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。
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.
