Anther culture response in heterozygous triticale (× Triticosecale Wittmack) populations

The subject of research was the anther culture response of 186 lines of winter crop triticale coming from two types of crossings: A×B and (A×B)×C. The number of embryoids and green regenerants obtained from particular lines were adopted as property indicators. The examined lines were characterised by a relatively good ability to create either single embryoids or conglomerated embryoids, but the number of green regenerants obtained later on from such structures was generally low. It was found that there were no significant differences between these objects both with regard to the ability to create embryoids and green regenerants in the case of anthers collected from hybrids from simple crossings, whilst there were significant differences (with p=0.05) in the case of hybrids originated from crossings of the type (A×B)×C. The coefficients of heritability of the ability to create embryoids was h 2 =0,682 for anthers coming from hybrids of the type: A×B and h 2 =0,371 for anthers collected from hybrids of the (A×B)×C type. However genetic conditioning of the ability to regenerate green plants was 0.699 and 0.522 respectively. It may thus be supposed that the ability to create embryoids passed onto the next generation would be better with the forms originating from crossing of the A×B type, and the heritability of the ability to create green plants would be similar with both types of hybrids.For both of the groups compared, also the coefficients of variability CV(p) and CV(g) were calculated as well as the coefficients of correlation between the number of embryoids and the number of green regenerants obtained from them at a later phase
