NASLEÐIVANJE OSOBINA RAZVIJENOG LISTA<br />
U POTOMSTVU VINOVE LOZE DOBIJENOM UKRŠTANJEM SORTI<br />
MUSKAT HAMBURG I VILLARD BLANC<br />
D. Nikoliæ<br />
Poljoprivredni fakultet, Beograd-Zemun<br />
Od 21 morfološke osobine koje za opis i determinaciju sorti vinove loze preporuèuje<br />
Internacionalni institut za biljne genetièke resurse šest su osobine razvijenog lista. To su:<br />
velièina, broj renjeva, oblik zubaca, oblik peteljkinog sinusa, gustina poleglih malja i<br />
gustina uspravnih malja izmeðu nerava na nalièju razvijenog lista. Varijabilnost i naèin<br />
nasleðivanja navedenih osobina ispitivani su kod 90 sejanaca F1 generacije iz<br />
kombinacije ukrštanja Muskat hamburg x Villard blanc. Kategorizacija prouèavanih<br />
osobina izvršena je pomoæu sistema šifri OIV, a odreðivanje naèina njihovog<br />
nasleðivanja pomoæu 2 testa. Dobijeni rezultati pokazuju da je u hibridnom potomstvu<br />
ispoljena znatna varijabilnost svih prouèavanih osobina. Velièina razvijenog lista, broj<br />
renjeva razvijenog lista, oblik zubaca razvijenog lista i oblik peteljkinog sinusa<br />
razvijenog lista najverovatnije su uslovljeni veæim brojem genetièkih faktora, jer je pri<br />
prouèavanju naèina njihovog nasleðivanja ustanovljeno odstupanje od testiranih,<br />
monogenskih odnosa razdvajanja. Za gustinu poleglih malja i gustinu uspravnih malja<br />
izmeðu nerava na nalièju razvijenog lista utvrðeno je monogensko nasleðivanje.<br />
INHERITANCE OF MATURE LEAF PROPERTIES IN GRAPEVINE<br />
PROGENY OBTAINED BY CROSSING MUSCAT HAMBURG AND VILLARD<br />
BLANC CULTIVARS<br />
Of the 21 morphological property recommended by the International Plant Genetic Resources<br />
Institute for description and determination of grapevine cultivars six properties<br />
are those of the mature leaf, e.g. size, number of lobes, shape of teeth, shape of petiole sinus,<br />
density of prostrate and erect hairs between the veins on lower side. Variability and<br />
inheritance mode of these properties were analyzed in 90 seedlings of the F1 generation<br />
from the crossing combination of Muscat Hamburg x Villard Blanc. The properties analyzed<br />
were classified according to the OIV system of classification and 2 test was used<br />
to determine the inheritance mode. A substantial variability of the analyzed characteristics<br />
was recorded in the hybrid progeny. Mature leaf size, number of mature leaf lobes,<br />
shape of mature leaf teeth and shape of mature leaf petiole sinus were most probably affected<br />
by a great number of genetic factors because there were divergences with regard to<br />
inheritance in relation to the tested monogenic relationships of separation. Monogenic inheritance<br />
was determined with regard to the density of prostrate and erect hairs between<br />
the veins on lower side of the mature leaf.
