Inheritance of grain esterase genes in rye populations (Secale cereale L.)

Cytology and Genetics 2004, v 38, number 5, 16-23

Genetic analysis of four tow straw rye populations has been carried out basing on the trait electrophoretic spectrum of grain esterase isozymes. Expression of seven independent Est genes has been shown. Three of them are clustered and their intrapopulation polymorphism exceeds two allels. Comparative analysis of the frequences of different genes in parental populations and in F₂ with literature data about localization of Est genes makes it possible to carry out chromosomal localization of the genes identified according to the fact of presence or absence of linking with the genes of rye self-incompatibility.
