- 摘要:
- 为促进向日葵新品种龙食葵8号的推广和应用，对其亲本来源、选育过程、特征特性、栽培技术要点等方面进行介绍。龙食葵8号是黑龙江省农业科学院经济作物研究所，以12102A为母本、1604R为父本，选育而成的食用向日葵杂交新品种。2018－2019年，龙食葵8号连续两年在3省9个地区进行区域试验，平均产量2 867.5 kg·hm-2，较对照品种JK108增产9.71%。2021年通过农业农村部非主要农作物品种登记，编号为GPD向日葵（2021）230006。该品种属于中熟品种，生育期103 d，植株直立健壮，株高202.2 cm，茎粗2.83 cm，叶片数32片，籽仁粗蛋白含量25.3%，含油率46.1%。龙食葵8号中抗黄萎病和菌核病（根腐型），中感菌核病（盘腐型）、黑斑病和褐斑病。该品种适宜在黑龙江、内蒙古、新疆等生态相似地区春季种植。
- Abstract:
- In order to promote the cultivation and application of the new sunflower variety Longshikui 8, this study comprehensively described its parental lineage, breeding process, agronomic characteristics and key cultivation technology. Longshikui 8 is a new hybrid variety of edible sunflower bred by the Institute of Industrial Crops, Heilongjiang Academy of Agricultural Sciences with 12102A as the female parent and 1604R as the male parent. During regional trials conducted across nine locations in three provinces from 2018 to 2019, the cultivar demonstrated an average yield of 2 867.5 kg·ha-1, surpassing the control variety JK108 by 9.71%. In 2021, it passed the registration of non-major crop varieties by the Ministry of Agriculture and Rural Affairs of the People’s Republic of China， whith approval number as GPD Sunflower (2021) 230006. This variety belongs to the mid maturity variety, with a growth period of 103 days. The plant is upright and robust, with a height of 202.2 cm, a stem thickness of 2.83 cm, 32 leaves, the protein content of seeds is 25.3%, and the oil content is 46.1%. Longshikui 8 is moderately resistant to verticillium wilt and sclerotinia (root rot type), and moderately susceptible to sclerotinia (disk rot type), black spot, and brown spot. This variety is suitable for spring planting in ecologically similar areas such as Heilongjiang, Inner Mongolia and Xinjiang.
