| 摘 要： | 为选育优质中晚熟粒用高粱新材料,本试验采用单因素随机区组设计,以4份不同杂交组合高粱亲本为试验材料,分析不同组合杂交种的生育期、农艺性状及产量性状的差异,筛选最佳的中晚熟粒用高粱组合。高粱组合杂交种的生育期存在差异,但相差不大,生育期最长的高粱组合23A×014-52,生育期为134天,生育期最短的高粱组合147A×014-34,生育期为123天;高粱组合23A×014-52的农艺性状较好;与对照相比,增产的高粱组合为23A×014-52、27A×017-95,其中高粱组合23A×014-52增产明显,较对照高出30.06%。结合分析农艺性状、产量性状等,高粱组合23A×014-52杂种优势较突出,可以作为培育中晚熟粒用高粱的亲本材料。

| Abstract: | To breed high-quality and middle-late maturing grain sorghum, the authors used single-factor randomized block design, took the hybrids of four different sorghum combinations as test materials, to analyze the difference of agronomic traits and yield traits and screen the best combination of middle-late maturing grain sorghum. There were difference of the growing period of hybrids from tested combinations, but the difference was not obvious, the hybrid sorghum combination 23A×014-52 had the longest growing period about 134 days, the hybrid sorghum combination of 147A×014-34 had the shortest growing period of 123 days; the agronomic traits of sorghum combination 23A×014-52 were relatively good; the yield of the combination 23A×014-52 and 27A×017-95 were higher compared with that of control, and the yield of the combination 23A×014-52 was 30.06% higher than that of control. Considering the analysis of agronomic traits and yield traits, the sorghum combination 23A×014-52 has strong heterosis and could be used as parent material for cultivating middle-late maturing grain sorghum. |
