Variety yield and adaptation studies are of great importance in increasing cotton production and cultivation. This work was carry out to determine yield(seed cotton and fiber) and yield parameters (plant height, sympodial branches, boll number, seed cotton weight, 100 seed weight and ginning outturn) of 46 cotton genotypes, two of which belong to barbadense and forty-four of hirsutum species, under east Mediterranean ecological conditions of Kahramanmaras-Turkey in 2013 and 2014. According to the analysis of variance yield and yield parameters showed significant differences between genotypes. Year and genotype-year interactions were not significant for all characteristics studied. Based on two-year average results, cotton cultivars BA-119, ST-468 and Furkan gave higher seed cotton and fiber yield per hectare than the others. Minimum seed cotton and fiber yield was observed in Maydos. Cotton varieties BA-119, ST-468 and Furkan can be recommended to cotton producers for production regions due to their high seed cotton and fiber yield.

The aim of this study was to determine seed cotton yield, yield components and fiber technological properties of four mutant cotton varieties from Azerbaijan (Agdas-3, Agdas-6, Agdas-7 and Agdas-17) and three local standard varieties (Maras-92, Sayar-314 and Stoneville-453) belonging to Gossypium hirsutum L. The study was carried out at the experimental field of Koruklu Agricultural Research Station in Sanliurfa Province (Akcakale-Harran Plain) in the South-east Anatolian Region of Turkey. The trial was established in randomized block design with four replications in four years (2001 to 2004). In the study, plant height, monopodia, number of sympodia and boll, weight of seed cotton per boll, ginning outturn, 100 seed weight, seed cotton yield, earliness ratio, fiber length, fiber fineness, strength and uniformity were investigated. According to the results of four years' trials, the varieties, in all investigated characters except fiber fineness, strength and uniformity and year x variety interactions for plant height, number of bolls per plant, seed cotton yield and first harvest ratio, were found to be significant. The highest sympodial number was taken from Agdas-3 variety (13.79), the highest number of boll per plant was taken from Agdas-17 (15.41) and the highest seed cotton weight per boll was taken from Agdas-7 (5.54 g). All Agdas varieties had less ginning outturn than local standard varieties. The highest seed cotton yield was obtained from Agdas-17 (3654.2 kg ha -1 ), followed by Agdas-3 (3593.8 kg ha -1 ). All Agdas varieties had more seed cotton yield than standards except Agdas-7. Among Azerbaijan varieties, Agdas-3 was the earliest maturing variety with 81.3% of first harvest ratio. All investigated varieties were similar to each other in fiber technological properties. In conclusion, it can be said that among Azerbaijan varieties, Agdas-17 and Agdas-3 had higher seed cotton yield than local standard varieties, and they are the most hopeful varieties for Southeast Anatolian Region.
A field experiment was conducted during 2012–2013, and 2013–2014 with two dates of sowing as main plot and six genotypes as sub-plot treatments. Late sowing resulted in significant reduction in the days to 50 % flowering, days to 50 % boll bursting and days to maturity as well as number of GDDs for boll bursting and maturity compared to normal sowing. The fiber quality parameters, viz., 2.5 % span length, uniformity ratio, micronaire value, fiber strength, elongation and fiber maturity exhibited significant decline under late sowing. However, short fiber index increased under late sowing. Late sown crop could not develop a full canopy surface area as evidenced by reduced plant height, sympodia, leaf area and LAI at different growth stages. The Bt hybrid, Ankur-3028 BG-II recorded significantly higher plant height, sympodia, number of bolls, boll weight, seed cotton yield, seed and lint index and fiber properties like 2.5 % span length, fiber strength. The Bt hybrid G.Cot.Hy.-8 BG-II was early in terms of days to 50 % squaring, flowering, boll bursting and maturity and required less GDDs to attain a particular growth stage. The genotype Ankur-3028 BG-II took significantly higher number of GDDs during flowering to boll opening stage.
Association analysis among agronomic and fiber quality traits in color-cotton (Gossypium hirsutum)
Journal of Pharmacognosy and Phytochemistry, 2019
Improvement in the seed cotton yield with stable natural Color is an important goal in Color-cotton breeding. Seed cotton yield being a complex quantitative trait is affected by both genetic and environmental factors. Correlation studies pave a role in selection of yield influencing traits and gives an idea how traits are associated with it. We evaluated 240 Color-cotton genotypes with five white genotypes as checks during kharif 2016 at the Agricultural Research Station (ARS), Dharwad farm, University of Agricultural Sciences, Dharwad using an augmented design. Analysis of variance indicated that there was significant variation in the experimental material. Seed cotton yield had highly significant and positive correlation with its component traits viz., plant height, number of monopodia per plant, number of sympodia per plant, number of bolls per plant, ginning outturn and boll weight. These traits can be used as surrogate traits for improvement of yield. Fiber color was negatively associated with upper half mean length of fibre, fiber strength, uniformity index and elongation value. It thus seems that improvement of fiber quality traits and improving intensity of pigmentation simultaneously is challenging. Intensity of pigmentation was directly associated with fiber fineness and maturity ratio. Thus, improvement of fiber color retaining other fiber quality traits should be the priority breeding approach in Color-cotton.
Correlation Analysis of Yield and Fiber Traits in Upland Cotton ( Gossypium hirsutum L . )
2016
An experiment was carried out in a Randomized Complete Block Design with four replications and eight varieties viz. FH-114, CRIS-134, NIA Ufaq, Sohni, NIAB-777, Reshmi, Chandi and Shahbaz of upland cotton at experimental field of Nuclear Institute of Agriculture, Tandojam, during the year 2013, for assessing the correlation between yield and fiber traits in upland cotton genotypes. The observations were recorded on ginning outturn (%), staple length (mm) and micronaire value (μg/inch). Significantly maximum ginning outturn (39.27), staple length (30.37) and fiber fineness (3.95) was recorded by variety Reshmi. Correlation studies were analyzed for ginning outturn (%), staple length (mm), micronaire value (μg/inch). Results revealed that staple length was positive significantly associated with plant height, monopodial, ginning outturn which indicated that these qualitative characters can be used as reliable selection criteria to improve qualitative value of cotton.
Comparative Yield Performance of New Cultivars of Cotton (Gossypium Hirsutum L.)
A field experiment was conducted to asses the growth and yield performance of five cultivars of cotton i.e. FH-115, FH-207, FH-901, FH-113 and MNH-786, during spring 2006. Significant differences in plant height, number of sympodial branches per plant, number of bolls per plant, average boll weight, seed cotton yield, ginning out turn, fiber length and fiber fineness were recorded among the cultivars. The cultivar FH-115 statistically produced maximum yield due to more number of sympodial branches, number of bolls per plant and higher ginning out turn.
