Abstract:

China is a big producer and a big consumer of rice. Over the past 70 years since the founding of the People’s Republic of China, China's rice industry has made remarkable progress, especially the invention of hybrid rice has provided a strong guarantee for China's grain stability. Under the current new goal of reducing pesticide and chemical fertilizer application in grain production, it is imperative to cultivate new rice varieties with high yield, high quality, strong resistance and wide adaptability. The author introduced the breeding practices of the rice blast-resistant restorer line Minghui 63 and several planthopper-resistant restorer lines.
