For the quantitative characteristic of the associative treats complex there were chosen grain weight per ear as an essentional quantity and there were searched biological relationships with the 100 grain weight, no of grain/ear, tiller number and plant height. The searches were conducted on 36 hybrids of F1 which had been taken from triple test cross. There has been certified the highest physiological homeostatsis coefficient in the stocks SMH-57, SMH-75-1 and WOB-21. To estimate the breeding value was used ACA - associative combining ability. It has appeared that the most worthy stocks on account of ACA were WOB-21 and SMH-57. ACA can be used as a criterion in estimation of genotypes in the heterosis rye breeding
