the confidence interval was: FL - 7.4%, L-10.8%. The correlation

coeficients between F

and derived F5f F

generations were

positive with values for different groups: FL-r=0.154 to 0.815” ,

L-r = 0.170-0.724*. Selection advance was for FL method

between 18.3-47.6% and heritability 0.41-0.71 depending on

the collection concerned. The required level of frost resistance

in Czech Republic is lower than in Russia. (Hanisova. Horcicka.

Hanis, 2000).

Doubled haploids by in vitro androgenesis have been

produced in cooperation with Academy of Sciences and Research

Institute of Plant Production in Prague-Ruzyne since 1992 in

Fp F

and F

generations. Our results has shown that performance

the DH lines are not so good as lines produced by conventional

systems. Till this days we have not positive results.

We expect in near future the introduction of molecular

technics in our breeding programme, mainly molecular markers

for quality and disease resistance.
