AB  - The inheritance, gene effect and combining ability for produc-tive tillering in 4 divergent cultivars (Srbijanka, Partizanka, KG. 56 and PKB 111) were studied in diallel crosses (without reciprocals). Plants of the F2 generation were analysed. The results obtained showed that inheritance of productive tillering was different (partial dominance, dominance and over-dominance). Analysis of the genetic components of variance showed that dominance played a more important role in the inheritance of productive tillering than additive variance. The frequency of dominant alleles was higher than that of recessive ones. The degree of dominance was higher than one, which indicated over-dominance for all crossing combinations. Regression analysis indicated a dominant mode of inheritance (over-dominance). Parent cultivars showed the presence of genetic diversity in the arrangement of dominant and recessive genes for productive tillering. Analysis of variance for combining ability showed that non additive gene effects had a higher impact in the inheritance of productive tillering. Also, the GCA/SCA ratio was lower than one indicating a preponderance of non-additive gene action. The best general combiner was Partizanka cultivar, but the highest value of specific combining ability occurred in the Srbijanka x PKB 111 combination.
AB  - U dialelnom ukrštanju (bez recipročnog) četiri divergentne sorte pšenice (Srbijanka, Partizanka. KG-56 i PKB-111) proučavan je način nasleđivanja, efekti gena i kombinacione sposobnosti za produktivno bokorenje. Proučavanja su izvršena na biljkama F2 generacije. Na osnovu dobijenih rezultala može se zaključiti da je način nasleđivanja produktivnog bokorenja bio različit (parcijalna dominacija, dominacija i super dominacija) i zavisio je od kombinacije ukrštanja. Analiza komponenti genetičke varijanse ukazuje da su dominantni genetički efekti za nasleđivanje ovog svojstva značajniji u odnosu na aditivne. Frekvencija dominantnih alela je veća od frekvencije recesivnih. Prosečan stepen dominacije je veći od jedinice, što ukazuje da se radi o superdominaciji uzevši u obzir sve kombinacije ukrštanja. Regresiona analiza ukazuje na dominantni tip nasleđivanja (superdominacija) pri čemu su roditelji bili divergentni u pogledu rasporeda dominantnih i recesivnih alela. Analiza varijanse kombinacionih sposobnosti pokazuje veći udeo neaditivnih genetičkih efekata, pri čemu je odnos OKS/PKS manji od jedinice. Od ispitivanih sorti najbolji opšti kombinator za produktivno bokorenje je Partizanka. a najveću vrednost PKS imala je kombinacija Srbijanka x PKB-111.
