摘　　要：通过向日葵种质资源筛选及优良新品种选育,加强对盐碱地利用,保证粮油供给安全具有重要的现实意义。以选育高产、优质、抗逆的向日葵品种为目标,用细胞质雄性不育系XW009A为母本、XW009B为保持系,XW09-1R为恢复系,选育出三系杂交种兴沃9号。2015—2016年参加多点区域试验,2 a平均折合产量为4850.94 kg/hm^(2),较对照品种LD5009增产21.64%。2016—2017年参加多点生产试验,2 a 8点(次)平均折合产量4519.54 kg/hm^(2),较对照品种LD5009增产10.50%。该品种生育期122 d,株高223 cm;结实率87.80%,出仁率46.90%;籽粒排列紧密。籽粒蛋白质含量122.0 g/kg,粗脂肪含量285.41 g/kg,含油率30%。适宜在甘肃省酒泉市、武威市、白银市和内蒙古巴彦淖尔市及其他类似生态区种植。The screening of sunflower germplasm resources and the breeding of superior new varieties are of significant practical importance for enhancing the utilization of saline-alkali land and ensuring the safety of grain and oil supply.Aiming to breed high-yield,high-quality,and stress-resistant sunflower varieties,the three-system hybrid variety Xingwo 9 was developed using the cytoplasmic male sterile line XW009A as the female parent,XW009B as keep system,and XW09-1R as the recovery system.From 2015 to 2016,it participated in multi-point regional experiment,which showed an average yield of 4850.94 kg/ha in 2a,an increase of 21.64%compared to that of the control variety LD5009.From 2016 to 2017,it participated in production experiment,achieving an average yield of 4519.54 kg/ha from 8 sites(points)in 2a,which was 10.50%higher than that of the control variety LD5009.This variety has a growth period of 122 days and an average plant height of 223 cm.The seed setting rate is 87.80%,and the kernel yield rate is 46.90%,with seeds arranged closely.The protein content of the seeds is 122.0 g/kg,the ether extract content is 285.41 g/kg,and the oil content is 30%.It is suitable for planting in Jiuquan City,Wuwei City,Baiyin City from Gansu Province,Bayannur City from Inner Mongolia,and other similar ecological regions.
