By Muhammad Naveed Arshad on Feb 6, 2019

WCRC WCRC2 Breeding

ABSTRACT The author suggests some modifications to the additive main effect and multiplicative interaction (AMMI) method to increase its accuracy for measuring stability of genotypes. Using the suggested modifications, four stability levels could be defined, high, above average, average and below average. The genotype with a high level of stabilit...

Concept of Graphical Genotypes for Analysing Introgressed Cotton Populations
By Muhammad Naveed Arshad on Feb 6, 2019

WCRC WCRC2 Breeding

ABSTRACT Cotton breeders have utilized genes from Gossypium barbadense to enhance fiber properties of Acala cotton G. hirsutum. This has been achieved only after many decades of careful selection and breeding. Extensive problems with interspecific hybrid population have frustrated breeders and prevented targeted introgression of genes for importan...

Evaluation of genetic diversity in short duration cotton (Gossypium hirsutum L.)
By Quanyi LIU on Jan 12, 2019

Agro-physio-Asia Breeding-Asia Breeding JCR

[Background] Cotton (Gossypium hirsutum L.) is an important fiber crop in Bangladesh. Genetic diversity among the genotypes of a germplasm has a great importance for cotton breeding. An experiment was carried out at the experimental field of Cotton Research, Training and Seed Multiplication Farm, Sreepur, Gazipur during the cropping season of 2015–...

Irrigation’s effect and applied selection on the fiber quality of Ethyl MethaneSulfonate (EMS) treated upland cotton (Gossypium hirsutum L.)
By Quanyi LIU on Dec 26, 2018

Breeding & Genetic improvement Agro-Physio-north-america JCR

[Background] Producing rainfed cotton (Gossypium hirsutum L.) with high fiber quality has been challenging in the Texas High Plains because of extended periods of insufficient rainfall during sensitive boll developmental stages. Genetic variation created by Ethyl MethaneSulfonate (EMS) mutagen has successfully improved fiber quality of cotton. Howe...

Selection Efficiency for Cotton Fiber Quality in Segregating Material by Different Instruments
By Muhammad Naveed Arshad on Dec 24, 2018

WCRC WCRC2 Breeding

ABSTRACT A breeding programme to develop varieties with a wide range of quality parameters to meet various end uses, requires rapid and accurate fiber quality assessment. This paper examines the potential of instruments to provide data for the selection of fiber quality parameters. Segregating genetic material (F2) from five intra-specific crosses...

Changes in Breeding Strategy for Needs in a Liberalized Cotton Industry
By Muhammad Naveed Arshad on Dec 24, 2018

WCRC WCRC2 Breeding

ABSTRACT Commercial cotton (G. hirsutum L.) production has been based on BPA and SATU varieties, grown in two ecological zones. Both have had a strong world market, the stronger, longer and finer fiber BPA finding a different market niche. The collapse of the seed replacement system developed by the Department of Agriculture and liberalization of...

Chromosomal Location of RFLP Markers Linked to QTL in Cotton
By Muhammad Naveed Arshad on Dec 24, 2018

WCRC WCRC2 Breeding

ABSTRACT Plant breeders are primarily involved in improving complex quantitative traits (QTL) that are controlled by many genes. Molecular markers linked to QTL will help breeders to monitor the hereditary materials associated with the QTL. Recently, our research unit reported a linkage map of a class of molecular markers called Restriction Fragme...

Combining Ability for Fiber Properties in Influential Upland Cotton Varieties
By Muhammad Naveed Arshad on Dec 24, 2018

WCRC WCRC2 Breeding

ABSTRACT A great number of germplasm lines have been used as parents in cotton improvement. Those contributing a larger proportion of genes to modern cotton cultivars than other germplasm are called influential lines. Based on the pedigree analysis of 260 cotton cultivars released in the United States between 1970-1990, the most influential cotton...

Reaction of some Segregating Populations and Newly Introduced Cotton
By Muhammad Naveed Arshad on Dec 24, 2018

WCRC WCRC2 Breeding

ABSTRACT Resistance of cotton cultivars in the Sudan to Xanthomonas campestris pv. malvacearum conferred by B2 B6 gene combination is no longer effective after the appearance of new races of the pathogen. Thus, new sources of resistance or new gene combinations are needed to protect the crop. This study was carried out to identify such a new sourc...

ABSTRACT A cotton improvement programme based on participatory plant breeding methods employed for food crops has been implemented in Benin for ht e last two years. It aims at reinforcing the relationship between farmers and research, regionalising cotton breeding thanks to active collaboration with grower associations. Hopefully, farmers will als...

Achieving Multiple Pest Tolerance Through Manipulation of Morphological Features in Cotton
By Muhammad Naveed Arshad on Dec 24, 2018

WCRC WCRC2 Breeding

ABSTRACT Breeding for tolerance to sucking pests and bollworm in cotton is treated as mutually exclusive events. Selection for resistance to sucking pests with more hairy leaves brought increased susceptibility to bollworms. An effort was made to select genotypes with high density hair on the lower leaf surface and low density hair on the upper su...
