油菜不同引进品种在呼伦贝尔地区的适应性评价

Adaptability evaluation of different introduced canola varieties in Hulun Buir Region

【目的】筛选适宜在呼伦贝尔地区种植的优良油菜品种。【方法】以呼伦贝尔地区主栽品种青杂5号为对照,对引进的8个油菜品种(烁沣油067、烁沣油66、烁沣油963、陇油10号、冠油杂705、冠油杂815、利油杂710、利油杂819)生育期、农艺性状、产量、抗逆性和籽粒品质进行测定,综合评价不同品种在呼伦贝尔地区的适应性。【结果】8个引进的油菜品种在呼伦贝尔地区生长发育均表现良好,抗倒性、耐旱性、抗寒性、抗霜霉病、抗病毒病方面均较强。冠油杂705生育期为102 d,植株长势整齐,抗逆性强,芥酸和硫苷含量低;产量最高,为4049.0 kg/hm^(2),较对照品种增产11.6%;含油量为45.8%,较对照品种高2.3%。【结论】冠油杂705品种综合性状表现突出,可作为主要油菜品种在呼伦贝尔地区推广。

【Objective】In order to screen the excellent canola varieties suitable for planting in Hulun Buir Region.【Methods】Qingza No.5,the main cultivar in Hulun Buir Region,was used as the control,and the growth period,agronomic characteristics,yield,stress resistance and grain quality of 8 introduced canola varieties(Shuofengyou 067,Shuofengyou 66,Shuofengyou 963,Longyou No.10,Guanyouza 705,Guanyouza 815,Liyouza 710 and Liyouza 819)were determined.The adaptability of different varieties in Hulun Buir Region was comprehensively evaluated.【Results】The growth and development of eight introduced canola varieties were generally performing well in Hulun Buir Region.And they were better in lodging resistance,drought resistance,cold resistance,downy mildew resistance and virus resistance.Guanyouza 705 had a growth period of 102 days,with growing in order,strong stress resistance,low erucic acid and glucosinolate contents;the highest yield was 4049.0 kg/hm^(2),which was 11.6% higher than that of the control;the oil content was 45.8%,which was 2.3% higher than that of the control.【Conclusion】Guanyouza 705 had outstanding comprehensive characteristics,and could popularized as a main canola variety in Hulun Buir Region.
