Topical Applications

Single topical applications of monosodium methanearsonate (MSMA) affected cotton (Gossypium hirsutumL.) growth more than did similar disodium methanearsonate (DSMA) applications. There was usually no difference in yield among rates and dates with single applications of DSMA. Single applications of MSMA at later dates and higher rates reduced yields. Repeated topical applications of MSMA reduced yields and affected boll weight, lint percentage, number of seed per boll, and fiber fineness as compared with these properties of cotton treated once with MSMA. Response of cotton to MSMA was related to the number of applications and rate of herbicide. Repeated applications of DSMA affected cotton yield, lint percentage, and number of seed per boll less than did MSMA.

Background: Cotton (Gossypium hirsutum L.) is grown in more than sixty countries worldwide. It is an important fiber crop in the world. It plays a vital role in our national economy being the source of earning of foreign exchange, therefore, it is considered to be the backbone of the economy of Pakistan. In Pakistan, millions of families are associated with cotton and textile industry for their livelihood.  Results: In this experiment F2 population of the cross L. A. Frego Bract x CIM-600 and their parents was sown in randomized complete block design with three replications during normal growing season of the year 2014 to sort out best performing genotypes for yield related traits. Analysis of variance (ANOVA) revealed that parental and their F2 population showed significant differences for all the observed agronomic traits (plant height, number of monopodia branches, number of sympodial branches, number of bolls per plant, boll weight, ginning out turn, bract type, boll shape, beak size, seed cotton yield, staple length, fiber strength and fiber fineness). Estimation of correlation revealed that seed cotton yield was found positively correlated sympodial branches, fiber fineness and boll weight while ginning out turn, bract type, beak size, staple length and fiber strength were negatively associated with seed cotton yield. Epistasis was not found to be involved in any of the traits. Conclusion:  The correlation and genetics study of various yield related traits provides us useful information for effective selection and sustainable breeding programs. Estimation of broad sense heritability ( ) in F2 populations for different traits vary as following order; ginning out turn>plant height>seed cotton yield>sympodia branches>fiber length>fiber strength>bolls per plant>monopodia branches>boll weight>fiber fineness with heritability 0.90, 0.79, 0.78, 0.75, 0.73, 0.71 0.67, 0.64, 0.63 and 0.50 respectively. Results suggested form heritability and correlation that these traits can be improved either through appropriate selection method or hybrid breeding programme.

The experiment was laid to analyze genetic features, genotypic and phenotypic correlation coefficients, path analysis with regression analysis among yield contributing traits in a selected F3 populations of upland cotton including parents. In this research experiment ANOVA showed significant difference among all individual plants in F3 populations. Monopodia per plant and bolls per plant possessed maximum value of PCV% and GCV%. Maximum broad sense heritability (≥ 90) was found in all recorded traits except seeds per boll, fiber length and lint percentage. Correlation studies revealed that Seed cotton yield positively correlated with all yield contributing traits i.e. plant height, monopodial branches per plant, Number of bolls per plant, boll weight, lint weight, seed index, lint index, seeds per boll, fiber fineness, fiber strength and fiber uniformity at both genotypic and phenotypic level whereas it depicted negative relationship with staple length. Path coefficient analysis showed that maximum direct positive effect was found of lint weight (2.6005) on seed cotton yield followed fiber fineness (1.2628), seed index (1.1449) and bolls per plant (1.0027). Regression study exhibited that maximum value of R2 for lint weight (0.9509) and boll weight (0.3735) depicted that 95.09% and 37.35% variation in the seed cotton yield, due to its relationship with lint weight and boll weight. It is concluded that there is a great genetic potential in F3 populations for mostly yield contributing traits for further enhancing yield. So those traits should be used as selection criteria during breeding for yield.

