ЦИС-эффект гомозиготного генетического фона на частоту кроссинговера у кукурузы
The cys-effect of homozygous background on crossing over in maize. From the inbred maize lines MK01 and Ku123, the isogenic lines containing mutant markers lg1, gl2, c1, sh1, wx1 were obtained. They differ from original forms by pair of mutant markers. The hybrids of isogenic lines with the original forms are heterozygous only within marked region and are almost homozygous in the rest of the genome. Homozygous background leads to increase of mean recombination rate from 5.4% to 10.1% in c1-sh1, from 15.0% to 35.6% in s1-wx1 and from 18.2% to 32.8% in lg1-gl2.
