Heritability and Correlation among Sugarcane (<i>Saccharum</i> spp.) Yield and Some Agronomic and Sugar Quality Traits in Ethiopia

Abstract

To assess broad sense heritability and phenotypic and genetic correlations among sugarcane yield components, an experiment was conducted at Wonji and Metehara Sugar Estates of Sugar Corporation of Ethiopia during 2012/2013. High broad sense heritability (h 2 ) was detected for stalk diameter (0.730), single cane weight (0.672), millable cane number (0.624), stalk height (0.624) and pol % (0.608), indicating that these traits could be selected for easily. Expected genetic gain of the yield components was moderate to high. All traits had low to high genetic correlations (rg = −0.005 to 0.884) with cane yield and (rg = 0.027 to 0.999) with sugar yield. On average genetic correlations were higher than phenotypic correlations. High Genotypic Coefficient of Variation (GCV), broad sense heritability and expected genetic advance were recorded for stalk diameter, single cane weight and millable cane number. A selection strategy based on these traits could lead to improvement in cane and sugar yield.

Production components of agroindustrial interest of sugarcane varieties under subsurface drip irrigation in semiarid conditions

“…According to Fernandes (2011), soluble solids content is one of the most important quality parameters for the sugarcane industry because it is one of the components that defines the sugar yield. Tena et al (2016) evaluated the correlation between agroindustrial components of sugarcane production and found a positive correlation between soluble solids content and gross sugar percentage, confirming the findings of the present work. The strong and significant positive correlation between juice apparent sucrose content and gross sugar percentage denotes that sugarcane sucrose affects juice sucrose.…”

Study of Genetic Variability among Midlate Maturing Sugarcane Clones for Different Yield and Juice Quality Traits under Waterlogged Condition

“…Similar result were also reported by Tena et al, (2016), They found high broad sense heritability for stalk diameter, single cane weight, millable cane weight, stalk height and pol %. Gowda et al, (2016) reported that cane yield components viz., sugar yield number of millable cane, single cane weight and cane yield showed high heritability but Their result is slightly different for plant height, stalk diameter, brix percentage pol percentage, purity percentage and CCS percentage, This different might be due to environmental variations in expression of these traits.…”

Evaluation of Early Group of Sugarcane Genotypes for Yield & Quality Traits

“…Memon et al, (2005) and Panhwar, et al, (2008) reported great variability among the sugarcane genotypes for cane yield and yield components. Similar results were also reported by Tena et al, (2016), Shikanda et al, (2017), Shitahun et al, (2018) and Singh et al, (2019).…”
