    摘要:

    为了探索‘火州黑玉’葡萄果实性状遗传规律,2013~2014年,对‘火州黑玉’为母本的3个组合198个杂交后代的果实性状(包括核性、果色、香味、质地、可溶性固形物含量、果粒重和果粒形状)进行了分析研究。结果表明:后代中胚败育型株系占77.3%,有香味株系仅1个;杂交后代的果色、质地、可溶性固形物含量、果粒重、果形指数呈现数量遗传性状且连续广泛分离;果粒表现无核、深果色、脆肉、小粒、圆形等性状具有遗传倾向;可溶性固形物含量遗传较复杂。研究认为,‘火州黑玉’葡萄能将无核、深果色、脆质地、圆果形等性状以很强优势传递给F1代,但很难出现有香味株系;果粒呈变小趋势,但存在有选择大果型株系的潜力。

    Abstract:

    In order to explore the inheritance of fruit traits of ‘Huozhouheiyu’,we evaluated the fruit traits of 198 crossed progenies from 3 cross combinations with ‘Huozhouheiyu’ as female parent in 2013 and 2014,They were seed trait,feel color,fragrance,texture,soluble sugar content,fruit weight,and fruit shape.The results showed that 77.3% of them were embryo abortion types,only 1 was fragrance;The fruit color,texture,soluble sugar content,fruit weight,and fruit shape index showed quantitative genetic character and continuous widely segregation.The offspring fruits showed seedless,dark fruit color,crisp,small and circular genetic predisposition;The genetic of the soluble sugar content showed complex;and the narrow sense heritability of the fruit weight,fruit shape index,and soluble sugar content were low.The results indicated that ‘Huozhouheiyu’ could pass the traits to F1 generation with very strong heterosis,they were seedless,dark fruit color,crisp texture,and round fruit shape,but it was difficult to obtain the fragrance progenies.Although the fruit has become smaller,there was a trend of larger type.
