优质高产油菜新品系区域试验研究

Study on Regional Test of New Rapeseed Cultivar with High Quality

[目的]为安徽省优质油菜新品种的审定和推广种植提供依据。[方法]以皖油14为CK,研究了08-崇1、08-崇8、08-崇10、08-崇12、08-崇14-2、08-崇15-2、08-崇20-2油菜新组合在安徽巢湖、合肥、六安地区的适应性、产量及经济性状。[结果]08-崇15-2的产量最高,达3 501.2 kg/hm^2,比CK增产16.83%,其次为08-崇14-2,比CK增产11.14%;08-崇15-2、08-崇14-2的经济性状较好,有效角果数和每角粒数多,籽粒大。08-崇20-2组合熟期最早,比CK提前2.67 d。08-崇14-2的抗倒性强。[结论]综合评价,08-崇15-2、08-崇14-2抗性强,经济性状协调,适应性和丰产性好,可进一步参加省区域试验。

[Objective]The study aimed to provide the basis for examination and approval and promote planter of new variety rape in Anhui Province.[Method]With Wanyou 14 as CK,the adaptability,yield and economic characters of 08-chong1,08-chong8,08-chong10,08- chong12,08-chong14-2,08-chong15-2,08-chong20-2 in Chaohu,Hefei,Liuan of Anhui Province were studied.[Result]08-chong15-2 had the highest yield,which reached 3 501.2 kg/hm^2,secondly for 08-chong14-2,which increased 11.14%in comparison with CK.08-chong14- 2,08-chong15-2 had better economic characters,it had more effective pod number,seeds per silique and most grains.08-chong20-2 had earliest maturation,which advanced 2.67 d in comparison with CK.08-chong14-2 had stronger lodging resistance.[Conclusion]By comprehensive evaluation,08-chong15-2,08-chong14-2 had strong resistance,good economical characters,compatibility and yielding ability,thus can be applied for the trial planting in the whole province.
