Abstract:

Seed industry is the “chip” of agriculture, a landmark and leading project in the construction of modern agriculture, and also a strategic and foundational industry for country. As the largest oil crop in Qinghai Province, rapeseed plays a crucial role in the security of grain and oil in Qinghai Province. It has become a pillar industry for economic development of Qinghai Province and an important channel for farmers to increase their income. Based on the current development situation of rapeseed seed industry development in Qinghai Province, we analyze the main problems and put forward some countermeasures and suggestions to improve the quality and efficiency of rapeseed seed industry in Qinghai Province.

Key words: Qinghai Province, Rapeseed seed industry, Development status, Countermeasures and suggestions
