✦ Synopsis

For an accelerated and simplified selection of desirable characters in linseed or flax breeding programmes application of various biotechniques would be useful, e. g. ( 1) somatic cell culture from meristems or calluses for rapid propagation of plants and in vitro-selection, (2) antheror microspore-culture for regeneration of haploid plants, (3) interspecific hybridization of cultivated species and their wild relatives, e. g. by embryo rescue, (4) culture and regeneration of hybrid protoplasts (asexual hybrids), ( 5 ) genetic engineering with isolated protoplasts ("direct gene transfer") and ( 6) application of genetic engineeringvia specific vector systems (cf. Fig. 1). Some of these cell and tissue culture methods and techniques have already been applied in practical linseed breeding programmes. Fat Sci. Technol. 91.
