The breeding between Gossypium hirsutum L. and Gossypium
barbadense L. purpose to increase yield and enhance fiber quality. The
cross populations between four hirsutum varieties, Darmi, Helius, LT 4 and LT
64 and barbadense variety, Avesto, were used as material. Interspecific F1
and F2 populations were evaluated in terms of heterosis, useful
heterosis and F2 depression for yield, quality parameters and
physiological characteristics such as stomatal density and parenchyma thickness
in cross section of leaf. All observed characters resulted negative heterotic
effects except fiber length and strength. Inbreeding depression for seed cotton
yield was highly negative in all hybrid combinations. The differences among
genotypes for stomatal density and parenchyma thickness were found to be
significant. The significant correlations showed that an increase in stomatal
density resulted in an increasing of fiber length and strength, whereas in a
decreasing of ginning out turn and fiber fineness. It should be concluded that stomatal
density can be used as selection criteria in early generations of interspecific
cotton breeding.
