“…By contrast testers appear to be more important for variation in number of seed cotton yield and revealed the preponderance paternal influence for this trait, the contribution of maternal and paternal influence was relatively higher for variation in lint percentage, fiber strength and fiber length. Similar results were obtained in the previous studies (Khokhar et al, 2018;Bakhsh et al, 2019).…”

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

“…Sahito et al (2015) showed that all the growth and yield components of cotton were significantly (P < 0.01) affected by varieties and irrigation frequencies. Bakhsh et al (2019) noted that water stress caused a reduction of 14% in days to first flower formation, 27% in number of bolls/ plants, 14% in boll weight and 37% in seed cotton yield.…”

Furthermore, fiber quality was significantly affected by drought levels (Gao et al, 2020).…”

Drought stress is a serious abiotic factor that adversely affects cotton yield and fiber properties. The objectives of this study were to screen several genotypes of cotton belong to Gossypium barbadense L. for drought tolerance, study drought indices, correlations, and path-coefficient analysis. Fourteen long-staple kinds of cottons cultivated, and obsolete cultivars were screened for drought tolerance at normal irrigation and drought-stressed experiments for two years. Mean squares indicated significant (p ≤ 0.01) differences among genotypes in the separate and combined analysis. The effect of years showed significant (p≤ 0.05 to p≤ 0.01) differences in most cases. The interaction of genotypes by years was significant for all traits except few cases. The reduction % caused by drought stress in SCY/P ranged from 31.44 to 39.39 with an average of 33.93. Among ten tolerant indices STI, MP, GMP, HM and DI could be considered the best tolerant indices to detect both of tolerant and susceptible genotypes. The correlation of SCY/P under normal irrigation was high with LY/P, Lint %, NB/P, LI and BW, moderate with NS/B and upper half mean length, and low with DFF, Pressley index and negative with Micronaire reading. However, the picture was different under drought stress, in which drought affected lint rather than seeds. The direct and indirect effects of SCY/P components varied greatly under both environments, and LY/P, NB/P and NS/B should be considered as selection indices under normal irrigation, NB/P and NS/B under stress when selection practiced for SCY/P.

“…The cotton crop of different areas is an efficiently vital fibrous crop of Pakistan (Rehman et al, 2016). Many factors like floods, heavy monsoon, infestation of sucking insect pests and cotton leaf curl virus (CLCV) disease have resulted a decline in 13.4% of cotton area during the years 2010-11 (Bakhsh et al, 2019;Egler et al, 2012;Guedes et al, 2020).…”

Monitoring of Insecticides resistance against cotton Jassid (Amrasca biguttutla biguttutla) under laboratory conditions

Development of insecticides resistance mainly hinge with managements techniques for the control of Jassid, Amrasca biguttutla biguttutla. Five insecticides were applied against field collected and laboratory rared jassid populations during the years of 2017 to 2019 to profile their resistance level against field population of jassid through leaf dip method. Very low resistance level was found in jassid against confidor whereas high level of resistance was observed by pyriproxyfen against other test insecticides. Gradual resistance was observed against diafenthiuron. It is concluded that for the management of Jassid repetition of same insecticide should be avoided. The use of confidor may be reduced to overcome resistance against Jassid.
