Comparison of The Fiber Characteristics of the Some Cotton Varieties Ginned by Using Sawgin and Rollergin

In this study carried out in 2015 under conditions of Kahramanmaraş province of Turkey, it was aimed at determining the effects of sawgin and rollergin methods on fiber quality in some cotton (Gossypium hirsutum L.) cultivars. In the study varieties of Lydia, Carisma, PG 2018, Flash, BA 440, BA 119 Maraş-92 and Erşan-92 were used as experimental materials. The trial was established according to factorial randomized block design with four replications. Seed cottons obtained from the trial were ginned in the rollergin and sawgin machines. In the obtained lint cotton samples, a number of fiber characteristics were determined by using HVI and AFIS fiber analysis devices. Ginnig outturn (38.6%), fiber length (30.21 mm), uniformity index (86.02%), fiber strength (31.76 g tex-1), spinning consistency index (SCI) (104.68) determined by using rollergin system were found higher than ones determined by using sawgin system (respectivelly 37.2%, 29.78 mm, 84.61%, 30.97 g tex-1, 94.50). Short fiber index (3.47%) and nep count (59.40 number g-1) obtained from rollergin system were found lower than ones obtained from sawgin system (respectivelly 4.38% and 119.34 number g-1). As a result it can be said that the rollergin method has positive effect on ginnig outturn, fiber length, uniformity index, fiber strength, spinning consistency index, short fiber index and nep count. When fiber length, fiber strength, spinning consistency index, nep size are considered together the best variety was Lydia cv. (respectivelly 30.87 mm, 32.56 g tex-1, 104.25, 675.63 μm). Ginning outturn, uniformity index, short fiber index, total particule number, dust particule number and trash count are considered together the best variety was Erşan-92 cv. (respectivelly 39.4%, 86.02%, 3.48%, 231.4 number g-1, 206.3 number g-1, 25.13 number g-1). For fiber fineness the best varieties were BA 119 and Maraş-92 cv. (respectivelly 4.78 mic. and 4.80 mic.).

Studies on the adaptability and stability are fundamental for plant breeding as they are an alternative to reduce the effects of genotypes x environments interaction (GxE). Moreover, they help identify cultivars with predictable behavior, which are responsive to environmental improvements, subsidizing cultivar recommendation. This study aimed to investigate the genotypes x environments interaction in cotton genotypes grown in the Brazilian Cerrado and identify genotypes for favorable and unfavorable environments. During the 2013/2014 and 2014/2015 seasons, 19 competition trials were carried out with cotton in a randomized block design, with 12 treatments, and four replications. The traits cotton seed yield, fiber percentage, fiber length, and fiber strength were evaluated. Results revealed significant GxE interaction for all the fiber traits evaluated. Genotype BRS 369 RF revealed general adaptability and high predictability for the fiber traits evaluated.

AbstractIn cotton–wheat cropping system of Pakistan, wheat (Triticum aestivum L.) is harvested in late April; however, the optimum sowing time of Bt cotton is mid-March. This indicates a time difference of 4–6 weeks between the harvest of wheat and cotton sowing. It is hypothesized that this overlapping period may be managed by transplanting cotton seedlings (30–45 days old) in late April, after the harvest of wheat due to better performance of already established seedlings. To this end, this study was conducted to evaluate the allometric traits and fiber quality of transplanted Bt cotton after harvesting wheat in the cotton–wheat cropping system. The Bt cotton–wheat cropping systems were flat sown wheat (FSW)–conventionally tilled cotton, FSW–zero tilled cotton, ridge sown wheat–ridge transplanted cotton using 30- and 45-days-old seedlings, and bed sown wheat (BSW)–bed transplanted cotton (BTC) also using 30- and 45-days-old seedlings. The study was conducted at Vehari and Multan in Punjab, Pakistan. Bt cotton in BSW–BTC with 45-days-old seedlings showed better performance for allometric (leaf area index; (LAI), net assimilation rate; (NAR), and crop growth rate; (CGR)), seed cotton yield, and fiber traits (fiber uniformity, fiber length, fiber strength, and fiber fineness) in comparison to other treatments. Most of the fiber quality traits were positively correlated with allometric traits and biological yield (dry matter yield at maturity) at both locations, except correlations of CGR and LAI with fiber fineness and fiber length and NAR with fiber length. As plant growth and fiber quality of transplanted cotton was significantly higher than conventionally grown cotton, our data indicate transplanting is an interesting management practice for improving productivity in wheat–cotton cropping systems.

