Integration of Conservation Strategies of Plant Genetic ... - Genres

genetical variances for six genetic systems must be genetical reserves.
Self-pollinated plants have neither inter-varietal variance, nor dominant variance (dD 2 ), nor overdominant
variance (dOD 2 ), nor variance of heterozygous epistasis. Homozygous epistasis variance is present, but
it is included in parent-offspring co-variance, being the part of additive variance (dA 2 ), because for wheat,
barley and other self-pollinated crops dg 2 = da 2 and rg = rA. Theoretical back
ground for creating a core collection of self-pollinated crops is quite clear now, and quick methods of
identifying each of the six genetic polygenic systems seem a good way for organization in situ and ex
situ conservation of plant genetic resources.
