摘要: 【目的】为获得抗旱性强的甘蔗亲本及其衍生品种提供依据。【方法】利用已建立的甘蔗抗旱生理鉴定技术对38个中国常用甘蔗亲本及其衍生品种进行盆栽人工水分胁迫抗旱性评价。【结果】通过聚类和判别分析将其抗旱性分为3类。 【结论】抗旱亲本桂糖11及其衍生的品种云蔗89-351、桂糖89-5表现较强的抗旱性;中高抗亲本CP72-1210和新台糖1号衍生品种的抗旱性取决于另一亲本的抗旱性,与抗旱性强的亲本粤农73-204、湛74-141衍生的品种粤糖93-159、福农95-1702和福农91-4621表现为较强抗旱性,选择不抗旱亲本科5和闽糖69-243组配组合选育的福农91-4710和福农94-0403的抗旱性为中低抗;不抗旱亲本选15衍生的品种闽糖92-505等基本不抗旱。其它亲本种质如斑茅、福农81-745、崖90-33和崖73-512等经鉴定为抗旱种质或亲本。

Abstract: With the established physiological evaluation techniques for drought resistance, thirty-eight commonly used parents and their derived varieties of sugarcane were classified into three groups by cluster and discriminate analysis. Guitang 11 with highly resistance to drought can derive drought-resistance cultivars such as YunZhe 89-351 and Guitang 89-5. The drought resistance in the derived varieties from CP72-1210 and ROC1 with moderate resistance will be dependent on another parent, Yuetang 93-159, Funong95-1702 and Funong 91-4621 derived from the other drought resistant parents (Yuenong 73-204 and Zhan74-141) performed to be resistant to drought, Funong 91-4710 and Funong 94-0403 derived from the water susceptible parents (Ke 5 and Mintang 69-243) to be lowly resistant to drought. The water susceptible parents Xuan 15 and its derived varieties Mintang 88-103 and Mintang 92-505 were all sensitive to water stress, Two Miscanthus clones, Funong 81-745, Ya73-512 and Ya90-33 were resistant to water stress.
