Abstract

Information
about heritability and combining ability for neps and seed coat neps is
necessary for breeding strategies. Seven cotton cultivars including 4 lines and
3 testers were mated in line x tester mating design. The 19 genotypes were
grown in RCBD with three replications at Aydın-Turkey conditions in 2014.
Non-additive gene action was important in the expression of SCN size, neps
count and neps size. The parental lines Carmen and Claudia were good combiners
for most neps characteristics.  Carmen x
Flash, Julia x ST-468, Claudia x Carisma and Gloria x Flash were superior crosses
for selection in further generations. It was
recommended that the selection of individual plants for neppiness should be
performed in later generations (F₄-F₆).
