摘要: Received 30 September 2010Accepted 6 January 2011ABSTRACT - Incorporating wild germplasm such as S. pimpinellifolium is an alternative strategy to prolong tomato fruit shelf life(SL) without r educing fr uit quality . A set of ecombinant inbr ed lines with discr epant values SL and weight (FW) wer e derived byantagonistic-diver gent selection om interspecific cr oss. The general objective this esear ch was evaluate Genotype x Y ear(GY) Marker ear (MY) interaction in these new genetic materials for both traits. year principal effects GYinteraction were statistically significant SL. FW but GY wasnot. marker effect MY not significant.Though highly influenced by conditions, some genome regions appeared maintain a stable across years ofevaluation. Fruit weight, instead, more independent effect.Key words: amplified fragment length polymorphism; plant breeding; resources; Solanum section Lycopersicon;quantitative genetics.
