河北省油葵品种多点比较试验分析

Multi-site Comparative Tests of Oil Sunflower Varieties in Hebei

为筛选适宜河北省不同生态区的油葵新品种,分别在冀北高寒区张家口市、冀中南太行山浅山丘陵区石家庄市、冀中南太行山前平原区衡水市饶阳县开展油葵品种多点比较试验,对收集到的9个油葵品种的主要农艺性状及产量进行丰产性、稳定性分析。研究结果表明:(1)‘F60’、‘T562’和‘早熟矮大头’的生育期较对照短,其余品种均比对照长。(2)‘新葵23号’和‘新葵7号’比较高大,‘早熟矮大头’相对矮小。(3)‘T562’籽粒较好,百粒重最重,‘HZ001’籽粒小而轻。(4)各参试品种均表现增产,其中‘T562’和‘F60’丰产效应最高。张家口和石家庄‘T562’产量最高;饶阳‘F60’产量最高。(5)‘新葵7号’和‘F60’变异度最低,稳产性最强。‘T562’、‘F60’、‘新葵7号’、‘改良7号’和‘S667’适宜张家口种植,‘F60’、‘早熟矮大头’、‘新葵7号’、‘HZ001’和‘新葵23号’适宜石家庄和饶阳种植。(6)‘T562’、‘F60’综合评价好,‘早熟矮大头’、‘新葵7号’、‘HZ001’和‘新葵23号’综合评价一般,‘改良7号’和‘S667’综合评价较差。

To select new varieties of oil sunflower suitable for different ecological regions in Hebei Province,multi-site comparative tests of oil sunflower varieties were carried out in Zhangjiakou,the high cold region of northern Hebei,Shijiazhuang,the Taihang mountain shallow hilly area in central and southern Hebei,and Raoyang county of Hengshui city,the Taihang mountain piedmont plain of southern Hebei,to analyze the main agronomic traits and yields of 9 oil sunflower varieties for the yielding ability and stability.The results showed that:(1)the growth periods of‘F60’,‘T562’and‘Precocious Dwarf Head’were shorter than that of the control,while the others were longer than that of the control;(2)the plants of‘Xinkui No.23’and‘Xinkui No.7’were tall,and that of‘Precocious Dwarf Head’was relatively short;(3)grains of‘T562’were good,its 100-grain weight was the heaviest and seeds of‘HZ001’were small and light;(4)in terms of production,the yield of all tested varieties increased,among them,the fertility effects of‘T562’and‘F60’were the highest,the yield of‘T562’was the highest in Zhangjiakou and Shijiazhuang,and‘F60’had the highest yield in Raoyang;(5)‘Xinkui No.7’and‘F60’had the lowest variability and the strongest stability;‘T562’,‘F60’‘Xinkui No.7’and‘Gailiang No.7’and‘S667’were suitable for Zhajiakou,and‘F60’,‘Precocious Dwarf Head’,‘Xinkui No.7’,‘HZ001’and‘Xinkui No.23’were suitable for Shijiazhuang and Raoyang;(6)the comprehensive evaluations of‘T562’and‘F60’were good,while those of‘Precocious Dwarf Head’,‘Xinkui No.7’,‘HZ001’and‘Xinkui No.23’were average,and the comprehensive evaluation of‘Gailiang No.7’and‘S667’were poor.
