Field pea for dry grain and fodder is being bred in Osijek (Croatia) since 1987, but this work is intensified since the year 1997. Comprehensive variety trials are being conducted each year since 1997. Varieties of various origins were evaluated. Also they were used for investigation of yield and yield components interaction with aim to define the primary selection objectives. Old varieties were used to select the breeding lines too. In the year 1997 there were only 5 registered varieties of field pea for dry grain in Croatia, all of foreign origin, and only 8 fodder varieties; only one of them was of Croatian origin. Collection of parental lines is being continuously enriched with introductions of divergent varieties and accessions of ecotypes and wild relatives. Breeding lines and accessions are being utilized in a new variability creation which is followed by selection, mostly pedigree. Most important breeding goals are high yield and quality of grain and fodder and resistance to biotic and abiotic stresses. The results of numerous hybridizations and selection are two registered pea varieties: winter fodder pea Osjecki zeleni (2002) and spring dry pea Gold (2005), created in collaboration of Agricultural Institute Osijek and Faculty of Agriculture in Osijek. Also, there are three genotypes that are currently being tested by Seed and Seedlings Institute in multi-location state trials. Two of them are of dry pea type and one is fodder type. In two previous years of state trials, both dry pea genotypes yielded better than standard. Average yield of our new genotype in 2006 was 4.6 tonnes per hectare while standard yielded 4.3 tonnes per hectare in average. In 2007 our new genotype average was 5.7 tonnes per hectare while standard yielded 4.7 tonnes per hectare in average. Thus our new genotypes have demonstrated their high yielding potential.
