摘要
本文以欧洲早熟玉米群体选育的十八份自交系为试验材料,对主要农艺性状及大斑病、丝黑穗病的抗性进行分析.结果表明,十八份自交系中大部分材料在主要农艺性状和抗病性方面具有较好的表现.E2106、E2111、E2114、E2116等4份材料在抗大斑病和丝黑穗病方面表现较突出;E2101、E2105、E2112、E2113、E2117等5份材料在产量和抗病性方面表现均比较突出,其中,E2117、E2105等2份材料高抗大斑病的同时,产量分列第2位和第3位,这些材料在今后的育种工作中应着重加以利用;E2109产量位列第1位,但在抗丝黑穗病方面表现一般,在今后的育种工作中应选择性的加以利用.
Abstract
Eighteen inbred lines selected from early maturing maize populations in Europe were used as experimental materials to analyze the main agronomic traits and resistance to major leaf spot and head smut.The results showed that most of the 18 inbred lines exhibited good performance in major agronomic traits and disease resistance.Four materials,E2106,E2111,E2114,and E2116,showed outstanding resistance to Fusarium oxysporum and Fusarium head smut;Five materials,including E2101,E2105,E2112,E2113,and E2117,have shown outstanding performance in yield and disease resistance.Among them,two materials,E2117 and E2105,have high resistance to large leaf spot disease while ranking second and third in yield.These materials should be emphasized and utilized in future breeding work;E2109 ranks first in yield,but its resistance to head smut is average.It should be selectively utilized in future breeding work.
