The regional as well as the international crop production is expected to be influenced by climate change. This study describes an assessment of simulated potential cotton yield using CropSyst, a cropping systems simulation model, in Northern Greece. CropSyst was used under the General Circulation Model CGCM3.1/T63 of the climate change scenario SRES B1 for time periods of climate change 2020-2050 and 2070-2100 for two planting dates. Additionally, an appraisal of the relationship between climate variables, potential evapotranspiration and cotton yield was done based on regression models. Multiple linear regression models based on climate variables and potential evapotranspiration could be used as a simple tool for the prediction of crop yield changes in response to climate change in the future. The CropSyst simulation under SRES B1, resulted in an increase by 6% for the period 2020-2050 and a decrease by about 15% in cotton yield for 2070-2100. For the earlier planting date a higher increase and a slighter reduction was observed in cotton yield for 2020-2050 and 2070-2100, respectively. The results indicate that alteration of crop management practices, such as changing the planting date could be used as potential adaptation measures to address the impacts of climate change on cotton production.

High Yielding Varieties

Thirty six candidate cotton varieties developed by different breeders of Pakistan were tested consecutively for two years (2017 and 2018) and at seven locations of Sindh and Balochista Provinces in national coordinated varietal trials (NCVT).  The trials were conducted to explore seed cotton yield potential and fiber properties against two check varieties (CIM-602 and FH-142/IUB-13).  As per claim of the breeders, the samples of all varieties for both the years were sent to four designated biotechnological laboratories for conducting biochemical tests also. The results revealed highly significant differences among the varieties for both the years. During the year 2017, on an average of six location, top ten high yielding varieties recorded were GH-Haadi, Weal-AG-6, VH-189, GH-Mubarak, Weal-AG-5, MNH-1026, Badar-1(DG), FH-444, CIM-343 and TJ-Max(DG) which yielded 3434, 3407, 3342, 3255, 3251, 3248, 3185, 3154, 3134 and 3131 kg/ha seed cotton yield respectively. When the results of 2018 trial were looked at, averagely top ten high yielding varieties were GH-Haadi, ICI-2121, CRIS-613, VH-383, VH-189, NIAB-898, FH-490, Cyto-225, Tahafuz-10(DG) and GS-Ali-7 with 3526, 3356, 3306, 3139, 3101, 3091, 3084, 3074, 3060 and 3026 kg/ha of seed cotton yield respectively. However, on an average of both the years (2017 and 2018), top ten high yielding varieties were GH-Haadi, VH-189, CRIS-613, Weal-AG-6, GH-Mubarak, Badar-1(DG), ICI-2121, Weal-AG-5, FH-940 and MNH-1026 producing 3480, 3221, 3186, 3155, 3113, 3083, 3057, 3054, 3042 and 3042 kg/ha of seed cotton respectively. As regards fiber properties, (04 candidate varieties) could qualified all fiber standards set by government. The biochemical test results received from all four laboratories revealed that on an average of four laboratories and two years, the trait purity range recorded was from 42 to 96 percent, whereas, quantification of Bt toxin ranged from 0.74 to 2.62. From the present study, it was concluded that almost 15-20 candidate varieties have the potential to be included among already approved varieties for commercial cultivation in the province of the Punjab.

A field experiment was conducted at ICI Research Farm, Multan to evaluate the effect of different sowing dates on plant height, number of monopodia, number of sympodia, number of bolls per plant, boll weight, seed cotton yield kg/ha of two upland cotton varieties (ICI-2121 and ICI-2424) developed by ICI Pakistan Limited, Multan against a standard check variety IUB-2013 during 2019, and 2020 years.  These varieties were planted on 1st April, 15th April, 1st May, 15th May, 1st June, and 15th June, at ICI Cotton Research Station, 19-Kasi Vehari Road, Multan.  Results revealed that statistically highly significant differences in planting dates were observed for all the parameters studied except number of monopodial branches and boll weight which depicted non-significant differences. Regarding varieties and interaction between varieties and planting times, similar trend of statistical differences was observed. As regards to planting dates, generally, all the parameters under study showed their maximum performance when crop was planted on 1st May followed by 1st April planting date, whereas, minimum performance of the parameters was recorded when the crop was planted on 15th June followed by 1st June. Regarding varietal performance, on an average, maximum plant height (146cm) was observed in ICI-2121 followed by IUB-2013. Same trend of performance of varieties regarding number of monopodia and sympodia per plant was observed.  Regarding average number of bolls per plant in different varieties, it was observed that ICI-2121 produced maximum (32 bolls) followed by ICI-2424 (31 bolls) and IUB-2013 (28 bolls) irrespective of planting dates. The same trend of varietal performance regarding boll weight was recorded. When seed cotton yield (kg/ha) was evaluated, on an average of varieties, ICI-2121 produced maximum seed cotton yield (1228 kg/ha) followed by ICI-2424 and IUB-2013 which produced 1147 and 1046 kg/ha seed cotton yield respectively irrespective of planting dates. It was concluded that under agro-climatic conditions of Multan, 1st May planting date was evaluated as optimum cotton sowing time. Before or after 1st May, this study does not recommend growing cotton in this particular zone.  Among cotton varieties, ICI-2121 is recommended for sowing under this planting time being producing higher yields.

SUMMARYWork was conducted in Alexandria and Sakha districts, Egypt, to study the influence of planting dates and seeding rates on yield of seed cotton, yield components and fibre properties of Egyptian cotton, Menoufi variety, during 1970–1972. Four planting dates were studied, together with four seeding rates. The number of lost plants decreased as planting date was delayed, and the highest yield of seed cotton resulted from the third date of planting (20–23 March) using hand-drilling. Neither planting dates nor seeding rates had significant effects on most of the other characteristics studied.

Abstract. Cotton breeding in Bulgaria is mainly aimed at improving the earliness, productivity and fiber quality of modern varieties. The creation of new genetic diversity is one of the basic prerequisites for the success of breeding programs. The aim of the study was to evaluate cotton lines obtained by intraspecific and remote hybridization combined with backcross technology, with a view to their most effective usage in selection. Twenty-three lines were included in competitive variety trials conducted during the 2014-2017 period. The averaged results showed that lines 550, 639, 641, obtained by remote hybridization, appeared to be very promising. These three lines were distinguished by the best combination of productivity, fiber length and fiber lint percentage, and by these three indicators they exceeded the standard variety Chirpan-539. A new cotton variety Aida (No. 457) was approved, which in seed cotton yield and fiber yield, and technological fiber properties surpassed the standard varieties Chirpan-539 for earliness and productivity and Avangard-264 for fiber quality. The candidate variety 535 continued the state variety testing. Two new candidate cotton varieties No. 550 and No. 553 were released. In the state variety testing the three candidate varieties confirmed their qualities. The obtained lines, distinguished by one trait or by a complex of qualities, enriched the gene pool of Bulgarian cotton.
