2003 m. Nr. 2 Combining ability of morphological and anatomical traits in carrot (Daucus carota L. ssp. sativus (Hoffm.))
Topcross crossing of carrots was
carried out at the Lithuanian Institute of Horticulture in 1996 (O. Gaučienė).
Seven lines with cytoplasmatic male sterility (CMS) (N0557, N0563, Š0380b,
Š0494, G0639, G01982, G03003) and the testers Vitaminnaja 6, NIIOCH 336, and
No.01309 were used in the crosses. According to the ratio of general and
specific combining ability it is possible to presuppose that for inheritance of
the morphological and anatomical traits of carrot roots genes with additive
effects were of essential significance, though genes with dominant and
epistatic effects were significant as well. The length, weight and smooth
surface of roots of CMS lines to a greater scale are controlled by genes with
dominant and epistatic effects, though the impact of genes with additive
effects is also essential.
Genes with additive effects are important for inheritance of root diameter, while genes with dominant and epistatic effects are less significant. Genes with non-additive effects were more significant for inheritance of root phloem diameter than those with additive effects. Genes with additive effects controlled the heritability of root phloem color and root xylem diameter, though genes with non-additive effects were significant as well.
