W hite head cabbage has a broad fie ld o f application as vegetable.

Homozygous lines are used to develop heterosis hybrids F1. The two-year

regeneration time and self-incompatibility make this process very long (8-12

years).

In vitro

technique such as anther culture is more effective to induce

haploid plant formation and follow ing doubled haploid plants.

We have used anther culture in production o f haploid regenerants from

cabbage. Local Belarus cultivars and hybrids F1 were used. The donor plants

were grown to flowering in a grown room under a 16-h photoperiod at 12°-

14°C. Anthers were surface-sterilized with a sodium hypochlorite fo r 10 min,

washed tw ice w ith distilled water. In anther culture anthers containing

m icrospores in the late uninucleate stages were placed on a solid (0,6%

agar) MS medium containing 6% sucrose, 2 mg/l BAP and 0,8 mg/l NAA.

The basic medium was supplemented w ith serine and meso-inositol. The

anthers were cultivated at 7 days at 35°C before being transferred to 25°C.

Haploid (about 10%) and diploid plants were obtained.
