摘    要:探讨一二年生棉花耐冷相关性状的种间杂种优势和细胞质效应,为棉花耐冷杂交育种提供理论依据.采用随机区组设计,对由4个不同耐冷级别的棉花材料配制的4对正反交组合F1进行株高、茎粗、出苗至开花天数、露地越冬指数和茎表皮耐冷生理生化指标等的杂种优势和细胞质效应分析.结果表明:①越冬耐冷性相关性状的相关分析表明,露地越冬指数与茎表皮电导率、丙二醛(MDA)含量、出苗至开花天数显著相关,出苗至开花天数这一生育期指标与电导率、茎粗极显著相关.(②二年生陆海杂种F1的耐冷性具备超亲优势,一年生陆海杂种F1的耐冷性只具有中亲优势而不具备超亲优势,同时二年生材料的耐冷性强于一年生,说明陆海杂种F1二年生栽培更有优势.③一二年生棉花耐冷性的细胞质效应均不显著,但存在一定的核质互作效应,且在不同的正反交陆海杂种F1组合中具有多样化特征.

关 键 词:棉花  多年生  耐冷性  杂种优势  细胞质效应

Abstract:The interspecific heterosis and cytoplasm effect in cryotolerance and its related traits of annual and biennial cotton were researched in order to provide theoretical basis for cross breeding.4 couples of reciprocal crosses,which were produced by 4 cotton materials with different grades of cryotolerance,were used to investigate the heterosis and cytoplasm effect in cryotolerance and its related traits(plant height,stem diameter,days from emergence to flowering,overwintering survivorship,physiological and bi...
Keywords:Cotton  Perennial  Cryotolerance  Heterosis  Cytoplasm effect
