为了给甘肃省向日葵产业健康持续发展提供高产、优质、抗病抗逆性强的向日葵品种，酒泉市农业科学研究院以自育不育系XF118A为母本、恢复系FK1421C为父本杂交，对杂交组合进行配合力测定、田间鉴定及考种，选育出食用向日葵杂交种酒葵143。在2018 — 2019年多点区域试验中， 2 a 10点(次)有8点(次)增产，平均折合产量4 095.8 kg/hm2，较对照品种JK601增产8.0%。该品种中熟，生育期113 d，株高204.1 cm；结实率87.6%，籽仁率53.8%；籽粒长锥形，长2.48 cm、宽0.93 cm。籽粒蛋白质含量127.0 g/kg，含油率26.32%。中抗菌核病、黄萎病，高抗黑斑病、褐斑病。适宜在甘肃省河西、中部地区及其他类似生态区春播种植。

To provide high yield, superior and disease-resistant variety in sunflowers, a new edible sunflower variety Jiukui 143, a first-generation edible sunflower hybrid bred from the sterile line XF118A as the female parent and the restorer line FK1421C as the male parent, was bred by Jiuquan Academy of Agricultural Sciences through determination of combining ability, field identification and examination. Data from regional trial with multiple sites carried out in 2018 and 2019 showed that average yield of Jiukui 143(data from 10 sites in 2 years) was 4 095.8 kg/ha, which was 8.0% higher compared with the yield of control, JK601. This variety is a medium-maturing variety, The growth period was 113 d with plant height of 204.1 cm, seed setting rate of 87.6%, seed kernel rate of 53.8%. It shows a long cone grain with a grain length of 2.48 cm and grain width of 0.93 cm. The crude protein content and oil ratio in the seeds were 127.0 g/kg and 26.32%, respectiveluy. It is moderately resistant to bacterial sclerotinia, verticillium wilt, and is highly resistant to black spot and brown spot diseases, It is suitable for spring planting in Hexi, central and other similar ecological areas in Gansu Province.
