New botanical variants ofTriticum sphaerococcum Perc. andTriticum spelta L. developed by hybridization of species from the genusAegilops L. withTriticum aestivum L

Abstract

As a result of the hybridization ofAegilops ovata auct. non L. with theTriticum aestivum L. cultivar Bezostaja 1, new biological variants ofT. sphaerococ-cumPerc. have been obtained. Besides the basic morphological and biological characters, they possess also some new useful features, such as better expressed winter hardiness, resistance to fungal diseases, and higher content of protein. New botanical varieties ofT. spelta L. are a result of hybridization betweenAe. crassaBoiss. ssp.vaviloviiZhuk. (2n = 42) and different cultivars ofT. aestivum. Some of them have useful biological and agricultural characters and are considered to be of interest to further utilization in plant breeding. Thus, on the basis of all these results, new suggestions about the origin of the genusTriticum are made. At the same time, the new biological variants of both of these species increase the possibilities of their practical utilization in wheat breeding.
