[Elektronische Daten] [Dragan Milić, Slobodan Katić, Đura Karagić, Jelica Gvozdanović-Varga, Sofija Petrović, Jan Boćanski] The objective of this study was to develop diallel population hybrids by crossing selected germplasm and to determine the gene effects and genetic control of yield and yield components using diallel analysis. A complete diallel including reciprocals was made during 2003 and 2004 between five alfalfa cultivars of different geographic origin. For each pairwise cross, five plants were chosen at random from each of the two cultivars (~100 florets per plant) to obtain the F1 generation. A spaced plant field was established in 2006 which included the five alfalfa cultivars (parents) and their 20 diallel hybrids (F1). The results of the diallel analysis suggest that the genetic control of major agronomic traits is determined by both additive gene action (accumulation of frequency of desirable alleles represented by significant GCA effects) and nonadditive gene action (complementary gene interactions represented by significant SCA effects). This type of gene action expression in alfalfa also determines the way in which breeding is carried out and brings about changes in the methods used and has given rise to the idea of the semi-hybrid breeding of this crop. The concept involves: breeding alfalfas within the population, identification of heterotic germplasm, and the production of seed of the population hybrid (PH).
