摘　　要：“吉农2号”朝鲜碱茅是以已育成品种吉农朝鲜碱茅为原始材料，用2％的NaCl溶液对其进行盐胁迫，以幼苗生长发育良好为标准进行单株选择，建立无性系形成新品系，并育成新品种。对朝鲜碱茅新品种“吉农2号”的选育经过、选育结果、品种特征、栽培技术和适宜种植区域进行了阐述。吉农2号的产草量高，平均干草产量为4226，63-4346，23 kg／hm2，较对照品种同德小花碱茅增产11，00％-14，02％，且达到显著水平。“吉农2号”于2015年通过全国草品种审定委员会审定，其主要特点是高产、稳产、饲用价值高、耐盐性强、发芽率高，适宜在我国东北、华北、西北地区盐碱地种植。With Puccinellia chinampoensis Ohwi new variety as the raw material, salt stress under 2% NaCl solution was carried out.We se-lected some well-developed seedlings to establish clone forming new lines and to breed new variety Jinong 2.Breeding process, breeding varie-ty and variety characteristics of P.chinampoensis new variety Jinong 2 were introduced; the cultivation technology and proper planting region were reviewed.Jinong 2 has high yield; the average dry grass yield was between 4 226.63 and 4 346.23 kg/hm2 , which increased by 11.00% -14.02% compared with the CK, and reached significant level.Authorized by the national grass evaluation committee in 2015, Ji-nong 2 was a new variety with high and stable yield, high-feeding value, strong salt resistance and high germination rate, which could be culti-vated in the saline-alkali soil of northeast, north, northwest areas in China.
