％to 88.94％).The grain germination rate displayed a similar broad variability spectrum(4.00％to 100.00％).The membership function average values for comprehensive evaluation of sprouting resistance ranged from 0.087 6 to 0.800 0.The comprehensive evaluation results showed that among the 36 highland barley materials tested,13 materials with better resistance were screened out,including 1 highly resistant material(Yunqing 602),3 resistant materials(Yunke No.4,Chuan 12259,20QK-97),and 9 moderately resistant materials(Yundamai No.12,Dianqing No.1,Dianqing No.2,Dianqing No.3,Diqing No.6,Zhongdian short white highland barley,15YD-3,20QK-5,20QK-3),which can provide valuable materials for future highland barley pre-harvest sprouting resistance breeding in Yunnan Province and a reference method for subsequent screening of resistant resources.关键词