This study aims to determine the variation of fiber quality in cotton varieties produced in the Southeastern Anatolia Region and Sanliurfa, Diyarbakir provinces. 1090 fiber samples were obtained from 6 cotton varieties (Lima, Stoneville 468, Candia and Babylon for Sanliurfa, Lima, Stoneville 468, Lodos and Gloria for Diyarbakir) collected from ginning factories in Sanliurfa and Diyarbakir. Statistical analyzes were done with HVI device and obtained data were analyzed by using Excel and TOTEMSTAT programs. In the frequency distribution, cotton varieties of the region are in the medium and long fiber group in terms of fiber length. They were in the medium (only two samples), strong and very strong group in terms of fiber strength. They were generally in the medium and thick group in terms of fiber fineness (micronaire). In terms of fiber uniformity index, the majority of the fibers were in the middle group. In terms of short fiber index, most of the fibers were in the very low and low groups. The majority of the samples were in the high and medium group in terms of fiber elongation, in the mature and very mature group in terms of fiber maturity. In terms of spinning consistency index (SCI) 59,2% of the fibers were between 119,41 and 135,83; 31,3% of them, were between 135,83 and 152,24, 58,2% of the material has a reflectance value of 74 and above. All materials were in white and light-yellow groups in terms of yellowness. It has been observed that the majority of the fibers (66%) are in the low group in terms of trash count. The results obtained from the study of cotton produce of Southeastern Anatolia Region of Turkey has shown that good fiber quality and to meet the demand of textile industry.

Different Populations

This study aimed to evaluate the quantitative and qualitative aspects of production in different populations of cotton cultivars. Ten cultivars were evaluated annually in four plant populations. A randomized block design with split plots and three replicates was used. The cultivars were placed in plots, and the plant populations were placed in the subplots. The following characteristics were evaluated: fiber percentage, fiber yield (kg ha-1), fiber length (mm), the micronaire index, the short fiber index (%), and fiber resistance (gf tex-1). In general, the effect of cultivar was much more important than that of the plant population. These results agree with those obtained by several other authors who have claimed that cotton has a high capacity to adapt to certain population ranges. Thus, considering current seed prices, smaller populations can be used without affecting productivity.

