Abstract:

Pedigree analysis and the changes of yield traits were studied based on the date of 33 peanut varieties registered in Fujian from 1949 to 2011. The results showed that: 45 varieties were used as parents for peanut breeding, and 22 parents were originated from Fujian, 24 parents were registered varieties. ‘Shitouqi’, ‘Yueyou 92’, ‘Shanyou 523’ ‘Quanhua 10’, and ‘Quanhua 327’ were milestone parent for peanut varieties in Fujian. phylogenetic relationship of varieties mainly came from Guangdong. Systematic breeding was main breeding methods from 1951 to 1980 in Fujian. Since the 1991s, cross-breeding became the main method of peanut breeding. With the replacement of peanut varieties, yield levels were constantly increasing. Gradually increased hundred pods and kernels weight played an important role for peanut production. Fat content increased slightly, while protein content changed in contrast. Plant height decreased, anti-lodging and anti-high fertility capacity improved, and they were suitable for close planting. The total number of branches decreased slightly, while the number of fruit branches was stability.
