油菜品种筛选试验研究

通过2007～2008年两年试验,对云南省新育成的一批甘蓝型双低油菜新品种,进行不同生态条件下的丰产性、稳产性、抗逆(病)性及区域适应性的综合鉴定,为油菜新品种审定、推广利用提供科学依据。试验采取完全随机区组排列,3次重复,小区净面积13.5m2,基本苗15.0万株/hm2,试验结果,测定了优质油菜品种产量、经济性状、生育期、抗逆(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(2007年产量居参试品种第2位,产量5187.8kg/hm2,较对照增产663kg/hm2,增幅14.7%)、20-5-26(2年均居参试品种首位,2007年度产量5337.8kg/hm2,较对照增产813kg/hm2,增幅18.0%;2008年度产量4862.3kg/hm2,较对照增产849.8kg/hm2,增幅21.2%),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1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.
