ASSESSING NEW FOREIGN VARIETIES OF FESTUCA ARUNDINACEA IN HAY MEADOW MANAGEMENT REGIME PUBLISHEDMihaela CORCHES, Luminiţa COJOCARIU, Cristian RUJAN
The yield of cultivars varies largely from their genetic productive potential, in relation to the environmental conditions and to their adaptability or tolerance to the main limiting factors (diseases, pests, unfavourable climatic conditions, genetic vulnerability. (Savatti, 2004). This paper aims at finding the productive potential of three foreign varieties of Festuca arundinacea, under Banat Plain conditions. In order to reach this goal, we studied three varieties of Festuca arundinacea in the experimental cycle 2008-2010 from the point of view of their dry matter y From the analysis of the synthesis of dry matter yields obtained in hay meadow management regime , by varieties of Festuca arundinacea , studied under the conditions in Timişoara, we notice that the best yields were recorded by variety Arid III (116.43 q.ha -1 ), being followed by Durango (average yield 2008-2010 of 108.37 q.ha -1 ) and variety Eminent (average yield 2008-2010, of 100.13 q.ha -1 ). Because the dry matter yields obtained by the three varieties of Festuca arundinacea are close, the yield differences are not ensured statistically. All three varieties of Festuca arundinacea obtained in the third year, 2010, their best yields, presenting great genetic homeostasis, which gives them the chance to adapt easily to the climatic conditions in Timişoara.ield in hay meadow management regime. The results show that all three varieties of Festuca arundinacea under study display high genetic homeostasis, which allows them to adapt very quickly to the climatic conditions in Timişoara, giving very good dry matter yields.
