Abstract

Abstract: The elite lines of L11，L19，L46 and L51 containing Tm-2a，I-2，Mi-1 and Cf-9 resistant genes were obtained in tomato with the aid of the molecular marker assisted selection. Seedling inoculation of these inbred lines confirmed higher disease resistant levels. The results of field trials also showed that the four selected disease resistance lines have better agricultural characteristics and may be used for tomato disease resistance breeding program in the future.

Key words: tomato, marker-assisted selection, disease resistance, pyramiding breeding
