Prinosi suhe tvari i bjelančevina važan su čimbenik u stvaranju novih kultivara krmnih kultura. Kroz dugi niz godina oplemenjivanja postignut je mali genetski napredak u povećanju kakvoće lucerne. Stoga smo istraživali mogućnost korištenja lokalnih populacija lucerne u svrhu povećanja kakvoće direktnom i indirektnom selekcijom. Dobiven je jak i opravdan utjecaj genotipa i okoline na svojstva prinosa suhe tvari i odnos list/stabljika kao i njihove interakcije na razini značajnosti P<0,01. Najveći koeficijent varijabilnosti je zabilježen kod prinosa vlakana (51,89%), a najmanji kod odnosa list/stabljika (11,74%). Za svojstvo odnos list/stabljika po biljci utvrđen je veliki udio varijance genotipa u ukupnoj varijanci, kao i visoka heritabilnost.Yields of dry matter and protein are important factors in selection of fodder crop cultivars. During the long time of fodder crops breeding for quality alfalfa a small genetic gain was achieved. Therefore we investigated possibility of using local populations of alfalfa to increase quality with direct and indirect selection. Strong and significant influence of genotypes and environments was recorded for yield of dry matter and leaf/stem ratio examined traits and their interactions at the level p<0.01. The highest variation was recorded for fiber yield 51,89 %, while the lowest variation was for leaf/stem ratio 11,74%. For the traits leaf/stem ratio high heritability and high share of genotype variance in total variance were recorded
