Abstract

In 1993 and 1994, general and specific combining abilities for the characters number of leaves per stalk and dry tobacco yield per stalk in varieties P 12-2/1, YV 125/3, FO and their first generation hybrids were investigated. According to the results, the following statements might be drawn: - Analysis if variance for the general (GCA) and specific (SCA) combining abilities for the number of leaves per stalk revealed the GCA and SCA are highly significant, with GCA variance being prevailing. This means that the character number of leaves per stalk is mainly related to the effect of additive genes and the ratio GCA/SCA is 7,02. - The values for GCA indicated that the best variety for number of leaves per stalk is YV 125/3. Good results for this character were also obtained in the variety P 12-2/1, whereas the results for variety FO were not good. - The analysis of SCA revealed that hybrid P 12-2/1 x YV 125/3 achieved the highest value, with 1% significance. - Analysys of variance for the character dry tobacco tield per stalk showed that it is related to the effect of additive and non-additive genes, with additive gene effect being prevalent. The GCA/SCA ratio is 7,33. - Best results for the character dry tobacco yield per stalk were obtained in the variety FO, and the worst in P 12-2/1. - In relation to the character dry tobacco yield per stalk, hybrids that would be interesting for further investigation are YV 125/3 x FO and P 12-2/1 x FO.
