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.
