| Abstract: | In order of breeding high yield and good quality grass varieties for lawn, dry seeds of Poa Dratensis L variety Merit were treated by 50 Gy60Coγ radiation,and Nongjing 15 was selected by mutations evaluated by bi oIogical yield, turn green rate,nutritional quality, disease resistance and turf quality. Nongiing 15 was character ized with cold tolerance,saline-alkaline tolerance,strong disease resistance, strong adaptability and high forage value as well. The variety had longer green period, higher hay yield and seed yield than Merit. The average bay yield was 3 832.6 kg hm2 ,and the average seed yield was 510.2 kg hm-2 at mature stage. It was suitable for planting in Heilongjiang province. |
