The Influence of Wheat Genotypical Diversity and Growing Conditions on the Fertility of the First Backcross Progeny Triticum durum Desf. x
The author studies the fertility of the first backcross progeny T. durum x T. timopheevii under conditions of different vegetations. It was stated that the environmental conditions have a stronger effect on the F1BC1 plants seed fertility then genotypical diversity of parental forms. Growing hybrids under the most favourable conditions reduces the number of sterile plants and increases seed fertility to 30 percentage.
Key words: durum wheat, timopheevii wheat, hybrids, fertility, sterility, backcross, environmental conditions, genotypical diversity.
