中文摘要	通过筛选综合性状较优的小黑麦品种,为半干旱灌区小黑麦杂交亲本的选择提供依据。以从国内外筛选出的30个性状较好的小黑麦品种为试验材料,以石大1号及中饲1048小黑麦为对照,比较参试材料的株高、鲜(干)草产量、鲜干比及其营养成分,并通过灰色关联分析法对参试材料进行综合评价。结果表明,参试材料的株高为104.5~172.0cm;鲜、干草产量及鲜干比分别为44.05~ 69.31t/hm~2,11.54~17.99t/hm~2,3.20~4.43,其中北联5号的鲜(干)草产量均最高,北联3号的鲜干比最高;营养成分方面,北联3号的粗蛋白含量最高,为14.21%,OH1411的中性洗涤纤维及酸性洗涤纤维含量均最低,分别为53.88%和34.49%。综合评价结果表明,北联5号、新疆5号、OH1859、 OH2236、北联3号、826126、HH127、新疆4号及安83-25的综合评价值较高,并均高于2个对照品种,可作为后代选育的杂交亲本。
英文摘要	The study aimed to screen the triticale cultivars with better comprehensive performance and provide the basis for the selection triticale parents in semi-arid irrigated area.Thirty triticale cultivars with good traits selected from China and overseas were used in this experiment,the triticale cultivars Shida No.1and Zhongsi 1048were used as the control.Plant height,fresh,hay yield,the ratio of fresh to dry weight,and nutritional values of these tested materials were studied.The grey relational analysis was used to comprehensively evaluate these triticale cultivars.The results indicated that plant height ranged from 103cm to 172cm;fresh (hay)yield and fresh dry ratio ranged from 9.12%~14.21%,53.88%~62.99%,34.49%~42.46%,respectively. Beilian No.5had the highest fresh and hay yield,while Beilian No.3had the highest fresh dry ratio among all cultivars.In terms of nutritional value,the Beilian No.3had the highest crude protein content(14.21%),while the OH1411had the lowest neutral detergent fiber content and acid detergent fiber content(53.88%and 34.49%,respectively).Comprehensive evaluation showed that Beilian No.5,Xinjiang No.5,OH1859,OH2236, Beilian No.3,826126,HH127,Xinjiang No.4and An 83-25had the highest comprehensive evaluation values, and higher than the two control cultivars,which would be suitable to be planted in Dingxi area and can be used as hybrid parents for offspring breeding.
