河北省参加2010年黄河流域区域试验的中熟棉花品种主要农艺性状分析

摘要

The regional test was the intermediate test between new variety breeding and promotion.The characters of new cotton varieties,such as growth period,high yield and fiber quality could be accurately identified by the regional tests in different ecological environments.The main agronomic characters of 10 medium cotton varieties used to Huanghe River regional test from Hebei Province in 2010 were analyzed in order to provide a basis for variety breeding,variety certification and promotion.The results showed that the growth period of Jijin 1685 was 2 days shorter,that of Shikang 338 and Womian No.2 was 1 day shorter,that of Han 809 and Jifengza No.5 showed the same with CK,that of Nongda 601 and Xipu 3 was 1 day later,and that of Han 6402,Ji H888 and Ji FRH3018 was 2 days later.The yield of Han 6402 and Xipu 3 was higher,and their fiber quality was better.Han 809,Jifengza No.5 and Ji FRH3018 had better fiber quality,but lower yield.Jijin 1685,Shikang 338 and Nongda 601 had common fiber qualities and lower yield.Womian No.2 didn＇t reach the standard.All of the tested varieties were resistant to cotton bollworm and tolerant to Verticillium wilt.Han 809,Shikang 338,Nongda 601 and Womian No.2 had high resistance to Eusarium wilt,Jijin 1685,Xipu 3 and Ji FRH3018 and resistance to it,and Han 6402,Jifengza No.5 and Ji H888 were tolerant to it.%区域试验是新品种选育与推广的中间性试验,通过不同生态环境的多点区域试验,可以正确鉴定棉花新品种的生育期、丰产性和纤维品质等特性。对河北省选育的2010年参加黄河流域区域试验的10个中熟棉花品种主要农艺性状进行分析总结,明确其利用价值,可为棉花品种的选育、审定和推广提供依据。结果表明：从生育期指标看,冀晋1685早熟2 d,石抗338和沃棉2号早熟1 d,邯809和冀丰杂5号熟期与CK相当,农大601和希普3晚熟1 d,邯6402、冀H888和冀FRH3018晚熟2 d;从产量和纤维品质指标看,邯6402和希普3产量水平高且纤维品质较好,邯809、冀丰杂5号和冀FRH3018纤维品质好但产量水平低,冀晋1685、石抗338和农大601纤维品质一般且产量水平低,沃棉2号纤维品质不达标;从抗性指标看,参试品种均为抗棉铃虫、耐黄萎病品种,其中,邯809、石抗338、农大601和沃棉2号高抗枯萎病,冀晋1685、希普3和冀FRH3018抗枯萎病,邯6402、冀丰杂5号和冀H888耐枯萎病。
