- Abstract
To provide effective guidance for high yield and good quality of peanut breeding, yield and its rela⁃ tionship with agronomic traits of small-pod high oleic acid peanut cultivar Kainong 1760 was analyzed. The data of regional trials for small-pod peanut varieties in Henan Province in 2014 and 2015 were performed to evaluate the yield and stability of Kainong 1760 based on GGE biplot, and the visual correlation and path analysis were conduct⁃ ed by R language. Results showed that yield and stability of Kainong 1760 ranked the first in both 2014 and 2015. Coefficient of variation of shelling percentage was the smallest. The positive correlation coefficient between full pod percentage and yield was extremely significant. And 100-pod weight, single plant productivity, 100-seed weight, main stem height, lateral branch length, branches number with pods had significant positive correlations with yield. The direct path coefficient of branches number with pods was the largest, indicating that it was the key trait affect⁃ ing yield of Kainong 1760. In conclusion, Kainong 1760 was suitable for large-scale promotion and utilization in Henan Province for its high yield and strong stability. Meanwhile, branch number with pods should be priority con⁃ sideration during breeding practice of new small-pod peanut cultivars.
