For the difference between the domestic tomato, Solanum esculentum, and its wild South American relative, Solanum chmielewskii, the environmental variance accounts for 13 percent of the total phenotypic variance of fruit weight, for 9 percent of the total variance of soluble-solid content, and for 11 percent of the total variance in acidity. What are the broad-sense heritabilities of these traits?

Respuesta :

A sexually compatible wild tomato species known as Lycopersicon parviflorum has mostly gone unused in tomato breeding. In an interspecific cross between the wild species L.

Parviflorum and the elite processing tomato Lycopersicon esculentum E6203, the Advanced Backcross QTL (AB-QTL) technique was employed to search this genome for QTLs controlling traits of agronomic value (LA2133). 133 genetic markers were used to genotype a total of 170 BC2 plants (131 RFLPs; one PCR-based marker, I-2, and one morphological marker, u, uniform ripening).

In duplicated field trials conducted in California, Spain, and Israel, about 170 BC3 families were cultivated. They were then graded on 30 horticultural features. A total of 199 significant putative QTLs, ranging from 1 to 19 QTLs discovered for each characteristic, were found for all the traits. Despite the overall inferior phenotype of the wild species, at least one QTL was found for which the L. parviflorum allele was associated with an agronomically favorable effect for 19 (70%) traits (excluding traits for which effects of either direction are not necessarily favourable or unfavourable).
