Abstract:

Taking 16 oil sunflower new cultivars as experimental materials,using a randomized complete block design,the relationship of yield and agronomic characters of each spring oil sunflower were studied.The results showed that the highest yield was CN2007 with 4 954.17 kg/hm2,compared with the CK1,increased by 48.07%,and higher by 80.70% than that of CK2,it showed a significant correlation with the CK1 and CK2,so it recommended for further production test,followed by CN2032,the yield reached 4 295.83 kg/hm2,recommended as a match varieties;agronomic traits of oil sunflower after correlation analysis showed that the main influence factors of yield was the disk diameter,plant height and leaf number,disc weigh,seed setting rate,the number of disk seed,hundred grain weight and stem diameter on yield was positive effect.Therefore,choosing the high yield varieties should pay attention to select the yield and the disk diameter,plant height,leaf number,disc weigh and seed setting rate were high varieties.