Sembilan hasil persilangan kapas tahun 1997 dan 1998 yang melibatkan dua tetua dari Amerika Serikat (Deltapine Acala 90 dan Deltapine 5690), tiga tetua dari India (LRA 5166, Pusa 1, dan SRT 1), dan satu tetua dari Asia Tengah (Tashkent 2) telah melalui tujuh pengujian di Jawa Timur, Nusa Tenggara Barat, dan Sulawesi Selatan untuk menilai potensi produksi, mutu serat, dan tingkat ketahanan terhadap beberapa hama di lahan tadah hujan dengan atau tanpa diproteksi dengan insektisida. Perlakuan disusun dalam rancangan acak kelompok (RAK) yang diulang tiga kali dalam kondisi diproteksi ataupun tanpa diproteksi dengan insektisida pada petak-petak percobaan berukuran 40-50 m2 dengan jarak tanam (100 x 25) cm. Pengendalian hama pada ulanganulangan yang diproteksi dengan insektisida adalah penambahan insektisida benih Imidachloprit 10 ml/kg benih dan pengendalian hama H. armigera sebanyak 5-6 kali menggunakan pestisida nabati Organeem (Azadirachtin 1%). Hasil pengujian menunjukkan bahwa Kanesia 10 – Kanesia 13 mampu berproduksi lebih tinggi apabila diproteksi dengan insektisida dengan potensi produksi berturut-turut 19,32, 21,75, 17,05, dan 21,7% lebih tinggi dari Kanesia 8, dan rata-rata produktivitas berturut-turut adalah 2.457,2, 2.507,3, 2.410,5, dan 2.506,8 kg kapas berbiji per hektar. Kanesia 10 dan Kanesia 11 memiliki kandungan serat berturut-turut 27,2% dan 8,11% lebih tinggi dibandingkan Kanesia 8. Pada rekayasa Kanesia 10 - Kanesia 13 ini tidak diperoleh kemajuan genetik yang nyata pada parameter mutu serat, akan tetapi mutu serat dari empat galur tersebut di atas memenuhi kriteria industri tekstil yaitu dengan rata-rata karakteristik mutu serat yaitu panjang serat 26,92 – 29,34 mm, kekuatan 27,13 – 29,50 g/tex, kehalusan 4,38-5,08 micronaire, dan keseragaman serat 83,3 – 84,6%. Kata kunci : Gossypium hirsutum, kemajuan genetik, produktivitas, mutu serat ABSTRACT Kanesia 10- Kanesia 13: Four New High Yielding Cotton Varieties The cotton breeding program is focusing on the increase of productivity and fiber properties. The 1997 and 1998 crossing program involving two parents introduced from the United States of America (Deltapine Acala 90 and Deltapine 5690), three parents introduced from India (LRA 5166, Pusa 1, and SRT 1), and one variety originated from Central Asia (Tashkent 2), have resulted in nine crosses which had been tested in seven locations at East Java, West Nusa Tenggara, and South Sulawesi to evaluate their yield potentials, fiber properties, and resistance level to insect pests on rainfed areas with or without protection. Experiments were arranged in randomized block design (RBD) with three replications either with or without insecticide spray on 40-50 m2 plots with (100 x 25) cm planting space. Insect controls were done by treating cotton seed with 10 ml Imidachloprit per kg seed and 5-6 applications of botanical pesticide Organeem (Azadirachtin 1%). Experimental results showed that Kanesia 10-Kanesia 13 yield better when insects are controlled. Their yield potentials are 19.32, 21.75, 17.05, and 21.7% higher than Kanesia 8, respectively, and means of yield are 2,457.2, 2,507.3, 2,410.5, and 2,506.8 kg seed cotton, respectively. Kanesia 10 and Kanesia 11 have 27.2 and 8.11% higher gin turnout, respectively than Kanesia 8. On the engineering of Kanesia 10-Kanesia 13, there is no improvement on the fiber properties, although they meet the textile industries’ criteria i.e. staple length 26.92 – 29.34 mm, fiber strength 27.13 – 29.50 g/tex, fiber fineness 4.38-5.08 micronaire, and uniformity ratio 83.3 – 84.6%.

Positive Effect

Achieving high yields is a challenge for sugarcane producers due to the diverse environmental conditions to which the crop is subjected. In tropical and subtropical regions, where sugarcane is typically cultivated, crop diseases are common. This necessitates the development of disease management techniques. Among these techniques, chemical control is of particular significance due to the development of new antifungal agents, such as pyraclostrobin. For some crops, pyraclostrobin has a positive influence on yield due to its effects on plant physiology. The aim of this study was to evaluate the physiological responses and yield of three sugarcane cultivars treated with the fungicide, pyraclostrobin. The experiment was performed in a randomized block design (RBD) with a split-plot arrangement; the variables analyzed were the application or non-application of fungicide in the plots and, in the subplots, the evaluation times after fungicide application. Both the rate of photosynthesis and the antioxidant enzyme (Superoxide Dismutase, Catalase and Ascorbate Peroxidades) activity increased in plants treated with fungicide in comparison to untreated plants, and in the RB855156 cultivar the stomatal conductance, transpiration, and nocturnal respiratory rate were increased. Furthermore, application of pyraclostrobin increased stalk yield and the green biomass index in the RB855156 and RB86751 sugarcane cultivars. In certain cultivars of sugarcane, application of pyraclostrobin leads to an increased yield.

