Inheritance of some morphological traits in hybridization of grapevine cultivars Drenak crveni and Afuz-ali

Abstract

The variability and mode of inheritance of young shoot tip, leaf, grape and berry morphological characteristics were investigated in F1 generation obtained by crossing of Drenak crveni and Afuz-ali. Based on seedlings description, considering investigated characteristics, grouping was done by applying O.I.V. method. The conclusions about inheritance of characteristics were obtained based on results of Hi2 test. The consider able variability was expressed in hybrid population. For properties of leaf characteristics (largeness, shape, dividity, and incisions), exception from typical monogenic ratio was determined. The monohybrid inheritance was determined in density of leaf hairs and downs. The monohybrid mode of inheritance was not confirmed in grape characteristics (largeness, compactness and stem length) and berry characteristics (largeness, shape and taste), while skin color is monogenic property.

Praćene su varijabilnost i način nasleđivanja morfoloških osobina vrha mladog lastara, lista, grozda i bobice u F1 generaciji nastaloj ukrštanjem sorti Drenak crveni i Afuz-ali. Na osnovu opisa sejanaca izvršeno njihovo grupisanje po posmatranim obeležjima primenom propisane metode O.I.V-a. Zaključci o načinu nasleđivanja posmatranih osobina doneti su na osnovu rezultata Hi2 testa. U hibridnom potomstvu ispoljena je znatna varijabilnost svih proučavanih osobina. Za osobine razvijenog lista (veličina, oblik, izdeljenost, forma ureza) utvrđeno je od stupanje od odnosa razdvajanja karakterističnog za monogensko nasleđivanje. Za osobine lista kao što su gustina dugih i kratkih malja utvrđeno je da se nasleđuju monogenski. Od osobina grozda i bobice monogenski način nasleđivanja nije potvrđen kod veličine grozda, zbijenosti bobica, dužine peteljke, veličine, oblika i ukusa bobica, dok se boja pokožice nasleđuje monogenski.
