Abstract A natural yellow leaf mutant named 06883, found in tomato（Lycopersicon
esculentum Mill.）variety‘Zhongshu No.4’, can be inherited stably. Originally the leaves were green, but the first true leaf color turned into yellow during the period of four leave and one shoot. The fruits turned to red slowly, and became hard which is good for storage. The mutant was reciprocally crossed with tomato variety‘Zhongshu No.4’, and the genetic analysis indicated that the mutant is nucleolus inheritance and controlled by one recessive gene. It can be used as a phonotypical marker to identify purity of F1 hybrids.
We roughly mapped the mutant gene using SSR molecular markers. Three SSR markers LEaat006, LEtat002 and Tom196-197 were linked to the mutant gene. They were 8.9 cM, 16.3 cM and 18.7 cM apart from the mutant gene, respectively.
