Abstract
Shandong province is the leading peanut-producing province in China which in turn is the leading peanutproducing country in the world. Shandong Peanut Research Institute (SPRI), an institute ofthe Shandong Academy of Agricultural Science, has had an ongoing breeding program for more than 40 yr and is the source of the peanut cultivars that dominate production in Shandong province and northern China. About 75 peanut cultivars and breeding lines have been released in Shandong by SPRI and other institutions. The genetic base of Shandong peanut cultivars has been described as narrow. The objective of this study was to (a) determine the genetic contribution of main ancestors to the genetic base of Shandong peanut cultivars and (b) study the genetic relationships among the peanut cultivars released in Shandongprovince during 1950-1999. Twentysix ancestors were identified in the pedigrees of 69 improved lines, 24 ancestors of Chinese origin contributed 96.1% of the Shandong peanut genetic base, and two exotic introductions contributed only 3.6%.
