通过2年试验，测定了优质油菜品种产量、经济性状、生育期、抗病性和品质等多项指标，综合评价、筛选出最好的双低油菜新品种KT0601、 20-5-26，适合在云南保山市大面积推广应用；20-5-14表现较好，下年可进行示范种植；KT0607、 KT0610可续试一年；KT0604各方面表现均较差，抗逆性较弱，可淘汰。

Studies on Rape Variety and Tests Screening

Comprehensive identificated a group of cabbage double-low rapeseed new varieties, in Yun Nan Province from 2007 to 2008, about its high-yield, stability, resistance and regional adaptability in different ecological conditions, which provided scientific basis for auditing and promoting the use of rape new vari- eties. The tests were completely random group. Repeated three times. The quarter net area was 13,5 m2,The basic miller was 150 000strain/hm2 .The test results tested the yield of the high-quality rape variety, its economical trait and growth stage .disease resistant and quality .and a number of indicators comprehensive evaluating and screening the best double-low new rape variety .KT0601 (It, s in the second place in senate varieties in 2007, The yield was 5187.8 kg/hm2 and it was 663 kg/hm2 than the control output , increasing by14.7%), 20-5-26 (It, s in the first place in senate varieties in 2007-2008, The yield was 5337.8kg/hm2 and it was 813kg/hm2 than the control output, increasing by 18.0%; The yield is 4862.3 kg/hm2 in 2008 , and it is 849.8 kg/hm2 than the control output, increasing by21.2% ), which are suitable for promoting the use in the large area of Bao shan city. Yun Nan; 20-5-14 performants better, it can be model cultivation next year; KT0607, KT0610 can be continued trial for a year; KT0604 performants worse in different ab- stracts, Its resistance is weaker and it can be out.
