摘要:以山东省中熟棉花品种区域试验中常规组和杂交组棉花品种(系)为材料进行生育期、农艺性状、丰产性和抗病性比较试验。结果表明:常规组中CQ1215生育期123d,单株果枝数12.4个,单株结铃数20.10个,籽棉总产居第2位,皮棉总产和霜前皮棉总产均居第l位,产量分别达4813.5、2175.8和2037.0kg/hm2,增产显著,霜前籽棉总产表现也较好; CQ1216、CQ1212、CQ1207、CQ1214、CQ1213、CQ1217和CQ1209等也表现较好。杂交组中以ZQ1223表现最好,生育期124d,单株果枝数13.2个,单株结铃数25.3个,籽棉总产、霜前籽棉总产、皮棉总产和霜前皮棉总产均居第l位,分别比对照增产11.36%、12.46%、15.05%和12.70%。表现较好的有ZQ1233、ZQ1232、ZQ1222、ZQ1230和ZQ1225等。调查显示,所有参试品种均高抗枯萎病,抗或耐黄萎病。

Abstract:The author had comparison tests from growth period, agronomic traits, high-yielding ability and disease resistance which taking the conventional and hybridized groups of regional test of mid-varietycotton in Shangdong as materials.The results showed that the conventional cotton CQ1215 had 123d of growth period, 12.4 of branch numbers, 20.10 bolls per plant. It had the second highest seed cotton yield, the lint yield and pre-frost lint yield were all hightest, which were 4813.5kg/hm2,2175.8kg/hm2 and 2037.0 kg/hm2,they were all significantly higher than those of ck, while the yield of pro-frost seed cotton was also better. CQ1216, CQ1212, CQ1207, CQ1214, CQ1213, CQ1217 and CQ1209 were also better. Among the hybrided cotton varieties, ZQ1223 performed the best, it had 124d of growth period, 13.2 branches per plant and 25.3 bolls per plant.the total seed cotton yield, total pro-frost seed cotton yield,total lint yield and pro-frost lint yield were all had the highest, which increased by 11.36%, 12.46%, 15.05% and 12.70% comparing with ck, they were all significantly higher than those of the ck. ZQ1233, ZQ1232, ZQ1222, ZQ1230 and ZQ1225 were also showed brtter.The investigation results showed that all of the experiment varieties (lines) had high resistance to blight, and resistance or tolerance to verticillium wilt.

农作物品种区域试验是鉴定新品种的丰产性、适应性、抗病性和抗逆性的主要途径,是新品种审定的重要依据。菏泽市农业科学院作为山东省棉花品种区试承担单位,于2012年以山东省棉花中熟常规组和杂交组棉花品种(系) 为材料,在菏泽市农业科学院进行了棉花品种区域试验,总结分析了参试品种的生育期、农艺性状、丰产性及抗病性,以期为棉花品种的选育和品种审定提供依据。

1 材料与方法

1.1 试验材料

供试品种(系)共28个,其中常规组有15个,代号分别为CQ1201(ck)、CQ1202、CQ1203、 CQ1204、CQ1205、CQ1206、CQ1207、CQ1208、CQ1209、CQ1212、CQ1213、CQ1214、CQ1215、CQ1216、CQ1217; 杂交组有13个,代号分别为ZQ1221(ck)、ZQ1222、ZQ1223、ZQ1224、ZQ1225、ZQ1226、ZQ1227、ZQ1228、ZQ1229 、ZQ1230、ZQ1231、ZQ1232、ZQ1233。两组对照品种均是鲁棉研28。

试验地为黏质壤土,肥力较好,耕作层有机质含量1.23%,碱解氮80 mg/kg,速效磷25 mg/kg,速效钾102 mg/kg,地势平坦,地力均匀,排灌方便。……
