通过分析唐抗５号的主要优点，确定目前京郊夏玉米新品种选育的育种目标应为：１．首要的是早熟性：夏播全生育期（播种－成熟）应在１００天以内，所需积温在２４００℃以下为宜，在早熟性选育方面应特别重视将前期出叶速度快、生长期短与后期灌浆强度大，脱水快两者相结合。２．稳产性强：在感病、一般肥水条件或不利的气候年份，仍能达到亩产４００ｋｇ左右的产量水平。３．高产潜力大：在一般地块应稳定在４００～５００ｋｇ，高水平地块应具有６００ｋｇ产量水平；４．对多种病害具综合抗性：应对大、小斑病、眼斑病、矮花叶病毒病、粗缩病、褐斑病、青枯病等多种病害具综合抗性；５．适应性好：对各种土壤肥力水平、不同的播期及气候年份均有较强的适应性；６．制种产量高：制种产量应在２５０ｋｇ／亩以上，并且制种技术简便、易操作。上述６项育种目标对今后京郊夏玉米引种示范也具参考意义
By analyzing the main advantages of Tangkang 5, the goal of breeding new summer maize cultivars in Beijing suburbs should be determined as follows: 1. The first is premature: Summer sowing the whole growth period (sowing - maturity) should be less than 100 days, the required accumulated temperature below 2400 ℃ is appropriate, in premature breeding should pay special attention to the early out of the leaf fast, growing season Short and late grouting strength, dehydration fast combination of the two. 2. Stability and strong: In susceptible, general fertilizer and water conditions or unfavorable climate year, still can achieve about 400kg per mu yield level. 3. High yield potential: in general block should be stable at 400 ~ 500kg, high-level block should have a production level of 600kg; Comprehensive resistance to a variety of diseases: to deal with large and small spot disease, eye spot disease, dwarf mosaic virus disease, curative disease, brown spot, bacterial wilt and other diseases with comprehensive resistance; Adaptability: a variety of soil fertility levels, different sowing dates and climate years have strong adaptability; 6. High seed production: seed production should be 250kg / mu or more, and seed production technology is simple and easy to operate. The above six breeding objectives for the future introduction of Beijing suburbs of summer corn is also a reference demonstration
