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.
