摘　　要：甜菜新品种中甜-工大321(原代号为轻工糖F 68)为标准偏高糖型杂交种,以四倍体FOT为母本,二倍体268中的三个系号(1:1:1)作父本,父母本按1:3比例杂交选育而成.在1999～2001年全国甜菜品种区域试验中,中甜-工大321其块根产量、含糖率、产糖量三年平均分别比对照提高-5.09%、1.76度、5.67%.2002年,在甜菜品种生产示范试验中,中甜-工大321其块根产量、含糖率、产糖量分别比对照提高-2.6%、1.63度、5.9%.该品种适应性好、抗病性强、块根品质优良且含糖高,适宜在新疆、内蒙古、山西、黑龙江等省区种植.Zhongtian-HIT 321 is the new polyploid hybrid of sugarrbeet, which belongs to NZ type.The variety was bred by crossing tetraploid FOT with three diploid lines of 268（1 ： 1 ： 1）. The ratio of hybriditation is 3 ： 1. The result of regional test from 1999 - 2001 showed that the average root yield and sugar content and sugar yield increased - 5.09%, 1.76°S,5.67 % than CK, respectively. The result of demonstrative trial in 2002 showed that the average root yield and sugar content and sugar yield were higher than CK- 2.6%, 1.63°S, 5.9%, respectively.The suitability of the variety is very good. It has resistance to Cercospora leaf spot and root rot. The quality of root is very good. It has high sugar content.This variety is suitable to be planted in Xinjiang, Inner Mengolin, Shanxi, and Heilongiiang province, etc.
