饲用苎麻新品种闽饲苎1号的选育

以高产、再生能力强、耐旱、适应性广等的苎麻资源——平和苎麻为亲本,采用钴60γ射线获得的饲用苎麻新品系,经过实生苗种植、优异突变体筛选,初步筛选出平优异株系平和苎麻-2,再经过品种比较试验,最终育成一个产量高、抗逆性好、粗蛋白含量高、宿根性强新品种——平和苎麻-2,2012年正式命名为饲用苎麻闽饲苎1号。在2年5点区试试验中平均年鲜草产量和干草产量分别达138.8t·hm~(-2)和28.0t·hm~(-2),比对照中饲苎1号分别增产32.15%和37.08%,均达极显著水平;闽饲苎1号生产性试验年平均鲜草产量和干草产量分别为140.7t·hm~(-2)和24.7t·hm~(-2),分别比对照中饲苎1号增产18.9%和17.32%,均达极显著水平。

Selective Breeding of New Forage Ramie Variety Minsizhu No.1

The ramie resources (Pinghe ramie) which possessed the characteristics of high yield, strong regeneration, drought resistance, wide adaptability, used cobalt 60 γ to obtain new lines of forage ramie.After seedling planting, excellent mutant screening and variety test, it finally was bred of Pinghe ramie-2 of a high yield, good resistance, high protein content, which officially named as Minsizhu No.1 in 2012.The average annual fresh and dry grass yield were up to 138.8 t·hm-2 and 28.0 t·hm-2 respectively in 2 years and 5 points regional test, increasing 32.15% and 37.08% above Zhongsizhu No.1, the difference reached extremely significant level;The average annual yield of fresh and dry yield of Minsizhu No.1 respectively were up to 140.7 t·hm-2 and 24.7 t·hm-2 in two years productive tests, than control increasing 18.9% and 17.32%, the difference reached extremely significant level.
