| Abstract: | The methods of quantitative genetic analysis were presented for estimating the chromosome effects and the gene effects of quantitative characters in common wheat-wheatgrass alien addition Unes. These methods are based on the cytogenetics of addition lines and the priciple of quantitative genetics. The chromosome effects and the gene effects of a Triticum aestivum-Elytrigia elongata (2n = 70) addition line 31505 were estimated. The main results were as follow: a) 6 quantitative characters in all characters investigated have relation to alien chromosomes. b) Chromosome effects showed dosage effects. Some chromosomes effects affected by the background of common wheat signficantly. c) Additive effects of alien chromosomes (d']) are the most important gene effects, and they showed similar in different crosses from the same character. d) There are certain interactions between alien chromosomes and common wheat chromosomes. |
