NASLEÐIVANJE NEKIH MORFOLOŠKIH OSOBINA PRI HIBRIDIZACIJI<br />

Praæene su varijabilnost i naèin nasleðivanja morfoloških osobina vrha mladog lastara,<br />
lista, grozda i bobice u F1 generaciji nastaloj ukrštanjem sorti Drenak crveni i Afuz-ali.<br />
Na osnovu opisa sejanaca izvršeno njihovo grupisanje po posmatranim obelejima<br />
primenom propisane metode O.I.V-a. Zakljuèci o naèinu nasleðivanja posmatranih<br />
osobina doneti su na osnovu rezultata x 2 testa. U hibridnom potomstvu ispoljena je<br />
znatna varijabilnost svih prouèavanih osobina. Za osobine vrha mladog lastara (intenzitet<br />
obojenosti vrha antocijanima, gustina dugih malja i kratkih dlaèica), kao i za osobine<br />
razvijenog lista (velièina, oblik, izdeljenost, oblik zubaca, forma ureza) utvrðeno je<br />
odstupanje od odnosa razdvajanja karakteristiènog za monogensko nasleðivanje. Za<br />
osobine lista kao što su gustina dugih malja i kratkih dlaèica utvrðeno je da se nasleðuju<br />
monogenski. Od osobina grozda i bobice monogenski naèin nasleðivanja nije potvrðen<br />
kod velièine grozda, zbijenosti bobica, duine peteljke, velièine i ujednaèenosti velièine<br />
bobica, oblika i ukusa, dok se boja pokoice nasleðuje monogenski.<br />
INHERITANCE OF SOME MORPHOLOGICAL CHARACTERISTICS IN<br />
HYBRIDIZATION OF GRAPEVINE CULTIVARS DRENAK CRVENI AND<br />
AFUZ-ALI<br />
The variability and mode of inheritance of young shoot tip, leaf, grape and berry morphological<br />
characteristics were investigated in F1 generation obtained by crossing of Drenak<br />
crveni and Afuz-ali. Based on seedlings description, considering investigated characteristics,<br />
grouping was done by applying O.I.V. method. The conclusions about inheritance<br />
of characteristics were obtained based on results of x 2 test. The considerable variability<br />
was expressed in hybrid population. For properties of young shoot tip (intensity of<br />
anthocyanins, hairiness), and leaf characteristics (largeness, shape, dividity, shape of<br />
tooth and incisions), exception from typical monogenic ratio was determined. The<br />
monohybrid inheritance was determined in density of leaf hairs and downs. The<br />
monohybrid mode of inheritance was not confirmed in grape characteristics (largeness,<br />
compactness and stem length) and berry characteristics (largeness, shape and taste),<br />
while skin color is monogenic propertie.