Rates of trifluralin (α,α,α-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine) applied preplanting were combined with rates of diuron [3-(3,4-dichlorophenyl)-1,1-dimethylurea] applied postemergence in cotton (Gossypium hirsutumL. ‘Deltapine 16’). In another experiment, two levels of these herbicides were applied in three populations of cotton. All herbicide combinations improved weed control, compared to that of cultivated checks. Applications of 0.28, 0.42, and 0.56 kg/ha of trifluralin combined with 0.56 kg/ha of diuron controlled annual weeds and produced the highest cotton yields. Herbicide treatments had more influence than crop spacing on weed control and crop yield. Weed competition on cultivated checks affected boll weight, seed per boll, and fiber fineness.

Abstract Background Cotton is known for its fiber and it is grown in tropical and sub-tropical areas of the world. It has a significant role in GDP of Pakistan. Therefore, present two years research was conducted to estimate heritability and association among various yield contributing parameters of cotton. The selected genotypes of cotton were hybridized in green house of the department. The F 0 cotton seed along with parents were planted in the field conditions during May, 2018. The sowing of this experiment was completed in three replications followed by RCBD. The data was recorded at maturity for various agronomic traits including plant height, number of bolls per plant, number of sympodial branches per plant, seed cotton yield, boll weight, seed index, ginning out turn, fiber length, fiber strength, and fiber fineness. Level of significance of data was computed by ANOVA to assess the difference among cotton genotypes which was used for estimation of heritability and correlation analysis among the related traits. Results Association analysis revealed that seed cotton yield had significant positive relationship with plant height, number of bolls per plant, number of sympodial branches per plant, ginning out turn, staple length and fiber strength. Staple length and fiber strength were negatively linked with each other. Estimates of heritability were high for all observed traits except number of sympodial branches per plant and boll weight. Conclusion The parent IUB-222 was found best for plant height, number of bolls per plant, boll weight, ginning out turn, seed cotton yield and seed index. NIAB-414 and VH-367 were identified best parents for fiber length, strength and fineness. Among crosses NIAB-414 × IUB-222 was best for number of bolls per plant, seed index, seed cotton yield and fiber fineness. Whereas, cross NIAB-414 × CIM-632 was good for plant height. The combination of A555 × CIM-632 was best for number of sympodial branches per plant, boll weight, fiber length and strength. VH-367 × CIM-632 proved best for ginning out turn. The correlation results from this study would be helpful to breed cotton cultivars with good yield and quality characters. Broad sense heritability was high for all of parameters which provides the strong evidence that selection in early generations can improve the performance of these traits.

The objective of the present study was to estimate general combining ability (GCA) of the parents and specific combining ability (SCA) of crosses for the development of high yielding cotton varieties. The study was carried out at the experimental area of Department of Plant Breeding and Genetics, University of Agriculture, Faisalabad. A line × tester analysis was made to identify the superior general and specific combiners for seed cotton yield and fiber quality traits in upland cotton. Five lines/females (FH-114, FH-1000, CIM-448, CIM-707, NIAB-111) and three testers/males (TH-41-83, Cocker-307 and Allepo-41) were crossed to develop 15 F1 hybrids. These genotypes were evaluated along with parents in RCBD with three replications. The general combining ability (GCA) and specific combining ability (SCA) mean squares for seed cotton yield, lint percentage, fiber fineness, fiber strength and fiber length were significant. The fiber fineness showed greater importance of additive gene effect while seed cotton yield, lint percentage, fiber strength and fiber length exhibited non additive genetic effects. Parents FH-114 and NIAB-111 among lines and COKER-307 from testers were found as good general combiners for most of the traits. Hence, these parents proved worth to be used in hybridization and selection program for extracting desirable plants from segregating population. F1 crosses CIM-707 × COKER-307, CIM-707 × ALLEPO-41 and FH-1000 × COKER-307, by and large, exhibited their superiority for all traits studied and were noted as the best specific combiners. Therefore, these crosses may be preferred to improve several traits simultaneously by selection or may be used for hybrid cotton crop development