Abstract Nine cotton genotypes, comprised of four non Bt males (CIM-1100, CIM-506, FH-942 and FH-900), five Bt female genotypes (FH-113, FH-114, MNH- 886, AA-703 and IR-3701) and their 20 crosses were screened in order to evaluate their response to Cotton leaf curl virus symptoms through epidemiology in the field and greenhouse. The 20 crosses among their nine parents were sown in two replications under randomized complete block design, during 2013 and 2014. The mean squares were significant for all traits indicating that both additive and non-additive genes control the characters, but non-additive genes were more important because, variance of dominant genes were higher than additive genes. In our test, FH-900 showed the best performance against CLCuV, number of lobes per boll and seed yield. The CIM- 1100 genotype performed well in boll weight, fiber strength and fiber fineness, whereas CIM-506 was good for plant height, number of sympodial branches and ginning. Maximum boll number, seed index and fiber length were shown by FH-942. Among lines, MNH886, FH-113, IR-3701 and FH-114 exhibited the best general combination for many traits. Hence, parents were preferred for hybridization program to improve the majority of characters. Hybrids FH-113 × FH-942, MNH-886 × CIM-1100, MNH-886 × FH-942, IR-3701 × CIM-506, AA-703 × CIM-1100, FH-114 × FH-942, FH-114 × CIM-1100 and MNH-886 × FH- 900 was best in specific combinations for different traits, especially against CLCuV. The results indicated that to increase resistance against CLCuV, hybrids should be exploited to develop CLCuV resistance.

Seven sources of cotton representing a wide range of fiber properties were roller ginned, saw ginned, or saw ginned plus processed through tandem saw lint cleaners or through an aggressive carding-type cleaner (Cottonmaster1). Lint cleaner induced changes in fiber length and nep count were compared to fiber property measurements from roller ginned samples. Fiber length deterioration from saw ginning was negatively correlated with fiber strength. Fiber breakage in lint cleaning was positively correlated with fiber fineness. Resistance to fiber length damage in ginning was explained best by fiber strength and fineness, or an estimate of individual fiber strength. Initial and final nep level were related to fineness, nonlint content, and upper quartile length, but an increase in neps due to lint cleaning had no significant relationship to fiber properties.

This experiment was conducted in a randomized block design with three replications at Bangladesh Agricultural Research Institute, Gazipur-1701 during the rabi season of 2010 with 25 maize inbred lines. Correlation and path coefficient analysis were done for yield and some other traits. Genotypic variations were observed for ear height and grains/row. The highest broad sense heritability (h2b) was observed for yield/plant followed by ear height and 1000- grain weight. Maximum genetic advance in percentage of mean (GA) was recorded for yield/plant (92.652) and ear height (75.87). The yield/plant showed significant positive genotypic correlation (rg) with cob diameter (0.440) and grains/row (0.265). Significant negative correlation was observed between ear height and yield and also for days to 50% tasseling. The highest direct positive effect was obtained for rows/cob. These studies suggest that cob diameter, row per cob, grains/row and ear height were the most important yield contributing factors and an attempt should, therefore, be made for an effective selection of these traits.

Hybrid Cultivar

Tropical soils are highly weathered, acidic, and low in silicon (Si) availability for plants. Si has been considered an essential nutrient for many grasses. Urochloa Convert HD364 is classified as a forage plant that accumulates Si, but the accumulation of this nutrient in the leaf can influence qualitative characteristics, fiber quality, plant architecture, and development of forage. In this study, we aimed to evaluate the production and nutritive value of Urochloa hybrid cultivar Convert HD364 (CIAT 36087) grown from soils collected in the state of Paraná, Brazil. The experiment was carried out in a greenhouse using 8-L plastic pots and three types of soil. Treatments were arranged in a randomized block design in a 3 × 5 factorial: three soils [Rhodic Acrudox (Ox1), Rhodic Hapludox (Ox2) and Arenic Hapludult (Ult)] and five silicate rates (0, 1, 2, 4 and 6 Mg ha-1 of calcium/magnesium silicate), with four replications. Application of CaSiO3 to the soil increases the concentration of Si in the leaves of Urochloa Convert HD364. The dry matter, crude protein and mineral matter, fiber quality, and digestibility of Urochloa were not influenced by the increase in Si levels in the leaves until 45 days after seeding. Forty-five days after planting, CaSiO3 did not interfere with the growth characteristics and production of Urochloa Convert HD364. There is no evidence that the increased Si levels in the leaf affected the production and nutritive value, especially fiber quality of Urochloa Convert HD364 until 45 days after sedding.
