摘要:

抗旱种质资源的鉴定与筛选是抗旱育种的基础。本试验利用全生育期极度干旱法对68份谷子种质资源进行抗旱鉴定,运用模糊数学中隶属法进行综合评价。研究表明,全生育期极度干旱处理情况下,高度抗旱材料较不抗旱材料苗期普遍长势旺盛,部分不抗旱资源出现“卡脖旱”现象；干旱胁迫对穗长的影响大于对株高的影响。结果显示“冀谷37、特早1号、张杂10、张杂11、张杂12”5个品种达到高抗水平,15个品种达到中抗水平,13份材料为弱抗水平,35份材料为不抗材料。

Abstract:

Identification and screening of drought resistant germplasm resources are the basis of drought resistant breeding. In this experiment, the 68 germplasm resources of foxtail millet was screened by the method of extreme drought in the whole growth period, and the fuzzy subordinate function method was used to evaluate the drought resistance. The results revealed that under the extreme drought treatment period, the highdrought resistant materials were more vigorous than the non-drought resistant materials at seedling stage, and some of the non-resistant materials appeared "stuck neck drought" phenomenon. The influence of drought stress on panicle length was greater than that of plant height. The results showed that "Jigu 37, Tezao 1, Zhangza 10, Zhangza 11, Zhangza 12" reached the high resistance level, 15 varieties reached the level of medium resistance, 13 materials were weak resistance, and 35 materials were non-resistant.
