摘要
油葵具有耐盐碱、耐瘠薄、适应性广等特性,是生物治理及开发盐碱地的首选作物之一,通过油葵优良品种选育,对扩大盐碱地利用及保障粮油安全具有重要的现实性意义。以选育抗盐碱油葵新品种为目标,以自育的细胞质雄性不育系FH030A为母本、恢复系JY009R为父本选育出了抗盐碱油葵杂交种YDF309。2020—2021年参加多点区域试验,2 a 16点(次)平均折合产量为3989.70 kg/hm^(2),较对照品种陇葵杂2号增产12.86%。2021—2022年参加多点生产试验,2 a 16点(次)平均折合产量为4159.12 kg/hm^(2),较对照品种陇葵杂2号增产16.32%。该品种生育期101 d,平均株高166 cm,茎粗2.63 cm,叶片数28片,盘形平,花盘直径20.31 cm,花盘倾斜度4级,百粒重7.20 g,结实率85.40%,出仁率74.0%。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。
Oil-flower has the characteristics of salt-alkali,barren resistance,and wide adaptability.It is one of the preferred crops for biological governance and development of the saline-alkali lands.Breeding high-quality varieties of oil sunflower plays a vital role in expanding land use and ensuring grain and oil security.A new salt-tolerant hybrid variety,YDF309,was developed using the self-bred cytoplasmic male sterile line FH030A as the female parent and the restorer line JY009R as the male parent.From 2020 to 2021,YDF309 was tested in multi-location regional experiments and achieved an average yield of 3989.70 kg/ha across 16 sites over two years,12.86%higher than the control variety Longkuiza 2.From 2021 to 2022,multi-site production experiments showed an average yield of 4159.12 kg/ha,16.32%higher than the control variety Longkuiza 2.This variety has a growth period of 101 days,an average plant height of 166 cm,stem diameter of 2.63 cm,28 leaves per plant,flat disc shape,capitulum diameter of 20.31 cm,disc inclination grade of 4,100-seed weight of 7.20 g,seed-setting rate of 85.40%,and kernel yield rate of 74.0%.It is suitable for cultivation in Jiuquan,Wuwei,Baiyin(Gansu Province),Bayannur(Inner Mongolia),and other similar ecological areas.
