摘要:

【目的】研究新疆北疆苹果杂种后代抗寒性的遗传规律,筛选出抗寒性强的苹果新品种,为新疆苹果抗寒选育奠定基础。【方法】以苹果品种花红×元帅、国光×花红、冬立蒙×花红等3个组合的杂种一代(F1代),以及赤阳×新红(花红×元帅)、金冠×新光(国光×花红)、金冠×新冬(冬立蒙×花红) 等3个组合的杂种二代(F2)代为材料,分析苹果杂种F1代、F2代抗寒力性状和F1代与大苹果重交的后代抗寒力遗传倾向,以及抗寒小苹果与大苹果正反交杂种组合的抗寒力。【结果】抗寒力杂种苗统计,F1代为26.45%,而F2代仅1.35%,F2代较F1代降低了25.1%。F2代均比F1代变异率高。其中以金冠×新光(国光×花红)组合变异率最高。各级次出现株数顺序为4级>2级>3级>1级>0级。【结论】抗寒小苹果与不抗寒大苹果杂交,杂种后代在抗寒力受小苹果影响很大,小苹果有很强的遗传能力,以抗寒力强的F1代作亲本与大苹果杂交,F2代抗寒力显著降低;用不抗寒大苹果和抗寒小苹果互为父母本杂交时,以抗寒小苹果为母本显著优于其作父本者。

Abstract:

【Objective】This project aims to screen out new apple varieties with strong cold hardiness by studying the heredity disciplinarian of cold hardiness in apple hybrid progenies, so as to lay a foundation for the development of coldhardiness breeding of apples in North Xinjiang.【Methods】The F1 generations hybrid progeny of Huahong×uanshuai, Guoguang×Huahong, Donglimeng×Huahong, and the F2 generations hybrid progeny of Chiyang×Xinhong (Huahong×Yuanshuai), Jinguan×Xinguang (Guoguang×Huahong), Jinguan×Xindong (Donglimeng×Huahong), were used as test materials.The genetic tendency of cold hardiness in the first and second generations of apple hybrids, the offspring of recrossing between F1 generation and big apple, and the reciprocal hybrid combinations of small apple with cold resistance and big apple were investigated.【Results】F1 has a cold resistance of 26.45%,and F2 is only 1.35%,The F2 generation has decreased by 25.1% compared the F1 generation.F2 generation has a higher mutation rate than F1 generation,among them,the combination of Jinguan×Xinguang(Guoguang×Huahong)has the highest variation rate.The order of the number of plants appearing at each level is level 4>level 2>level 3>level 1>level 0.【Conclusion】After the small cold resistance apples were hybridized with excellent big apples, the cold hardiness of filial generation was affected greatly by small apples.Small apples had strong hereditary capacity.When F1 generation with strong cold hardiness was crossed with big apple, the cold resistance of F2 generation decreased significantly.When reciprocal cross between the big apples without cold hardiness and small apples with cold hardiness were carried out, the small apples with cold hardiness as female parents were significantly better than them as male parents.
