Abstract

Abstract:

Cold injury is one of the main factors causing yield and quality decline in peanut. Cultivating and planting varieties with high and stable yield and strong cold tolerance is an ideal way to reduce cold injury, However, the lack of high cold tolerant germplasm and the difficulty of cold tolerance identification are the main reasons to limit the breakthrough of cold tolerance breeding. In this study, 72 local peanut varieties in Shanxi province were identified for cold tolerance at germination stage. Based on their relative germination rate and relative germination index, the cold tolerance of 72 peanut cultivars we preliminarily divided the 72 peanut cultivars into five grades, namely high-cold-tolerant type, cold-tolerant type, middle type, sensitive type, and high sensitive type. Ninety pairs of SSR primers with good polymorphism were used to evaluate the peanut cultivars with different cold-tolerance levels, and to examine the genetic diversity of cold-tolerant peanut landraces in Shanxi province making rational and efficient use of cold tolerant peanut resources. The tested cultivars were highly different in genetic diversity and were clustered into three groups with genetic distance of 0.4. Three high-cold-tolerant cultivars and seven cold-tolerant cultivars were clustered into three different groups, indicating that the cold-tolerant peanut varieties are rich in genetic diversity.

Key words: peanut, landraces, cold-tolerance at germination stage, genetic diversity
