2011—2012年,为了对采用γ射线辐射、返回式卫星搭载、高能混合粒子场处理等方法诱变选育的18个紫花苜蓿新品系龙饲1864、龙饲1932、龙饲1963、龙饲2072、龙饲1313、龙饲1902-3、龙饲448-4、龙饲836-9、龙饲435-4、龙饲1333-2、龙饲1228-5、龙饲868、龙饲1243-2、龙饲1310、龙饲1928、龙饲1179-2、龙饲1965、龙饲1998进行品比试验,对其进行了产量和粗蛋白质含量的测定分析。结果表明:龙饲1864连续2年平均产草量居第1位,比其他品系具有明显的优势;龙饲1963粗蛋白含量居首位,可用作提高苜蓿蛋白质含量的育种材料。
From 2011 to 2012, 18 new alfalfa varieties, Longzhu 1864, Longchu 1932, Longjiao 1963, Longchu 2072, were mutagenized and selected by means of gamma radiation, return satellites and high energy hybrid particle field processing. , Dragon feeding 1313, dragon feeding 1902-3, dragon feeding 448-4, dragon feeding 836-9, dragon feeding 435-4, dragon feeding 1333-2, dragon feeding 1228-5, dragon feeding 868, dragon feeding 1243-2 , Longsheng 1310, Longsheng 1928, Longsheng 1179-2, Longsheng 1965 and Longshen 1998. The yield and the crude protein content were measured and analyzed. The results showed that the average grass yield of Longyou 1864 was the first place for two consecutive years, which had obvious advantages over other strains. The crude protein content of Longyou 1963 was the highest, which could be used as breeding material to improve the protein content of alfalfa.
