油用向日葵杂交种YDF309 选育报告
Breeding Report on the Oil Sunflower Hybrid YDF309
摘要
Abstract
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 3 989.70 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 4 159.12 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.关键词
