Research on some characters in black currant progenies

Populations derived from selfs and crosses of a small number of black currant varieties with the variety Consort were analysed for various characters, viz. vigour, number of flowers, flowering time, ripening time, fruit-set, strig-length and berry size. Flowering began in the third growing year. In the next year the bushes could be assessed to best advantage. The results of the evaluations are:

   The vigour of the selfed progenies showed, with the exception of Consort, a clear inbreeding depression as compared with the hybrid populations.
