The NS varieties of forage legumes (lucerne, red clover, pea and vetch) have a satisfying genetic potential for seed yield. However, specific plan morphology leads to extremely great losses in the process of seed production. It is lodging that represents the major problem in the seed production of all forage legumes in the agroecological conditions of Serbia. The seed producers try to delay the beginning of lodging and to decrease its intensity by the regionalization of production and diverse agronomy practices (mode and time of sowing of vetch and pea, the cutting schedule in lucerne and red clover). However the effects of these measures are limited and we thus need the varieties of decreased susceptibility to lodging. Breeders should make an acceptable compromise between forage yield and quality at one side and susceptibility to lodging at the other side. The susceptibility to lodging in forage legumes could be decreased by shortening the internodes and increasing the number of nodes. Increasing the uniformity of flowering in the NS forage legume varieties (especially red clover and vetch) could shorten the period of maturing and significantly decrease seed losses in harvest, thus having a rather positive impact upon the increasement of seed yields.
