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。
In order to explore the genetic law of ’Luzhou black jade’ grape fruit traits, from 2013 to 2014, the fruit traits (including nuclear, fruit color, scent, Texture, soluble solids content, fruit weight and fruit shape) were analyzed. The results showed that 77.3% of the progeny mesocarp aborted lines and only 1 scented lines were present. The fruit color, texture, soluble solids content, fruit weight and fruit shape index of the progeny of hybrids showed a number of genetic traits Separation; fruit performance of non-nuclear, dark fruit color, crisp meat, small round, and other traits have genetic predisposition; soluble solids content more complex genetic. The study shows that ’Huashan black jade’ grapes can pass non-nuclear, dark-colored, crisp and round fruit shape to F1 generation with strong flavor, but it is hard to have fragrant strains; Trend, but there is the potential to choose a large fruit type strain.
