Abstract

GREBENNIKOVA, I. G., A. F. ALEYNIKOV and P. I. STEPOCHKIN, 2011. Diallel analysis of the number of spikelets per spike in spring triticale. Bulg. J. Agric. Sci., 17: 755-759

There was developed a computer program for calculating the combining ability of spring triticale varieties and for carrying out the genetic analysis of parental quantitative traits. The program was tested on hybrids experimentally obtained as a result of crossing between four spring triticale varieties according to a complete diallel scheme. There was selected a variety perspective for the trait “the number of spikelets per spike” breeding.

Key words: triticale, diallel analysis, combining ability, program, genetic parameters
