“…High variability was recorded for different traits in sugarcane. To make sense of the amount of existing variability in the present clones, range, mean and standard error were calculated [15,16,17] (Table 2). However, range is the crude method of estimation of variability, which indicates observed phenotypic variability only.…”

Sugarcane varietal development is frequently aimed at increasing yield and sucrose quality. Effective crop genetic evolution requires knowledge of the numerous traits that contribute to the present diversity by genetic analysis. Keeping in view, this experiment was conducted using a randomized block design with three replications and the trial consisted of nine mid-late sugarcane genotypes. Data on cane yield and quality traits were used to estimate the genetic variability parameters, heritability, and genetic advance (GA). Analysis of variance revealed highly significant and significant differences for all studied traits. Evaluated characters exhibited different levels of variability, heritability, and genetic advance among the studied genotypes. Low to high phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) were recorded. The moderate GCV and PCV values were found particularly for Sugar Yield at harvest (18.09% and 21.64%) and Cane Yield at harvest (16.62% and 20.14%) respectively, whereas the lowest GCV and PCV (1.43% and 2.26% respectively) manifested for Purity at the 12 months stage. The highest broad sense heritability value manifested for Pol in juice at 12 months stage (%) (86.47%) followed by CCS at 12 months stage (%) (85.43%), while the lowest heritability (35.00%) revealed only for Germination % at 30 DAP. In the present study, high heritability and genetic advance as a percentage of the mean (>50) was recorded for Millable canes at harvest (000/ha) and single cane weight at harvest (kg) indicating a predominance of additive gene action for these characters. Therefore the result of this study suggests the existence of variability for cane yield and quality traits in these sugarcane genotypes, which should be exploited in future breeding.

Aims: To make pragmatic selection of best performing sugar cane clones, it is compulsory to know traits having high values of heritability. Hence, this work was initiated with the aim of estimating genetic parameters of twelve sugarcane clones planted in randomized block design with three replications. The tested clones were significantly different for all most all the traits at 1% and 5% level of significance. Genotypic and phenotypic variance, GCV and PCV, heritability in broad sense (h2) and genetic advance as percent of mean was calculated for all traits taken. Results: Low genotypic variances were obtained as compared to the corresponding phenotypic variances for the traits taken. High GCV and heritability coupled with high genetic advance as percent mean were obtained for Shoots at 240 DAP (Days After Planting) (1000/ha), Single cane weight at harvest (Kg), commercial cane sugar (CCS) at 8 months stage (%), CCS at 10 months stage (%), Sugar yield at harvest (t/ha) and Cane yield at harvest (t/ha). Hence, selections based on these characters are appropriate for varietal improvement.

“…In general terms, the G × E interaction corresponds to the differential response of the genotypes to changes in the environments, thus evidencing the dependence between genetic and environmental effects. The importance of the study on G × E interactions is well-recognized (Kumar et al, 2018). In this context, the cultivars exposed to some kind of stress may show a wide range of complex and variable responses which depend on the genotype's inherent sensitivity to stress (Chen et al, 2012).…”

“…The only trait with negative skewness was sucrose (−0.57). It should be stressed that, along the history of sugarcane breeding, breeding programs have focused on selecting genotypes with increasing ability to accumulate sucrose (Morais et al, 2015;Balsalobre et al, 2016;Kumar et al, 2018). With this in mind and considering that the 20 varieties selected had the ability to yield high sucrose content, a left skewed distribution was expected.…”
