A Systematic Analysis for Grouping Greek Peanut (Arachis hypogaea L.) Germplasm Based on Eight Important Phenotypic Traits

S.T. Kotzamanidis, N. Stavropoulos and C.G. Ipsilandis    

Abstract: An extensive evaluation of 43 varieties from the Greek collection of groundnut was carried out during years 1986-90 in the farm of the Cotton and Industrial Plants Institute, Greece. A systematic characterization referred to eight botanical, morphological and agrophysiological traits included in the descriptor lists of IBPGR and ICRISAT, followed field evaluation. These traits were: growth habit, branching pattern, leaf colour, pod distance from the main root, synchronized pod maturity, days to emergence, days to 50% flowering and days to maturity. Principal Component Analysis (PCA) extracted two main factors representing 83% of the total variation. PC1 (interpreted as earliness factor) explained 68.4% and PC2 (interpreted as synchronized maturity factor) 14.6% of the total variance. Cluster analysis classified the assessed cultivars into distinct groups on the basis of earliness and synchronized pod maturity. The evaluation has shown that most of the Greek varieties botanically belong to the subspecies hypogaea and to Virginia type which is late material. Only a few varieties belong to the subspecies fastigiata and to Valencia or Spanish type and found to be an early genetic material. The evaluation also contributed in identifying certain varieties, such as Serraiki, Sakania Sindu and Poroia, as promising for their significant earliness, varieties Tragana, Ispaniki and Proimi Funtoti for high pod concentration and varieties Krestena, Karolina and Lakonia for highly synchronized pod maturity.
