向日葵是世界上第二大油料作物,也是我国主要油料作物之一。近年来,我国向日葵在杂交育种上取得了重大进展。1979年吉林省白城地区农科所和辽宁省农科院分别培育出向日葵杂一号和辽葵杂一、二号。我们将这些品种称为中国向日葵第二代品种(广义的品种),而把在此之前的群众品种称为中国向日葵第一代品种。从第二代品种诞生至今,向日葵杂交种的种植面积不断扩大,为发展向日葵生产作出了贡献。然而杂交种向日葵在我国的推广面积,还不到向日葵总栽培面积的20％,远不能满
Sunflower is the second largest oil crop in the world and one of the major oilseed crops in the country. In recent years, China’s sunflower has made significant progress in hybrid breeding.

We refer to these varieties as the second generation of Chinese sunflower varieties (broadly defined varieties), while the previous mass varieties are referred to as the first generation of Chinese sunflowers. Since the birth of the second generation of varieties, the planting area of sunflower hybrids has been continuously expanding, contributing to the development of sunflower production. However, hybrid sunflower in China to promote the area, less than 20% of the total sunflower cultivation area, far from full
