“…Crop cycles have a detrimental impact on cane and sugar yields. So, it is critical to search for sugarcane quality related to the ratooning ability to be used as a breeding program selection attribute (Abu-Ellail et al, 2018). The ability of different genotypes of sugarcane to generate successful ratoon crops varies substantially (Srivastava et al, 1993).…”

A field experiment was carried out at El-Mattana Agricultural Research Station, Luxor Governorate, Egypt, during three growing seasons, where sugarcane was grown as a plant cane, 1 st and 2 nd ratoon crops, respectively, to find out the effect of three irrigation water regimes (100, 85, and 70% of the irrigation requirement IR) on productivity of five sugarcane varieties, namely G.T. 54-9, G.2003-47, G.2004-27, G.84-47, and G.99-80. A randomized complete block design with four replications in a split-plot arrangement was used. The results showed that 1 st ratoon crop consumed the most irrigation water, followed by the 2 nd ratoon crop and the plant cane crop. Irrigating at 70% IR was the highest in application efficiency, followed by 100% and 85% IR. The cane and sugar yields decreased with the decrease in the irrigation regime; however, water productivity increased with reduced irrigation regimes. The highest phenotypic (PCV %) and genotypic coefficient of variance (GCV %) values and broad-sense heritability% were recorded for sugar and cane yields in the plant cane and ratoon crops under the studied irrigation water regimes. The results showed a significant difference among the evaluated varieties in ratooning ability (RA) and most studied traits. Sugarcane G.2004-27 and G.2003-47 varieties exhibited higher ratooning ability, recording higher cane and sugar yields in both ratoon crops compared to G.84-47 and G.99-80, which had poor performance concerning the same trait in the 2 nd ratoon crop. This study suggests selecting varieties with high productivity of cane and sugar yields in addition to water deficit tolerance based on traits contributing to the crop that has high PCV%, GCV%, and heritability along with the mean value would be effective. The results suggested planting the G.2004-27 variety under normal and water-deficit conditions, and it can be used as a parent in breeding programs to improve the tolerance of sugarcane varieties to water deficit while recommending planting the G.T.54-9 variety under normal irrigation conditions.

Early Evaluation of New Sugarcane Clones in Two Crop Cycles and Interrelationships Among Yield and Agronomic Traits

Abstract: Selecting and developing new high-yielding cane varieties is crucial to enhance its production and meet the ever-increasing demands of sugar. Twenty sugarcane clones (genotypes) and one check cultivar were grown in a randomized complete block design, with three replications, at Mattana
