RESEARCH ON YIELD STABILITY AND ITS QUALITY INDICATORS FOR WHEAT DIFFERENTIATED TECHNOLOGY MANAGEMENT IN LUVOSOIL SIMNIC CONDITIONS

For three years, 2009-2011 period, 25 wheat cultivars with different proveniencewas evaluated for yield, protein content, gluten content and gluten index, in conventional and ecological systems. On data base we made top list, where the equal value was assigned the same number of corresponding points taken place. The most mentioned cultivars in the positive way were: Şimnic 50, Capo, Josef, Trivale, Şimnic 30, Gruia, Izvor, Dropia and Delabrad, they were considerate the most stable for Simnic luvosoil. For yield stability, in any culture system was put in evidence the cultivars: Trivale, Gruia, Ciprian and Litera. For protein stability, in the top of list were the Romanian cultivars: Şimnic 50, Delabrad, Dropia şi Dor. Şimnic 50 presented gluten index values about 35 at all technology applied. It is recommended the best quality cultivar in all experiment
