The First Peanut (Arachis hypogaea L.) Crosses in Greece and Transgressive Segregation on Yield Characteristics of Pedigree Selected Accessions

S.T. Kotzamanidis

Abstract:
The first peanut crosses ever tried in Greece were performed over two growing seasons (1985 and 1986). The 13 successful crosses in 1985 belong to the following crossing schemes: VirginiaxSpanish, VirginiaxValencia, ValenciaxVirginia, VirginiaxVirginia, ValenciaxValencia and ValenciaxSpanish. The 7 successful crosses in 1986 belong to 2 crossing schemes: VirginiaxValencia and VirginiaxVirginia. It resulted that in the climatic conditions of Greece a higher percentage of success can be achieved (16%), when the crosses are realized as early as possible so that the high summer temperatures can be avoided. Also, the transgressive segregation for yield characteristics of 100-pod weight and 100-seed weight was studied during the years 1985-1990 in the Cotton Research Institute. Pedigree selection was applied from the F3 to F5 generation and segregated materials together with the parental varieties were evaluated. Most of the selections that showed transgressive segregation belonged to the cross type VirginiaxSpanish. Data indicated that yield and quality of peanuts could be improved by exploiting the phenomenon of transgressive variation occurring principally in crosses between varieties that belong to peanut types Virginia and Spanish.
