海滨雀稗新种质植物学特征和农艺性状..docx

试验一Seashore paspalum新种质的植物学特征（胡思源主导，共同完成）试验二 Seashore paspalum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、Pure Dynacty、SY160904），总计58份种质材料，需要了解和评价其生物学性状。供试材料及来源Plant Name and its source编号Item材料登记号Accession植物名称Plant Name来源source11792217922United States23643681662Mozambique3377709N71-235South Africa, KwaZulu-Natal4509020329-79Argentina5509021342-79Argentina6509022540-79Argentina7509023544-79Argentina8576134Grif 5802Brazil9576138Grif 5803Brazirif 5805Brazil1161277112Perurban County ClubSouth Afric-1Bahama 40522BelizrazoriaUnited States, LouisianIN KHUDRAIsraeauna KeyUnited States, HawaiI 10United States, HawaiI 14United States, HawaiI 26United States, HawaiI 32United States, HawaiI 33United States, HawaiI 36United States, HawaiI 39United States, Hawairif 15174ThailanANGILAO GCGuadalaydAustraliaylor 1United States, North Carolinaylor 2United States, North CarolinxcaliburAustralia31647906310-79Argentina32647907561-79ArgentinM3554United States, Georgiemple 1United States, Texaemple 2United States, TexaSP1United States, GeorgiIPV 28-1United States, Georgirif 15190Brazirif 15191BraziaredoUnited States, TexaFP 3-5United States, Georgianibel 3United States, Floridarco 4United States, Floridunia 1United States, HawaiICC (LA)United States, LouisiananctuaryUnited States, FloridDE-2AustraliERTH1Australia49SY160904SY160904海南三亚50SP001Seaspray克劳沃51SP002Salam海南52SP004SeaIsle2000深圳正高53SP006Adalayd-2国内收集54SP007Pure Dynacty克劳沃55SP005T1野生驯化材料56SP008T2转基因材料57SP009
