“…Similarly, female lines 6 and 9 which showed varied and negative GCA for ASI and other parents that exhibited varied but negative GCA for PA, SGA and EA could serve as a source of germplasm from which low N tolerance genes which could be transferred to their progenies when used in hybrid combinations as well as for population improvement. These results corroborate the findings by ( He et al., 2018 ; Ogunniyan et al., 2019 ).…”

“…The substantial and varied of GCA for GY and secondary characters associated with GY sub-optimal N condition will guide plant breeders in the selection of superior lines to be used as female or male in generation of hybrids for genetic gain to be realised. The nonappearance of varied GCA for male and female sets under low and optima fertilizer applications for ASI, EPP, PH, EH, RL and SL indicates that such traits may not be key for yield improvement sub-optimal N environments, which does not agree with the findings reported by (Mafouasson et al, 2017;Zhang et al, 2018;Ogunniyan et al, 2019;Shimelis et al, 2019). The disparities in the two studies could be attributed to the sources of genetic materials used in this study as well as the conditions at which the other studies were conducted.…”

“…These lines will be valuable for the forming of high yielding hybrids targeting low N conditions ( Pswarayi and Vivek 2007 ; Weber et al., 2012 ; Kamutando et al., 2018 ). This also implied that such inbred lines have the capacity to transfer the characteristics to their F 1 progeny when used as parents in crosses ( Ogunniyan et al., 2019 ; Sun et al., 2019 ). Female line 15 and male lines 15 and 30 which displayed varied GCA effects for GY sub-optimal N application signified that; these parents possess highly heritable genes for GY which could be passed toto their F 1 progenies under marginal soil environments.…”

“…Significant effects of cultivars × crop cycles on the characters were indicative of the consequences of environment and difference in ratoonability of the cultivars. A significant effect of crop cycles for all the yield characters has been reported by Ogunniyan et al, 2020. On the other hand, non- significant variation for CCS% and CCS yield across crop cycles showed that sucrose accumulation in the cultivars did not vary over years. The results were concordant with that of Jamoza (2013) and Ogunniyan et al (2020) who reported that significant genotype × environment interactions existed for cane yields but not for sucrose accumulation.…”

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.

“…Palachai et al (2019) andOgunniyan et al (2020) show a positive correlation between sugarcane productivity, the number of stems, and stem weight. The crossed clones produced an average sugarcane yield of 9.79%, which was 8.10% lower than the female parent (10.65%).…”

Indonesia’s sugar productivity is low and requires improvement. Producing new superior sugar varieties may increase sugar productivity. In 2019, a polycross between female SIL 04 and male 6535, PS 881, and Bululawang made 11 potential clones. Therefore, it is necessary to determine each clone's characteristics. This research aimed to determine superior clones that generate higher crystal production than the female parents. The research location was the Agricultural Technology Research and Assessment Installation (Instalasi Penelitian dan Pengkajian Teknologi Pertanian - IP2TP) Karangploso from December 2020 until November 2021. The clones and female parents (SIL 04) were arranged in a Randomized Block Design using 2 replications. The research result showed that 9 clones (MLG 19/P6/1, MLG 19/P6/4, MLG 19/P6/5, MLG 19/P6/6, MLG 19/P6/8, MLG 19/P6/9, MLG 19/P6/11, MLG 19/P6/13 and MLG 19/P6/16) produced more crystals (7.07-12.95 t/ha) than the female parents (5.82 t/ha). To sum up, increasing sugarcane productivity improves crystal yields.
