Combining Ability for Stem Borer, Chilo partellus (Swinhoe) Resistance in Sorghum

  • S. P. Singh
  • A. N. Verma


Combining ability analysis for three stem borer resistance parameters, i.e. “dead hearts”, leaf injury and stem tunnelling, revealed that both additive and non-additive types of gene effects were involved in the inheritance of these attributes. The specific combining ability (sca)/general combining ability (gca) variance ratios further indicated predominance of additive gene effects for stem tunnelling and non-additive effects for “dead hearts” and leaf injury. The genotypes, IS 2123 and IS 5469 are good general combiners for all the three parameters. Among F1, hybrids, IS 1054 × IS 5469 and IS 18551 × IS 2123 expressed good sea for all the parameters of stem borer resistance. The use of IS 2123 and IS 5469 parental genotypes in the future breeding programmes is suggested.

Les analyses d’aptitude à la combinaison ont été effectuées pour trois paramètres de résistance au foreur des tiges, à savoir les coeurs morts, le dégât foliaire, les tiges évidées. Ces analyses ont mis en évidence le rôle tant des effets génétiques additifs que des effets génétiques non-additifs dans l’hérédité de ces attributs. Par ailleurs, les rapports d’aptitude spécifique à la combinaison (asc)/aptitude générale à la combinaison (age) ont indiqué la prédominance de l’action génétique additive pour les tiges évidées, alors que l’action génétique non-additive a été plus marquée dans le cas des coeurs morts et le dégât foliaire. Une bonne aptitude générale à la combinaison pour tous les trois paramètres a été constatée chez les deux génotypes IS 2123 et IS 5469. Au niveau des hybrides F,, les meilleures combinaisons pour la résistance au foreur des tiges sont IS 1054 × IS 5469 et IS 18551 × IS 2123. L’exploitation de ces génotypes ainsi que de leurs hybrides dans les futurs programmes de sélection est proposée.
