摘  要：
甜研301是在改进多倍体育种技术的基础上育成的甜菜多倍体新品种。抗褐斑病、根腐病,含糖较高,稳产,优于当地推广品种及引进的国外多倍体良种。由于采用重点选择四倍体亲本、早代定向培育、多点鉴定和南繁北育等手段,优良性状迅速稳定。种植面积已遍布黑龙江中、北部、吉林西部、辽宁、内蒙东部及北京延庆等地,至1987年已累计推广90余万亩。

摘  要：
Tian Yan 301 is a polyploid sugar beet variety which was developed by using improved polyploid breeding technique. It resists to leaf spot (Cercospora beticola Sacc) and root rot (Fusarium oxysporum Schl) with high sugar and good stability in yield. In production demonstration, its root yield increased by 18.7%, sugar percentage-0.9% and sugar yieild——25.6% Disease resistance to leaf spot and root rot is superior to local va: rieties by 0.4-1 grade and 10-20%,respectively.Con(?)paring the Tian Yan 391 with someforeign polyploid sugar beet varieties, it increased sugar 1.7-3.0%, disease resistance 1-2 grade and 10-20%. Due to mainly selection in tetraploid parent, directive breeding in early generation, multi-site tests and south-reproduction and north-selection, the superior character stabilized rapidly.Since 1982, the total planting areas has been increasing. In 1987, it was about 60000 ha and spreaded widely in Heilonjiang, west of Jiling, east of Inner Mongolian and Yang ching region etc.
