“…Knowledge on the nature and the magnitude of variability present in the genetic material is therefore of prime importance for breeders to conduct an effective selection program. Coefficients of variation along with heritability as well as genetic advance are very essential to improve any trait of sugarcane because this would help in knowing whether or not the desired objective can be achieved from the material to be investigated [18].…”

The objective of the study was to determine the best performing sugarcane genotypes tested at early selection stage under sprinkler irrigation, in comparison with a check variety (R579). The experiment was designed following a randomized complete block (RCB) with 21 cane genotypes in three replications. Each plot consisted of five dual rows of ten meters with 0.5 and 1.90 m of inter-row spacing, i.e. 95 m 2 per plot and about 6,000 m 2 for the whole experiment. It was carried out on a commercial sugarcane plantation of Ferké 2 located in the northern part of the country, over two seasons (plant cane and first ratoon) as an early-season crop from, November 18, 2016 to November 15, 2018. Over each micro-plot, data based on different agro-morphological traits were collected at harvest from three central dual rows. The study showed that most relevant traits in genotype clustering were related to juice quality (recoverable sucrose, sucrose content, purity), yields and yield components (millable stalk number/ha, stalk height, stalk diameter, internode number). Based on sugar yields, four genotypes equivalent to the check (R579), namely KQ228, R97-6177, R99-4064 and KQ236, were found promising for the next advanced selection stage with, respectively, 19.2, 17.7, 17.3 and 16.9 t sugar/ha. Their cane yield performances ranged from 147.7 to 170.8 t/ha compared to 170.7 for the check and belong to 3 clusters genotypes over the eight determined. Not only sugar yield, but also flowering rate, stem borer infestation rate and number of tillers per hectare were found as the most relevant agro-morphological traits in the genetic variation of sugarcane genotypes tested.

“…Such negative correlation existed between average stalk height and the number of millable stalks/ha (r=-0.81). As reported by several researchers [30,43], strong and positive genotypic correlations indicate that selection based on single stalk weight, internode number and millable stalk number could lead to improvement in agronomic traits like stalk diameter, stalk height and yield traits.…”

“…Average maximum and minimum daily air temperatures are 32.5 and 21°C, respectively. To meet sugarcane crop water requirements, the total amount of irrigation water required reaches 700 mm/year [28][29][30]. Background information on both Ferké sugar mill plantations and their main soil units were reported by Péné and Béhou [26].…”

Background:The selection procedure of commercial sugarcane varieties introduced in Ivory Coast involves two different stages. Four varieties pre-selected at the first stage regarding a previous trial were due to be tested at the advanced stage. Aims: The study aimed to determine the best performing sugarcane genotypes at the advanced selection stage under sprinkler irrigation, in comparison with to two check varieties (R579, SP70-1006). Methodology: The same field experiment was carried out on two different locations in Ferké 2 sugar estate of Northern Ivory Coast. The experimental design used was a randomized complete block (RCB) with six cane genotypes in four replications. Every plot consisted of five dual rows of ten meters with 0.5 and 1.90 m of inter-row spacing, i.e. 95 m² per plot and about 3000 m² for each experiment. Both experiments were conducted over two seasons (plant cane and first ratoon) as early-season crops from early November, 2017 to mid-December, 2019. Over each micro-plot, data based on different agro-morphological traits were collected at harvest from three central dual rows. JEAI, 42(2): 97-115, 2020; Article no.JEAI.55656 98 Results: The study showed that most relevant traits in genotype clustering were related to juice quality (recoverable sucrose, sucrose content, purity), yields and yield components (Millable stalk number/ha, stalk height, stalk diameter, internode number). Based on sugar yields, two genotypes (N47, ECU01) superior to both check varieties were found promising with, respectively, 13.7 and 13.5 t sugar/ha. Their cane yield performances gave 124 and 123 t/ha, respectively, compared to 126.8 t/ha for the best performing check. Conclusions: Not only sugar yield, but also flowering rate, stem borer infestation rate, stalk diameter, average stalk height and the number of tillers per hectare were found as the most relevant agronomic traits in the genetic variation of sugarcane genotypes tested. It came out also that GxE interactions were highly significant for five different traits, namely, cane and sugar yields, stalk borer infestation rate, fiber content and the average stalk height.

To meet sugarcane crop water requirements, the total amount of irrigation water required reaches 700 mm/year [13][14][15]. Both Ferké sugar mill plantations cover around 15 500 ha with 10 000 ha under irrigation and 3 500 ha of rainfed village plantations, lie mainly on shallow or moderately deep soils built up on granites.…”

Aims: The study aimed to determine the best performing cane genotypes among 29 clones tested under sprinkler irrigation, in comparison with a check variety (R579). Study Design: The experimental design used was a randomized complete block (RCB) with 30 cane genotypes in three replications. Every plot consisted of two dual rows of five meters with 0.5 and 1.90 m of inter-row spacing, i.e. 19 m² per plot and about 600 m² for the whole experiment. Place and Duration of Study: It was carried out on a commercial sugarcane plantation of Ferké 2 located in the northern part of the country, over 10 months as a late season crop from late May 2018 to late March 2019. Methodology: Over each micro-plot, data were collected at harvest from both dual rows consisted of millable stalk number/ha, cane yield, juice quality traits (sucrose, purity, and recoverable sucrose), fiber content, and damaged internodes by stem borer Eldana saccharina. Results: Based on sugar yields, seven cane genotypes were equivalent to the check variety R579 which gave 17.6 t/ha. Their yield performances ranged from 12.2 to 15.4 t of sugar/ha and from 134.2 to 160.8 t of cane/ha compared to 176.0 t/ha for the check. Higher heritability values ranging from 52 to 85% were observed in traits like sugar yield, juice purity, juice sucrose, recoverable sucrose, sucrose percent, fiber content and stem borer infestations. Differences between PCV and GCV for most traits were small, indicating high prospects for genetic progress through selection under conditions of this study. Conclusions: Findings obtained need to be confirmed over the 2019-20 cropping season in first ratoon crop to determine promising cane genotypes for the advanced selection stage.
