THE CYTOLOGY AND PHYLOGENETICS OF THE DIPLOID SPECIES OF GOSSYPIUM

American Journal of Botany, 1966
Meiotic chromosome behavior of 11 inter‐genomic hybrids of Gossypium (2n = 26) were investigated. Per cell univalent frequencies at meiotic metaphase I in these hybrids were: A genome × Cgenome—G. herbaceum × sturtianum, 10.53; G. herbaceum × australe, 18.05. A genome × E genome—G. smnalense × arboreum, 21.82. B genome × C genome—G.

A comparison of chemical properties of seeds of Gossypium species

Economic Botany, 1960
The possibility of utilizing gene pools from wild cottons in the improvement of commercial varieties, with special reference to seed quality, has led to the quanititative analysis of seeds from several species of Gossypiumun. The prinmary purpose of the study was to suipply data for Gossypiumt species that may serve to aid.

Seed esterases, leucine aminopeptidases and catalases of species of the genus Gossypium

Theoretical and Applied Genetics, 1972
Polyacrylamide and starch gel electrophoresis were used to analyze the isozyme makeup of three enzyme systems (esterases, leucine aminopeptidases and catalases) from the dormant seeds of twenty-nine species within the genus Gossypium.Isozyme variation was observed for all three enzymes between the species of the different genome groups.

Meiosis of a Triple Species Hybrid in Gossypium

Nature, 1944
SKOVSTED1,2 brought forward considerable cytological evidence that New World (n = 26) cottons originated by amphidiploidy from crosses between ancestral Asiatic (n = 13) and American (n = 13) parents. Recently Harland3 and Beasley4 have independently synthesized by colchicine treatment amphidiploids from hybrids between present-day Asiatic and American

FLORAL PIGMENTATION STUDIES IN THE GENUS GOSSYPIUM II CHEMOTAXONOMIC ANALYSIS OF DIPLOID GOSSYPIUM SPECIES

American Journal of Botany, 1965
The chromatographic pigment arrays of nine diploid species ( G. arboreum, G. anomalum, G. herbaceum, G. stocksii, G. sturtii, G. thurberi, G. gossypioides, G. raimondii and G. klotzschianum ) were studied. Among the Old World cottons,

Hybridization of Gossypium species through in ovulo embryo culture

Plant Cell, Tissue and Organ Culture, 1986
An interspecific hybrid of the sexually incompatible species G. hirsutum cv. Laxmi and G. arboreum cv. Jyoti was obtained through in ovulo embryo culture. Eightto twelve-day-old ovules were excised and cultured on Beasley and Ting's medium supplemented with Indol-3 acetic acid (5×10-6 to 7×10-6 M), Kinetin (5×10-6 to 5×10-8 M), Gibberellic acid (5×10-7

Effect of sowing date on yield of cotton species) (Gossypium

Indian Journal of Agronomy, 2001
Recently the farmers of western Uttar tween sowing dates and varieties for seed- Pradesh are inclined to switch over to cotton yield. Pooled data revealed that maxi- summer cotton (Gossypium sp.), which mum yield was recorded i n . ~ b1 sown on might escape adverse effects of rainy season.

Genome-wide analysis of the MADS-box gene family in polyploid cotton (Gossypium hirsutum) and in its diploid parental species (Gossypium arboreum and Gossypium raimondii)

Plant Physiology and Biochemistry, 2018
The MADS-box gene family encodes transcription factors that share a highly conserved domain known to bind to DNA. Members of this family control various processes of development in plants, from root formation to fruit ripening. In this work, a survey of diploid (Gossypium raimondii and Gossypium arboreum) and tetraploid (Gossypium hirsutum) cotton ...

Feeding by seed bugs and weevils enhances germination of wild Gossypium species

Oecologia, 1992
Seeds of Gossypium sturtianum and G. thurberi do not readily germinate under most conditions. Increased germination of G. sturtianum was associated in nature with the presence of a seed bug, Oxycarenus luctuosus. Experimental and descriptive studies were conducted in Australia and Arizona to test the hypothesis that more seeds of G.

The Native Species of Gossypium (Malvaceae) in Africa, Arabia and Pakistan

Kew Bulletin, 1987
Because of their immense importance to man, the cultivated species of Gossypium have been extensively studied over the years and divided into a multitude of varieties, forms and races. It is not my intention to deal with the cultivated part of the genus although four species G. arboreum L., G. barbadense L., G. herbaceum L. and G. hirsutum L.
