葵花油的价值被人们认识以后,向日葵的种植面积迅速扩大。如何进一步提高产量和质量,仍然是向日葵育种的首要目标。本世纪三十年代,苏联B.C.普斯陶沃依特创造了贮备法育成了一系列含油率高的品种,子实含油率达到38～43％,对提高向日葵油脂产量作出了卓越贡献。然而使向日葵产量大幅度提高则应归功于杂种优势的利用。法国著名向日葵育种家勒克莱尔格,于1964年育成了核型雄性不育系;1969年又育成了胞质型雄性不育系,从而揭开了向日葵杂种优势利用的新篇章。由于杂交种产量高,一般可比品种增产15～30％,秆矮、抗病,生长整齐,适于密植和机械收获,
After the value of sunflower oil is recognized, the area under sunflower cultivation has rapidly expanded. How to further improve the yield and quality is still the primary goal of sunflower breeding. In the thirties of this century, the Soviet Union B.C. Puskuut created a series of stockpile law and law into a series of high oil content of the seed oil content of 38 to 43%, made an outstanding contribution to the increase of sunflower oil production. However, a substantial increase in sunflower production is attributed to the use of heterosis. The famous French sunflower breeder Leclerger cultivated a karyotypic male sterile line in 1964. In 1969, a cytoplasmic male sterile line was bred, opening up a new chapter in the utilization of the sunflower heterosis. Due to the high yield of hybrids, the yield can generally be 15 ~ 30% more than the varieties, short stalks, disease resistance, growth and tidy, suitable for close planting and mechanical harvesting,
