To evaluate the factors allowing the sustainable development of Hani rice landrace, rice diversity in Yuanyang County and seed exchange in Qingkou village was surveyed. The results showed that the diversity of rice landraces in Yuanyang County reduced slowly than in other modern culture regions. In terms of altitude gradient...

The interpretation of the geographical patterns of cultivar diversity of rice is the essential basis for their protection. In this study, geographical patterns of cultivar diversity of rice and their correlation with environmental factors and culture of major nationality were investigated using GIS and statistical analysis. The results indicated that...

Agro-biodiversity plays important ecological functions. It is essential for global food production, livelihood security and sustainable agricultural development. Agro-biodiversity is key to the stable, healthy, productive, sustainable field ecosystem and for sustainable management of pests. It has attracted increased attention for the prevention and control of pests based on the...

The rice cropping practices, yields and pest injuries due to pathogens, insects and weeds were surveyed in 106 individual farmers’ fields within two experimental sites (Zhanyi and Xundian counties) in the main rice-producing area of Yunnan Province. The characterization of rice cropping patterns practices and multiple pest injury profiles and...

To determine the genetic diversity and physiological races of the rice blast fungus from Hani terrace of Yuanyang county (Yunnan province), simple sequence repeat (SSR) markers were used to estimate the genetic diversity of isolates of Magnaporthe grisea. Sixty-two isolates were studied for physiological races by using the standard differential...

This article reviewed the situation of ratoon rice in China and summarized the research progresses on ratoon rice yield formation from the perspective of developmental genetics and physiological ecology. In addition, the key cultivation technology and eco-physiological mechanisms of the ratooning plants from low and high rice stubbles were comprehensively...
