Resumo: A new "Galpão Comum" tobacco variety carrying resistance to the Tobacco Mosaic Virus - TMV, was developed through the backcross metbod. The initial crosses employed the most commercial CO-D (Palotina) variety and the donor parente Ky- 14 and Ky-12 that are Burley varieties and also belong to the air cured group. These donor parents possess the hypersensitivity (HS) type of resistance to TMV. The resultant TMV immune variety, named CSC 300, was higher in yield and had more desirable cured leaves, according to the amount of tanish leaves (L) and quality grade 2 produced. The phenotypic characteristics of this new variety were considered quite similar to the recurrent parent (CO-D/Palotina). The smoking panels tests were very good and had a strong agreement with the normal characteristics for the "Galpão Comum" favorite type. This new variety was developed to be given to the formers, for the 1986/87 crop season, by the Genetic and Breeding Research Center of Souza Cruz.

A nova cultivar, imune ao TMV, foi obtida pelo método do retrocruzamento, utilizando-se, inicialmente, as cultivares CO-D (Palotina) como pai recorrente, e duas cultivares de fumo Burley (Ky-14 e Ky- 12) como doadoras dos genes "NN", responsáveis pelo caráter imunidade (hipersensibilidado das células infectadas). A nova cultivar foi superior à comercial tanto em produtividade quanto em qualidade das folhas curadas, possuindo características fenotípicas bastante somelhantes à cultivar CO-D. Os testes envolvendo painéis de fumaça foram muito bons alcançando grande concordância com os padrões organolépticos esperados dentro do tipo de fumo "Galpão Comum". Esta nova cultivar foi entregue aos produtores de fumo para plantio já na safra-87, através do "Centro de Pesquisas e Melhoramento Genético do Fumo" da Souza CruzPesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPontes, Oscar F.
