“…Such biometrics characters correlate directly with yield, which means that superior biometric characteristics imply high sucrose accumulation in the sugarcane. Here, high sucrose content is a desirable component in sugarcane stalks (Shikanda et al, 2017), and its stability such as 1 st and 2 nd ratooning plantations determines the superiority. This study aimed to evaluate the stability of the yield component of ratooning sugarcane resulting from mutations.…”

Increasing national sugar production can be done by developing new varieties of sugarcane varieties with high potential yields. To ensure profitability and sustainability, however, the new varieties should be accompanied by data on their ratooning ability. This study aimed to evaluate the stability of the yield component of ratooning sugarcane resulting from mutations. The experiment was arranged using a factorial randomized complete block design with the first factor being four genotypes of sugarcane (G) consisting of three mutant genotypes with codes M3.2, M3.3, M3.4 and one original Bululawang genotype (BL). The second factor was ratooning (K) which consisted of three levels, namely first plant (TP), first ratoon (TK1) and second ratoon (TK2). The combination of treatments was repeated 4 times so that 48 unit combinations were obtained. One unit consisted of 28 cane clumps divided into 4 rows. The results showed that the ratooning factor had a significant impact on the value of the proportion of sucrose produced by the mutant sugar cane genotype. The ratooning ability of mutant genotypes to produce sucrose was recorded above 75%. All genotypes of mutant had superior characters compared to non-mutant based on stalk weight and percentage of sucrose. Keywords: Bululawang, morphology, mutant, ratoon, sugar

This study was initiated with the objective of determining the effect of different harvesting ages (12, 13, 14, 15, and 16 months) on yield and yield components of selected the two sugar cane varieties (B52/298 and NCo 334) grown in Finchaa sugar factory, Oromia, Ethiopia. A field experiment was conducted at Finchaa sugarcane plantation using a randomized complete block design of a factorial arrangement of 2 × 5 with three replications. The data were performed using SAS version 9.3, and a significant difference was considered at p ≤ 0.05 . The results showed that B52/298 variety had a higher estimated recoverable sucrose than NCo 334 variety. The results also indicated that as harvesting ages increase yield, yield components of sugar cane quality are increased. The maximum sugar yield of 1.89-ton ha-1 month-1 was obtained at the harvesting age of 15 months. There was a significant difference ( p < 0.05 ) between harvesting age and sugarcane varieties on cane yield, sugar yield, brix percent juice, pol percent, and recoverable sugar. Generally, the findings imply that as harvesting ages in month increase, brix percent juice, estimated recoverable sucrose, and sucrose percentage in both varieties were simultaneously increased. The findings suggested that B52/298 sugar cane variety with harvesting age between 14 and 16 is highly recommended to obtain optimum sugar cane yield and yield components at the tropical areas of Finchaa sugar factory.

This study was conducted to estimate broad sense heritability, genetic advance, GE interactions and correlations among quality traits in sugarcane clones in western Kenya. Thirteen sugarcane promising clones and one check cultivar were evaluated plant and ratoon crops in three locations under rain fed conditions using the randomised complete block design with three replications. Analysis of variance showed significant differences in hand refractometer brix, sucrose content (Pol% cane), juice purity, fire content, sugar yield and brix yield. Sucrose content, fibre content, sugar yield and brix yield exhibited significant genotype × location (GL) interactions. The genotype mean squares exceeded the GE interactions for all the quality traits suggesting that more emphasis should be placed on testing clones in many locations than on testing ratoon crops within locations. High genetic coefficient of variation (GCV) was detected for cane yield (8.12%), brix yield (6.39%), sugar yield (5.69%) and sucrose content (3.69%). Broad sense heritability was high for sucrose content (0.712) and moderate for cane yield (0.515), fibre content (0.474), juice purity (0.445) and refractometer brix (0.380). Cane yield (10.3%), brix yield (6.7%), sucrose content (5.5%) and sugar yield (5.4%) showed highest expected genetic advance. The results indicated that these traits may respond positively to selection and present opportunities for improvement through breeding. High genetic correlation (r g =0.998) between refractometer brix and sucrose content suggest that selection for refractometer brix can be effective in identifying varieties with high sucrose content.
