Prva srpska sorta ozimog graška za zrno, NS-Mraz

The first local cultivar of winter pea for grain, 'NS MRAZ', was developed by pedigree selection from the hybrid population created by crossing local populations and one French line of pea. The cultivar has a high seed yield potential, exceptional earliness and tolerance to low temperatures. Its average plant height is 75-85 cm; it is of the afila type of pea, tolerant to lodging and of uniform maturity. Its genetic potential for seed yield is more than 7,000 kg ha-1, and it achieved an average seed yield of 5,110 kg ha-1 in three-year trials, while seed yield in production conditions was above 5,500 kg ha-1. Thousand-grain weight is about 200 g, which was the goal achieved in reducing the amount of seed per unit area. Protein yield ranged from 1,100 to 1,200 kg ha-1.Prva domaća sorta ozimog graška za zrno, NS MRAZ, nastala je pedigre metodom selekcije iz hibridne populacije nastale ukrštanjem domaćih populacija i jedne francuske linije graška. Sorta se odlikuje visokim potencijalom rodnosti zrna, izuzetnom ranostasnošću i otpornošću na niske temperature. Prosečna visina stabljike je 75 do 85 cm, afila tipa, tolerantna na poleganje i ujednačenog sazrevanja. Genetički potencijal za prinos zrna je iznad 7 000 kg ha -1 , a u trogodišnjim ogledima ostvarila je prosečan prinos zrna od 5 110 kg ha -1 , dok je u proizvodnim uslovima prinos semena bio iznad 5 500 kg ha -1 . Masa 1000 zrna je oko 200 grama, što je i bio cilj, kako bi se smanjila količina semena po jedinici površine. Prinos proteina kretao se od 1 100 do 1 200 kg ha -1
