Abstract

Three oriental and one semi-oriental variety and their diallel F1, F2 and BC hybrids were investigated for the variation of the number of leaves per stalk in generations obtained by back-cross hybridization. The trial was set up during 1997. The design was randomized block with four replications at the Experimental field of Tobacco Institute-Prilep. Counting was made in the period of buttonization of tobacco, and data obtained were processed by variational-statistical analysis. By diallel crosses, a maximum number of combinations in back-cross generations can be obtained. The investigations of BC-progeny enable us to estimate the effect of parental genotypes, which will improve this character in the newly created back-cross hybrids. The best results in increasing the number of leaves in the progeny were obtained by backcross hybridization with the Yaka variety YV 125/3. This variety showed the highest GCA for the character investigated. The highest SCA was obtained in the hybrid (P 12-2/1 x YV 125/3) x YV 125/3.
