1、試驗一Seashorepaspalum新種質(zhì)的植物學特征(胡思源主導,共同完成)試驗二Seashorepaspalum新種質(zhì)的坪用性狀評價(胡思源)1選題背景2010年采集海濱雀稗野生材料1份(暫命名‘T1’),經(jīng)6年馴化栽培和系統(tǒng)選育,認為比其他海濱雀稗具有矮生優(yōu)質(zhì)特性,但缺乏具體和深入了解。獲得轉(zhuǎn)草地早熟禾抗寒基因海濱雀稗材料3份(暫命名‘T2’、‘T3’、‘T4’),需要進一步驗證和了解抗寒性和其他性狀。從美國引進來自12個國家的海濱雀稗種質(zhì)材料48份,國內(nèi)收集6份(Seaspray、Salam、SeaIsle2000、Adalayd2、PureDynacty、SY160904),總計5
2、8份種質(zhì)材料,需要了解和評價其生物學性狀。供試材料及來源PlantNameanditssource編號Item材料登記號Accession植物名稱PlantName來源source11792217922UnitedStates23643681662Mozambique3377709N71-235SouthAfrica,KwaZulu-Natal4509020329-79Argentina5509021342-79Argentina6509022540-79Argentina7509023544-79Argentina8576134Grif5802Brazil9576138Grif5803Bra
