pedigree of eight Martonvasar varieties, to the greatest extent

(25 %) in Martonvasari 25 and Mv Magma. Bezostaya 4 can be

detected in the pedigrees of twenty-two Martonvasar varieties,

but with the exception of two varieties, Martonvasari 21 and

Mv Madrigal, its parental ratio is less than 10 %. This can be

explained by the fact that in the majority of cases the crosses

were not carried out with Bezostaya 4 itself, but with

Martonvasar lines created using this variety. Rannyaya 47 is

only present in the genealogy of one variety, Martonvasari 18.

Considering the mean contributions of the six Krasnodar

varieties it can thus be concluded that Bezostaya

made up

26.24 %of the total parental ratio of the Martonvasar varieties,

Kavkaz 18.01 %, Krasnodar 1 16.07 %, Avrora 15.31 %, Bezostaya

2 6.64 % and Bezostaya 4 2.51 %. All in all the six varieties

bred by Lukyanenko thus had a total parental ratio of 45.28 %

in the state registered Martonvasar varieties.

time Stupice belongs to share company SELGEN, which was

established in its present form in 1991 by its separation from

OSEVA. Winter and spring wheat and spring barley are

included in the present breeding programmes of Stupice

station. Since the year 1922 till these days

wheat and 9 varieties of spring wheat were registered. In the

year

varieties and 4 spring wheat varieties in Czech Republic. Some

of them are also registered abroad.

The cooperation with Krasnodar Lukyanenko Research

Institute of Agriculture was intensive mainly in years 1970-

1990. We were using many varieties and lines in our crossing

programmes. The most succesful parent was BEZOSTAJA 1,

which is in the pedigree of five our winter wheat varieties —
