Sažetak
Hungarian vetch (Vicia pannonica Crantz.) is an important forage crop in both central
Turkey (CT) and central European countries. It can be grown in CT as winter crop,
but frequent spring droughts cause yield losses. Our objectives were (I) to investigate
agro-biological variation among populations, (II) to identify useful plant characters
and (III) to develop selection strategies. Forty-five accessions of both var. pannonica
and var. purpurascens were evaluated for the 11 plant characters in 2002/03
cropping season. Var. pannonica was late flowering, had more stems and seeds per
pod, and longer stems and pods. Var. purpurascens had earlier flowering, more days
to physiological maturity, more pods, greater plant biomass and heavier seeds. As
var. purpurascens was early flowering, its longer seed-filling period is likely to
contribute to greater seed size and weight. However, in var. pannonica, late flowering
and ensuing delayed maturity caused strong negative associations between days-toharvest
and other characters. If the earliness, higher biomass and seed size from var.
purpurascens, and the many long stems and long pods from var. pannonica could be
incorporated into one or more genotypes through Mendelian crossings, seed and hay
yields would be substantially increased.
