“…Combined results showed that in M 1 , M 2 , and M 3 generations, there were 39 (60.9%) monosomic plants. These results do not correspond with the data of Galen and Endrizzi [7] who observed more monosomic plants in lower doses (4 Gy) in comparison with higher doses (12 Gy). …”

The use of aneuploid lines significantly increases the effectiveness of molecular-genetic analysis and the development of superior quality breeding lines via substitutions by alien chromosomes. To date, however, a complete set of aneuploid series for each cotton chromosome is not available. Here, we present the development of a monosomic stock collection of cotton (Gossypium hirsutum L.) from Uzbekistan, including the origin of 92 primary monosomics, meiotic metaphase-I analysis, study of tetrads of microspores, pollen fertility, and monosomic transmission rates for some monosomic lines. We report desynaptic effects of some monosomes detected both in parental and daughter monosomics, a positive role of interchanges in translocation heterozygous monosomics due to selective advantages of gametes with deficiency and a simultaneous interchange, pollen fertility variation, and strong differences in transmission rates. This monosomic cotton collection, developed using single genome background, will be useful for future breeding, genetic, cytogenetic, and molecular-genetic investigations of the cotton genome.

“…Хромосомная инженерия и отдаленная гибридизация К ультивируемый хлопчатник Gossypium hirsutum L. (2n = 52) является аллотетраплоидом и включает два субгенома (A t и D t ), поэтому он толерантен к потере отдельных хромосом или их плечей. На протяжении длительного времени в США проводились исследова-ния по выявлению моносомиков хлопчатника среди сортовых, гибридных и облученных популяций, а также среди цитогенетических линий End rizzi, Brown, 1964;Galen, Endrizzi, 1968;Endrizzi, Ram say, 1979). До 1985 г. были выделены и идентифициро-ваны моносомики по 15 из 26 негомологичных хромосом G. hirsutum.…”

“…During long-term investigations a big number of monosomic plants of different origin were isolated in the USA [5][6][7][8][9]. The majority of monosomes were found for chromosomes 2, 4 and 6 of the A-genome [10].…”
