[Effect of genetic diversity in Hordeum vulgare L. and Secale cereale L. on their crossability and the development and viability of hybrid embryos and plants].

Abstract excerpt

A study was made of the effect of genetic diversity in cultivated barley and rye on seed setting, embryonic development, and viability of barley x rye hybrids grown in vitro and planted. The variation in seed-setting frequency was shown to be determined mainly by vegetation conditions and random factors, while the variation in proportion of seeds with embryos among the total seed set was determined by the genetic...
