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…

Features of Chromosome Introgression from Gossypium barbadense L. into G. hirsutum L. during the Development of Alien Substitution Lines
TLDR
The analysis of morphobiological traits revealed that monosomic F1 hybrids were more similar to the donor line, while BC1F1 hybrids showed previously undetected traits, which may indicate hidden structural variability in these genomes that did not affect meiotic division.
The Utilization of Translocation Lines and Microsatellite Markers for the Identification of Unknown Cotton Monosomic Lines
TLDR
The primary objective of this chapter is to report the use of chromosome‐specific SSR markers and a well‐defined tester set of cotton translocation lines from the Cotton Cytogenetic Collection at Texas A&M AgriLife Research to confirm chromosome specificity of monosomic lines in Uzbekistan cytogenetic collection of cotton.
Karyotype and RAPD Diversity in Four Varieties of Gossypium hirsutum L.
TLDR
Each variety of Gossypium hirsutum could be characterized by diverse karyotypes and molecular data after fluorescence banding revealed genomic alteration and karyotype diversification within the four varieties.
Cotton Germplasm Collection of Uzbekistan
TLDR
A history of the collection development, maintenance, management and problems of ex situ conservation as well as utilization of germplasm resources are reviewed in this paper.
Cytomorphological investigations in colchicine-induced polyploids of Lablab purpureus (L.) Sweet
TLDR
Morphological and cytogenetical changes in the polyploidy of L. purpureus, as a result of colchicine treatment, could not be significantly inherited in nextgeneration and successful induction of stable tetraploids in next generation is a challenge for the researchers.
Differential Fluorescent Banding in 11 Varieties of Gossypium hirsutum L. from Bangladesh
Eleven varieties of Gossypium hirsutum L. (cotton) released by the Bangladesh Cotton Development Board, viz., CB-1 (Cotton Board-1), CB-2, CB-3, CB-4, CB-5, CB-6, CB-7, CB-8, CB-9, CB-10 and CB-11

Use of meiotic FISH for identification of a new monosome in Gossypium hirsutum L.
TLDR
Use of molecular cytogenetic methods to identify a new plant aneuploid in cotton exemplifies the fact that a physicochemical karyotypic chromosome identification system is not required a priori for application of new molecular cytogenic methods, thus indicating their potential applicability to nearly all plant species.
IDENTIFICATION OF MONOSOMES FOR SIX CHROMOSOMES IN GOSSYPIUM HIRSUTUM
TLDR
The cytological identification of monosomes for 6 of the 26 chromosomes of cotton, an amphidiploid species with withstanid deficiencies of whole or parts of chromosomes, has been reported.
The Development and a Cytogenetic Study of Monosomics of Gossypium Hirsutum L.
TLDR
Only 28 primary monosomics showed normal pairing at metaphase-1 of meiosis of cotton, and new morphological characters were detected among the monosome plants of cotton.
[Evaluation of the effect of pollen irradiation on karyotype variability in M2 cotton plants].
TLDR
The primary monosomics isolated in M2 were found to be cytologically more stable and more viable, since they had higher meiotic indices, pollen fertility, and seed formation.
Evaluation of the Effect of Pollen Irradiation on Karyotype Variability in M2 Cotton Plants
The karyotypes of biomorphologically abnormal cotton (Gossypium hirsutum L.) plants obtained in M2 after pollination with pollen irradiated at dose rates 10, 15, 20, and 25 Gy were studied. Various
Evaluation of the Effect of Pollen Irradiation on Karyotype Variability in M1 Cotton Plants
The effect of pollen irradiation at dose rates of 10, 15, 20, and 25 Gy on variability in cotton plants Gossypium hirsutum L. was studied. The modified plants showed a reduced fertility, mainly
Monosomics in Egyptian Henbane, Hyoscyamus muticus L.
TLDR
The meiotic behaviour and fertility of the six monosomic H. muticus plants with 2n-1=27 chromosomes isolated from populations raised from seeds treated with higher doses of gamma rays were studied.
Aneuploids induced by deficiencies of chromosome 9 and analysis of the time of nondisjunction in cotton
TLDR
Stained paraffin sections of ovules at different stages of development of monotelodisomic 9 and normal plants (TM1) were analyzed to determine the time and probable causes of nondisjunction during megasporogenesis.
Development of one set of chromosome-specific microsatellite-containing BACs and their physical mapping in Gossypium hirsutum L.
TLDR
Comparative analysis of physical marker positions in the chromosomes by BAC-FISH and genetic linkage maps demonstrated that most of the 26 BAC clones were localized close to or at the ends of their respective chromosomes, and indicated that the recombination active regions of cotton chromosomes are primarily located in the distal regions.
