Abstract: Estimation of response to marker-assisted selection (MAS) is critical to breeding programs. To investigate MAS for line development, two cucumber recombinant inbred lines (RILs) (7026B76 and 7022C8) differing in plant habit were mated, and F4 and F5 progeny were MAS selected to improve both yield and quality. The broad-sense heritability (h2B) ranged from 0.22 to 0.45 for yield (fruits per plant), and from 0.09 to 0.20 for fruit length:diamter ratio (L:D). Selection was effective in maintaining phenotypic performance in F4 progeny, but not after advanced generation (F5) progeny selection (i.e., yield decreased, but fruit quality was maintained). The lack of response may be due to low trait heritability.
