摘要
“吉甜201”系利用不同世代的自交系杂交,再进行单株自交分离,至生态型基本一致,再采取田间轮回选择与室内检测分析相结合、春夏播相结合等系统选择方法育出的标准偏高糖型品种。吉甜201比当地主要推广品种范育一号块根产量提高8.5％,含糖提高1.17度,产糖量提高17.5％。
The Jitian 201 was a NZ variety breed by systematic selection methods of crossing with inbreeding lines in different generations and individual plant selfing segregation until basic unanimity of ecotypes, then combining the recur-rent-selectioa in field with test and analysis in the laboratory, spring sowing and summer seeding etc.The root yield increased 8.5% and sugar content 1.17%,sugar yield 17.5% than the local commercial variety-Fanyu 1.
