DTOPSIS法综合评价新疆日光温室番茄新品种的初步研究

[目的]利用DTOPSIS法对新疆日光温室番茄作出更合理的分析评价,同时也为了番茄新品种在不同地区的推广提供参考.[方法]以番茄新引品种2007～2008年调查数据为资料,利用DTOPSIS法进行综合分析评价,初步研究了该方法在番茄新品种评价应用中的相关问题.[结果]DTOPSIS法比只用产量进行分析更为合理,能将各品种的性状指标归纳为统一的量化综合指标,并能反映各品种的稳定程度;在10个参试品种中,FA1420、FA189、FA1903 的Ci值相对较高,综合性状良好,与实际表现一致.[结论]利用DTOPSIS法评价新疆日光温室番茄新品种,可以较全面的分析出新品种的适应性,有效提高新品种推广的成功率.

A Preliminary Evaluation of New Tomato Varieties in Solar Greenhouse of Xinjiang with DTOPSIS Method

【Objective】The aim of the study was to evaluate the new tomato varieties bred in the solar greenhouse with DTOPSIS method and popularize the new tomato varieties.The comprehensive evaluation of the new tomato varieties were introduced with the investigation data obtained in 2007-2008.The paper also discuessed the existing problems relating to the comprehensive evaluation of newly introduced tomato varieties.【Result】The results indicated that the DTOPSIS method was superior to that of the yield analysis in variety which could conclud the trait indexes of all the varieties in the comprehensive indexes of the unified quantization;and it showed the genetic stability of the varieties.Of 10 varieties tested,FA1420,FA189 and FA1903 had the grested Ci values corresponding well with the actual performance.【Conclusion】Utilzation of the method of mathematical DTOPSIS to evaluate the new breed tomato in solar Greenhouse of Xinjiang,can analyze the adaptability of new varieties ,can improve rate of spreading the new varieties effectively.
