The present research work was designed to estimate genotypic and phenotypic correlation coefficients and path analysis at the genotypic level between seed cotton yield and yield contributing traits in 18 cotton cultivars. The material was sown on 15 th of May to observe association among yield and its related traits. Heritability was estimated to determine the selection criteria under normal growing conditions. The values of phenotypic coefficient of variation (PCV%) were higher in magnitude than the genotypic coefficient of variation (GCV%) for all the traits. Heritability (broad sense) revealed higher estimates for all traits like plant height (98%), cotton leaf curl virus (CLCuV%) (96.8%), nodes to first fruiting branch (95%), bolls per plant (91.5%), sympodia per plant (88.8%), yield (88%) monopodia per plant (84.7%) and for boll weight (82.3%). The results of phenotypic and genotypic correlation showed that sympodia per plant showed positive significant correlation with boll per plant, boll weight and yield at both genotypic and phenotypic levels. Boll weight showed strong association with the yield at both levels. Path coefficient analysis revealed that all traits influenced directly and positively on yield except for bolls per plant. The traits showing strong association along with higher heritability may be considered for selection in future breeding endeavors.
Yield and Plant Characteristics of 200 Different Cotton (Gossypium spp.) Genotypes
IJSES, 2023
The experiment was conducted to determine the yield and plant characteristics (plant height, number of sympodial branches, boll number, seed cotton weight, 100-seed weight, seed cotton yield and seed yield,) of two-hundred different cotton (Gossypium spp.) genotypes in Kahramanmaras (Türkiye) conditions using a randomized complete block design with four replications in 2018 and 2019. At the end of the study, it was determined that there were statistically significant differences among the cotton genotypes for all investigated characteristics. Results of two year average showed that plant height, number of sympodial branches, boll number, seed cotton weight,, 100-seed weight, seed cotton yield and seed yield for cotton genotypes ranged
This study was carried out to determine direct and indirect effects of some characters (single leaf area, leaf SPAD value, number of nods, number of sympodial branches, number of monopodial branches, single boll weight, number of bolls) on seed cotton yield. The experiment was carried out with four cotton varieties, two of which okra-leaf (Adana 98, Siokra 1/4) and two of which normal-leaf (Teks and Stoneville 453) cotton (Gossypium hirsutum L.) and was conducted the randomized block design with 4 replications. In order to increase seed cotton yield in the studies of breeding program and selection orderly leaf SPAD value, number of sympodial branches, single boll weight, number of monopodial branches and number of bolls characters determined that must be high. Results showed that in order to increase seed cotton yield in the studies of breeding program and selection the highness of leaf SPAD value, number of sympodial branches, single boll weight, number of monopodial branches and n...
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.
Phenotypic correlation and path coefficient analysis have been worked out for yield and fiber quality traits in 173 RILs of Gossypium hirsutum L. cotton at Agricultural Research Station, Dharwad, UAS, Dharwad. Number of bolls per plant, boll weight, 2.5% span length and micronaire value were found to be positively correlated with seed cotton yield while days to 50 per cent flowering shown negative correlation. Further partitioning of correlation coefficients into direct and indirect path ways of influences showed that the characters having most influence on seed cotton yield are boll weight and number of bolls per plant, which can be considered while selecting for higher yields.

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.
