Interpretive Summary:

Technical Abstract: Groundnut or peanut (Arachis hypogaea L.) is an economically important crop worldwide as a source of protein and cooking oil, particularly in developing countries. Because of its narrow genetic background and shortage of polymorphic genetic markers, molecular characterization of cultivated peanuts is very limited. Recently two sets of highly informative SSRs developed by ICRISAT (199 SSRs) and the University of Brazilia (66 SSRs) with higher PIC over 0.5 have been reported. The objective of this study is to investigate the genetic variation of the cultivated peanut germplasm in Henan for future breeding studies by using the highly informative SSRs. We have used these markers to genotype 48 peanut popular cultivars and breeding lines representing top producing regions from China (Henan Province and Shandong Province) and USA (Georgia and Texas) and screened out polymorphic genetic markers in these varieties. In the present study, genetic diversity of 128 varieties of peanut germplasm in Henan were studied and their allelic variations in agronomic traits were detected by associated analysis of agronomic traits with the screened highly informative SSR markers. The result could contribute to peanut breeding to improve agronomic traits and marker-assisted improvement of peanut in the future.
