“…This indicates improvement in these characters would simultaneously result in the improvement of cane yield and hence selection based on these characters could be advantageous. These results are in conformation with SanjayKumar and Devendra Kumar (2014) for the number of millable canes;Tena et al (2016), Pandya and. Patel (2017) for the number of millable canes and commercial cane sugar yield.…”

Sugarcane clones were assessed for cane yield and quality traits in Advanced Varietal Trials in I plant, II plant and ratoon crops during 2019-21. Fifteen genotypes along with three standards were evaluated using Randomized Block design with three replications at K. J. Somaiya Institute of Applied Agricultural Research (KIAAR), Sameerwadi, Karnataka. Data were collected on eleven important yield contributing and quality traits. Individual and pooled analysis of variance in two plants and a ratoon crop indicated highly significant differences among the treatments for most of the traits under study. Genotype Co 14016 recorded significantly higher cane yield and numerically higher commercial cane sugar (CCS) yield in AVT II Plant, AVT Ratoon and pooled analysis. Co 14002 variety recorded significantly higher cane and CCS yield over all three standards, (Co 86032, CoC 671 and Co 05103) in II plants. Two varieties, CoN 14002 and CoVC 14062 recorded significantly higher cane and CCS yield over all three standards, (Co 86032, CoC 671 and Co 05103) in only ratoon crop indicating the good ratoonability of these varieties. Character association studies of cane yield with its contributing traits indicated positive significant correlations of the number of shoots (0.346), millable canes (0.591) and CCS yield (0.883) with cane yield. Among the yield parameters, a positive significant association of cane height with the number of tillers, the number of shoots, Brix 0 and Pol% has been observed, indicating the contribution of cane height to yield and quality. The present study demonstrated the superiority of three genotypes viz., Co 14016, Co 14002 and CoVC 14062 for cane yield and quality and scope for indirect selection based on the number of shoots, millable canes and CCS yield in sugarcane breeding.

“…Moreover, path coefficient analysis revealed that number of millable cane and single cane weight had the highest direct effect on cane yield than other traits Kumar, 2014 andAgrawal andKumar, 2018). Single cane weight had the highest positive direct effect on cane yield followed by millable cane number as revealed by Chaudhary andJoshi, 2005 andPandya andPatel, 2017. Path analysis revealed the highest positive direct effect of millable cane number (0.812) on cane yield followed by single cane weight (0.682) (Tena et al, 2016).…”

“…Nonsignificant but positive and weak correlation between weight of millable stalks and brix (0.05) as well as number of millable stalks and stalk height (0.285) were found by Tyagi & Lal (2007). The cane yield was positively and significantly correlated with sugar yield, single stalk weight, number of tillers and stalk length (Swamy Gowda et al, 2016;Tena et al 2016;Pandya &Patel, 2017 andAgrawal &Kumar, 2018).…”

“…Brix had negative effect on sugar recovery while sucrose had positive direct effect on sugar recovery (El-Taib, 2009). Moreover, the stepwise regression revealed that sweetness and purity presented in unique model with R 2 equal to unity (=1) and were superior to determine and selection for sugar yield in sugarcane (Abo-Elwfa et al, 2015;Pandya & Patel, 2017;Agrawal & Kumar, 2018;and Anbanandan et al, 2020).…”

The obtained results could be displayed the effeteness of stepwise regression analysis to determine the strongest trait/s to produce the high sugar, cane yields and sugar recovery in sugarcane. The model which has two independent traits of cane yield (CY) and sugar recovery (SR) resembled to be the fit model for sugar yield and gave R 2 = 1.000 in second and third ratoon crops as well as over both of them. Also, the model which has two independent traits of sugar yield (SY) and sugar recovery (SR) resembled to be the fit model for cane yield and gave R 2 = 1.000 in second and third ratoon crops as well as over both of them. The model included three traits of sucrose (SUC), brix (BR) and pol (PO) with R 2 =1.000 in second ratoon or SUC and BR with R 2 = 0.999 in third and over both ratoons crops, resembled to be the fit model for sugar recovery. High positive and significant estimates of correlation coefficients were recorded between cane yield and each of stalk height, stalk weight, stalk number/fed and sugar yield in all studied ratoon crops. High and positive significant estimates of correlation coefficients were recorded between sugar yield and each of stalk height, stalk weight and stalks number/fed over the two ratoon crops. It is remark result that the traits of brix, purity %, pol and sugar recovery were correlated each other in high significant and positive estimates in both ratoon crops, revealing the high quality traits as important components express high sugar in sugarcane. Pathcoefficient analysis through the second, third and over both of ratoon crops revealed that the stalk weight, stalk number/fed and cane yield had the greatest direct and indirect influences on sugar yield. Moreover, the stalk number and stalk weight had the greatest direct and indirect influences on cane yield. The path coefficient analysis exhibited that sucrose contributed the greatest effects on sugar recovery even direct or indirect effects via pol, brix and purity over the both ratoon crops.

“…A positive and highly significant correlation between cane yield and its components viz., single stalk weight, stalk length and millable cane number was reported (Panhwar et al 2003;Thippeswamy et al, 2003;Chaudhary & Joshi 2005;Kadian et al 2006;Tyagi & Lal 2007;Devendra & Sanjay 2014;Kumar & Kumar 2014;Tena et al 2016;Pandya & Patel, 2017).…”

The present study was carried out in a privet farm in El-Shaghap Region, South Esna of Luxor Governorate, Egypt (latitude of 25.30°N and longitude of 32.30°E). The work was conducted during the two plant-crop seasons of 2017/2018 and 2018/2019 to study the sugarcane planting using bud chips and conventional methods. Four sugarcane varieties G.T. 54-9, G.84-47, G.2003-47 and C.57-14 were tested in this study. The experimental design was a split plot design with four replications. The four varieties were randomly distributed to the main plots and the two planting methods (conventional method and bud chips) assigned as sub-plot (42 m2). Each plot contains six rows with the length of seven meters/row and one meter of row width.The results indicated that unique and high positive estimates of correlation coefficients were recorded between seeding survival % and each of millable cane length, millable cane weight, cane yield/ fed, brix, sucrose content, purity %, sugar recovery %, pol and sugar yield/fed across bud chips planting method. Otherwise, the previous results were not found for conventional planting method, reflecting the remarkable effect of bud chips planting method on correlation coefficients corresponding to the seeding survival produced using that method. Brix recorded high and positive correlation with each of sucrose %, purity %, sugar recovery %, pol % and sugar yield/ fed across both planting methods.It is remarkable results that the correlation coefficients between each of sucrose %, purity %, sugar recovery % and pol % were equal or close to unity, reflecting the very strong genetic make-up of those traits.
