摘要
从国内外引进105个苹果品种，在四川典型的湿热、少日照生态区的雅安进行试验研究，结果表明：中熟品种首红、超红、艳红、新红星、好矮生具有较强的适应性。抗病性强，其中超红、首红抗病性最强，其褐斑病病情指数仅分别为2．37、3．40；短技型性状明显，新红星的节间长度为1．87cm，超红为1．90cm，艳红为1．97cm，均显著短于对照（红冠）的2．93cm，新红星、艳红短果枝结果习性强，分别占结果枝总数的96．5％、93．3％，宜密植栽培；早果性好，丰产性强，品质优良，如艳红固酸比过17．1，赵红达16．8，首红达13．3。现正在雅安、绵阳、德阳、江油、广元等地示范推广。
105 apple varieties were introduced and studied, the results s how that mid-season varieties, e·g 'Redchief', 'Supreme' Red','Ultra Red', 'Starkrimson', 'Well Spur', are adaptive and disease-resistanti. 'Supreme Red' and 'RedChief' are the top two in disease resistallce (the disease index for brown spot is 2.37 and 3.40,respectively);The specific property of dwarf shoof is very good, the internode length of 'Starkrimson', 'Supreme Red' and 'Ul'tra Red'is 1. 87cm, 1.90cm and 1.97cm, respectiyely, signifcantly shorter than CK'S (Richard Delicious) 2.93 cm; The main fruiting branches of 'Starkrimson' and 'Ultra Red' are spurs(the percentage being 96.5% and 93.3%, respectively), these apple variet ies are suitable high-density planting, they are early bearing variet ies with high productivity and fruit quality, the Total Soluble solids to Acid Ratio of 'Ultra Red','Supreme Red' and 'RedChief' is 17.1, 16.8 and 13.3, respectively.The extension of these good apple varieties is being carried on in Yaan city, Mianyang city, Deyang city, Suining city, Jiangyou city and Guangyuan city.
