摘要
连续2年种植29个德国引进黑麦草Lolium spp.品种,以Tetragold和野生黑麦草为对照,综合评比各黑麦草品种的分蘖力、株高、植株鲜质量、抽穗期和成熟期等生长性状,筛选性状优良、在四川具有较强适应性的黑麦草品种。结果表明:Taurus、Barfort、Gemini、Fastyl 4个黑麦草品种表现出优良的综合生长性状,在四川地区适应性强,可用于引进品种推广应用研究;Licarno、Bartissimo、Alamo拔节速度快,抽穗前植株较高,Tosca、Zarastro、Remy分蘖力强,Lolita植株鲜质量产量高,Defo、Prestyl、Pomerol花期迟,生育期、供草期长,可作为选育当家品种的远缘优良亲本材料。
29 introduced German ryegrass varieties were grown for two years to select adaptable ones in Suehuan compared with Tetragold and wild ryegrass, according to tillering, plants height, fresh biomass, growth characters at booting and maturity stages. The result indicated that variety Taurus, Barfort, Gemini, Fastyl had better comprehensive growth characteristics and could be used and extended in Sichaun. Licarno, Bartissimo and Alamo had fast jointing speed and higher plant height before heading; Tosea, Zarastro, Remy had strong tillering; Lolita showed high fresh biomass; Defo, Prestyl, Pomerol displayed late flowering and maturity, and could be used as parental materials for breeding.
