Phenotypic diversity, heritability, and association of characters in sugarcane genotypes at Metehara Sugar Estate, Ethiopia

Genetic variability, correlation studies and path analysis in sugarcane early clones

“…Other traits showing positive direct effects were CCS (t/ha), number of millable canes at harvest and number of shoots at 240 DAP (Table 4). Similar findings were reported by Tena et al (2023) [19] exhibiting cane yield had significant positive correlation with tiller number 3 and 4 months after planting, number of millable cane, single cane weight, stem diameter, stalk height, number of internodes, internode length, sugar yield, pol percent, purity percent and recoverable sugar. They also indicated that single cane weight and number of millable canes were the major contributors to cane yield.…”

“…It is likely to occur because phenotypic variations contain both genotypic and environmental components and delineates genotypes by environment interaction in the expression of all the traits. This was confirmed by Sharma et al (2023) [17] , Barreto et al (2021) [4] and Tena et al (2023) [19] .…”

A simplified approach to satellite-based monitoring system of sugarcane plantation to manage yield decline at Wonji-Shoa Sugar Estate, central Ethiopia

“…Thus, there are possibilities of using LCVIs to generate information on the yield components of sugarcane, particularly plant density and height. As these parameters greatly determine the final yield of sugarcane [ 60 , 77 , 90 ], LCVIs can thus be employed to predict the cane yield. Furthermore, using LCVIs, it is possible to estimate various parameters of sugarcane, the costs of which are prohibitively high if done through conventional means.…”

“…The second approach focused on evaluating LCVIs for their degree of association with yield components of sugarcane (plant density, height, and diameter). These yield components have a significant association with cane yield and hence can show the performance (health) of the cane [ 60 ]. Thus, spectral VIs are expected to correlate with these yield components.…”
