BEHAVIOR OF SOME ROMANIAN TRITICALE VARIETIES IN THE CLIMATIC CONDITIONS OF THE CENTER OF MOLDAVIA, ROMANIA / Comportarea unor soiuri romaneşti de triticale în condiţiile pedoclimatice din centrul Moldovei, Romania.

Abstract

Knowledge of the particularities of the new varieties response to environmental conditions is important for the best possible territorial zoning and site stating that they need to occupy in varieties structure for each area. This paper presents research results of environmental testing of six Romanian triticale varieties at the Agricultural Research-Development Station (A.R.D.S.) Secuieni, Neamţ county, Romania, during 2007-2012 and followed the zoning of the most adapted and performing genotypes, increasing their biodiversity, so as to diminish the genetic and environmental vulnerability of agroecosystems. On average for the five years of experimentation, triticale yields achieved ranged from 6984 kg/ha (Cascador) and 8439 kg/ha (Haiduc). Of the five years of experimentation, the crop years 2008-2009 and 2010-2011 were normal in terms of rainfall, the yields achieved in these years being the highest. Depending on the average yield achieved in the five years of experimenting, the top three varieties were ranked Haiduc (8439 kg/ha), Stil (8320 kg/ha) and Plai (7961 kg/ha), the first two varieties having a very low coefficient of variability (<10). During the experiment, Romanian triticale varieties showed good resistance to winter, lodging and diseases.
