Název v původním jazyce

Utilization of doubled-haploid technology in the breeding programmes of winter oilseed rape, flax/linseed, caraway, pea, poppy and hemp in Agritec Ltd.

Popis výsledku v původním jazyce

In Agritec, the doubled-haploid technology has been studied more than twenty five years in industrial crops (flax/linseed, winter oilseed rape, hemp), legumes (pea) and spicy/medicinal crops (caraway, poppy). The state-of-art of the technology enabled its use in the practical breeding and doubled-haploids of promising lines contributed to speed-up the breeding process and release new winter oilseed rape (microspore culture) and linseed (anther culture) varieties. Intensive research effort is carried out in other crops with various success. The most promising results have been recently obtained in caraway. Despite of flow-cytometric analysis, we were able to distinguish caraway DH-plants of anther origin from diploid plants from somatic tissues with the use of esterase isozymes. The effort to obtain haploid/doubled haploid regenerants resulted in haploid/mixoploid callus formation (pea, hemp) or in regenerants of somatic tissue origin (poppy). For further progress, we are recently using a new generation of synthetic cytokinin/auxin derivatives. The utilization of doubled-haploids – more than fifty years after this phenomenon discovery – may be considered as an integral part of modern plant breeding.