<p>ABSTRACT<br />Coloured cotton has been used since 3400-2300 BC. Historically, it has been used prior to allotetraploid cotton which are now planted (G. hirsutum dan G. barbadense) of which some have brown and green fiber. The use of coloured cotton is environmentally friendly, and the demand for it will be increasing in relation with the increased demand of organic cotton. The research was aiming to evaluate of Productivity, Fiber Fineness, and Tolerance to Insect Pests ofF7 promising cotton lineswith brown fiber for the development of national cotton new varieties with brown fiber. The experiment was carried out at Pasirian Experimental Station at Lumajang on Januari-December 2013. 14 F7 lines resulted from 2006 crosses and two control varieties were tested in Randomised Blocked Design. There were two unit tests, the spray and unspray test, each was replicated three times. Plot size was 3 x 10m2 with plant spacing was made of 100 x 25 cm in which one single plant per hole was maintained. observation was done on growth and generative components, seed cotton yield, and field tolerance component. Experimental result showed that line 06063/5 was consistently shown high seed cotton yield under spray (2348,3 kg/ha) and unspray conditions (2372,8 kg/ha). Under unspray condition, there were four promising lines which were yielded higher that the best control varieties (Kanesia 10, 2197,2 kg/ha), i.e. 06063/5 (2372,80 kg/ha), 06067/3 (2235,0 kg/ha), 06062/3 (2255,60 kg/ha), and 06066/2 (2383,90 kg/ha). In addition, the best line showingthe highest field tolerance index was 06066/2 (110,5%). There were only two lines which had fiber length of ≥ 1 inch (25,4 mm), i.e. 06067/4 and 06062/1. It terms of fiber strength, genetic improvement achieved was ranging from 0,81 to 11,54% better than Kanesia 10, but 8,11 – 17,64% worse than Kanesia 8. Nine lines which had their fiber fineness 3,0 – 3,8 mic which are met the industry’s demand.<br />Keywords: Gossypium hirsutum L., coloured cotton, productivity, field tolerance index</p><p> </p><p>EVALUASI PRODUKTIVITAS, MUTU SERAT, DAN KETAHANAN TERHADAP HAMA GALUR-GALUR F7 KAPAS BE RSERAT COKLAT</p><p>ABSTRAK<br />Kapas dengan serat berwarna non-putih telah digunakan sejak tahun<br />3400-2300 sebelum Masehi.

Long-term conservation tillage and straw incorporation are reported to improve the soil health, growth, and yield traits of crops; however, little is known regarding the optimal nitrogen (N) supply under conservation tillage with straw incorporation. The present study evaluated the effects of conservation tillage practices (ZTsas: zero tillage plus wheat straw on the soil surface as such, and MTsi: minimum tillage plus wheat straw incorporated) and different N application rates (50, 100, 150, and 200 kg ha−1) on the yield and quality traits of cotton and soil characteristics in a five-year field experiment. The results showed that ZTsas produced a higher number of bolls per plant, boll weight, seed cotton yield, 100-seed weight, ginning out-turn (GOT), fiber length, and strength than MTsi. Among different N application rates, the maximum number of bolls per plant, boll weight, seed cotton yield, GOT, 100-seed weight, fiber length, strength, and micronaire were recorded at 150 kg N ha−1. Averaged over the years, tillage × N revealed that ZTsas had a higher boll number plant−1, boll weight, 100-seed weight, GOT, fiber length, and strength with N application at 150 kg ha−1, as compared to other tillage systems. Based on the statistical results, there is no significant difference in total soil N and soil organic matter among different N rates. Further, compared to MTsi, ZTsas recorded higher soil organic matter (SOM, 8%), total soil N (TSN, 29%), water-stable aggregates (WSA, 8%), and mean weight diameter (MWD, 28.5%), particularly when the N application of 150 kg ha−1. The fiber fineness showed that ZTsas had no adverse impact on fiber fineness compared with MTsi. These results indicate that ZTsas with 150 kg N ha−1 may be the optimum and most sustainable approach to improve cotton yield and soil quality in the wheat–cotton system.
