Combining Ability Estimates for Tomato (Lycopersicon lycopersicum (L.) H. Karst) Resistance to Nematode (Meloidogyne spp.) in the Sudan Savannah of Nigeria

Nineteen entries consisting of seven parental lines plus twelve F1 hybrids derived from a line x tester mating design were evaluated under irrigation in a randomized complete block design (RCBD) with three replications in two locations (Gashu’a and Maiduguri) during the dry season of 2013/2014. Evaluations were done to estimates the combining ability variance, general combining ability (GCA) effect of parents and specific combining ability (SCA) effect of hybrids.
