山东省棉花中熟品种区域试验菏泽点2012年结果分析

The Analysis of Regional Test Results on Mid-variety Cotton of Heze Point in Shandong Province in 2012

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123 d,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产量均居第l位,分别达4813.5、2175.8和2037.0 kg/hm2,增产显著,霜前籽棉产量表现也较好;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124 d,单株果枝数13.2个,单株结铃数25.3个,籽棉总产、霜前籽棉产量、皮棉总产和霜前皮棉产量均居第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。

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 re-sults 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 481 3 . 5 kg/hm2 ,21 75 . 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. CQ1 21 6,CQ1 21 2,CQ1 207,CQ1 21 4,CQ1 21 3,CQ1 21 7 and CQ1 209 were also better. Among the hybrided cotton varieties,ZQ1 223 performed the best,it had 1 24d of growth period,1 3 . 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 1 1 . 36%,1 2 . 46%,1 5 . 05%and 1 2 . 70%comparing with ck,they were all significant-ly higher than those of the ck . ZQ1 233,ZQ1 232,ZQ1 222,ZQ1 230 and ZQ1 225 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 verticilli-um wilt .
