国家玉米品种试验中对照品种更迭与发展

对照品种的选择和更换应以通过审定、生产中表现较好的品种为依据,随着育种水平的发展适时更迭。品种推广走势与对照更换的时期一致,进一步说明对照品种的示范和标杆作用。玉米品种区试应适时提高对照水平,加大品种选择压力,针对性设置对照,提高区域品种竞争力,及早筛选后备对照品种。品种试验中对照品种或形式可以探索参试组合的平均或几个对照的综合考量,使品种试验更加科学,以此选拔出来的品种可信度和适应性更强,更能体现客观、公正、公平。

Change and Development of Check in Maize Varieties Plot Trial at State-level

Selection of check in maize varieties regional trial were based on approved and production well, and change accompanied by breeding level. Varieties popularization trend were coincide with check change time, which embodied the check model, should take active measures, such as selected better check at the appropriate time, increased the variety of selection pressure, and targeted to set the check, screened backup check cultivar. Concerned about the pilot plant density, variety or form of the check cultivar trials to explore the tested combination of average or a comprehensive consideration of several checks, so that more scientific check varieties, thus chosen from the variety reliability and adaptability would be stronger, more conducive to objectivity, impartiality and fairness.
