1、试验一Seashorepaspalum新种质的植物学特征（胡思源主导，共同完成）试验二Seashorepaspalum新种质的坪用性状评价（胡思源）1选题背景2010年采集海滨雀稗野生材料1份（暂命名‘T1’），经6年驯化栽培和系统选育，认为比其他海滨雀稗具有矮生优质特性，但缺乏具体和深入了解。获得转草地早熟禾抗寒基因海滨雀稗材料3份（暂命名‘T2’、‘T3’、‘T4’），需要进一步验证和了解抗寒性和其他性状。从美国引进来自12个国家的海滨雀稗种质材料48份，国内收集6份（Seaspray、Salam、SeaIsle2000、Adalayd2、PureDynacty、SY160904），总计5
