2023
Namazova L.H.
The purpose of the current study was to estimate the crossing ability and chromosome pairing behavior of intergeneric F1 hybrids between Ae. ventricosa (DvDvNvNv) and Triticum aestivum (AABBDD) crosses. During the production of T. aestivum – Ae ventricosa hybrids, it was observed that F1 hybrids' morphological traits were intermediate between parents, the plants grew vigorously but were completely sterile. Seed set ranging from 2.17 to 8.00 %. Hybrids (2n = 5x = 35) produced without embryo rescue methods. The present study revealed that, the average frequency of chromosome associations at metaphase I was averaged 25.39 univalents and 4.78 bivalents. All received F1 hybrid plants were identical, they exhibited good tillering ability and manifested traits from both parents.
