Abstract:
The knowledge of morphological traits role to the tolerance increase
on some climatic unfavorable inductions could be constitute the main
objectives for creating of new potato genotypes.
The evaluation of the environmental inductions upon morphological
traits is motivated by obtaining of some information concerning the new
cultivars capacity in order to moderate some interrelations types less
favorable.
For emphasizing of some interrelations between above factors, in the
experiments structure six potato cultivars belonged to the early (Ostara and
Magic), semi early (Astral and Rapsodia) and semi later (Sante and
Desirée) categories were included.
The index foliar values of semi early and semi later cultivars were
bigger than realized on early cultivars.
Among the tested cultivars, the Astral, Rapsodia and Sante had a
maintaining duration of the foliar surfaces bigger than the other analyzed
genotypes.
The cultivar Rapsodia was influenced very little by yearly
characteristics of main climatic factors upon the maintaining duration of
maximum foliar surfaces at cultivar Rapsodia was observed
In majority of years (60%) the last stage on the tubers grows was
influenced by the unfavorable meteorological conditions.
