以16个油葵新品种为试材,采用随机区组设计,研究了各油葵品种的产量以及农艺性状间的关系。结果表明:CN2007产量最高,达4 954.17kg/hm2,比CK1增产48.07%,比CK2增产80.70%,与CK1和CK2均存在显著性差异,建议进一步进行生产试验;CN2032次之,产量达4 295.83kg/hm2,推荐作为搭配品种;经过油葵主要农艺性状的相关分析表明,对油葵产量影响最大的因素是盘径、株高和叶片数,盘粒重、结实率、花盘粒数、百粒重和茎粗对产量也是正向影响;因此,在高产品种的选择上要注意选择产量和盘径、株高、叶片数、盘粒重、结实率都高的品种。
Sixteen new oil sunflower varieties were used as experimental materials. The randomized block design was used to study the relationship between yield and agronomic characters of each oil sunflower variety. The results showed that CN2007 had the highest yield of 4 954.17kg / hm2, 48.07% more yield than CK1 and 80.70% more yield than CK2, which was significantly different from CK1 and CK2, and further production test was recommended. CN2032 was followed by 4 295.83 kg / hm2, which is recommended as a matching variety. The correlation analysis of the main agronomic traits of oil sunflower showed that the most influential factors on the yield of sunflower were the diameter, plant height and number of leaves, weight of panicle, seed setting rate, Grain weight and stem diameter also have a positive effect on yield; therefore, we should pay attention to the selection of varieties with high yield and variety, including yield and diameter, plant height, leaf number, panicle weight and seed setting rate.
