2010-2020年我国育成甘蔗新品种的亲本分析

Parent Analysis of New Sugarcane Varieties Developed in China from 2010 to 2020

以我国2010—2020年通过的省级以上审(鉴、认)定或农业农村部登记的97个甘蔗杂交选育出的新品种为调查对象,研究分析了不同甘蔗作杂交亲本选育效果。结果表明:在调查育成的97个甘蔗新品种中,‘粤糖’系列、‘新台糖’系列和国外引进材料作亲本选育品种分别为62个、58个和40个,分别占比31.63%、29.59%和20.41%,说明‘粤糖’系列、‘新台糖’系列和国外引进材料作亲本对我国甘蔗品种选育效果显著。育成的97个品种共使用79个亲本,‘新台糖22号’和‘新台糖25号’作亲本育成品种分别达18个和13个,分别占比9.18%和6.63%。使用了9个含本土‘割手密’血缘的‘崖城’系列作亲本育成品种达19个,占比9.69%,说明在甘蔗野生种本土‘割手密’的开发利用和扩大遗传基础方面取得显著的成效。

The parents of 97 sugarcane cultivars developed in China(provincial or national registration from 2010 to 2020 were analyzed to explore the breeding effect of different sugarcane parental clones.The results showed that:among the 97 developed cultivars,62,58 and 40 were Yuetang series,"ROC”series and foreign introduced ones,accounting for 31.63%,29.59%and 20.41%,respectively.It indicated that Yuetang series,"ROC"series and for⁃eign introduced clones as parents have significant effects on sugarcane breeding in China.Among the 97 developed varieties,79 parents were used,of which 18 and 13 varieties were developed by"ROC"22 and"ROC"25 as parental clones,accounting for 9.18%and 6.63%,respectively.19 varieties were developed from 9 Yacheng series containing Spontaneum blood,accounting for 9.69%of the total.Suggested that remarkable results have been achieved in the development,utilization and expansion of genetic basis of sugarcane wild species Spontaneum.
