Abstract
A quantitative genetic analysis was conducted to determine the inheritance of androgenetic response in hexaploid triticale One highly-responsive genotype (Do 1 triticale) and three low-responding advanced CIMMYT lines (Rhino, Juanillo 97 and Ira Drira) were used as parents to produce a complete set of reciprocal F1, F2 and backcross generations Estimates for genetic effects were determined using a generation-mean analysis following the method of Mather and Jinks Both embryo induction and plant regeneration potential fitted well with the simple three-parameter additive-dominance (AD) model indicating the absence of any significant epistatic effects Highly significant additive effects were detected for embryo induction, suggesting that breeding and selection can be effective in improving the induction response of triticale The high [d]/[h] ratio indicates dominance of the alleles causing high embryo induction The production of regenerant plants from embryos appeared to be a more complex trait because of its high sensitivity to environmental factors
