As a breakthrough in breeding, it led to unprecedented gains in national productivity and sugar recovery, setting new benchmarks for performance and reshaping the criteria for varietal selection across the country. Its rapid adoption across the major sugarcane-growing states in Northern India was a testament to its success and achievement. However, this success led to over-exploitation of the variety, with widespread cultivation beyond its recommended zones and without adherence to biosecurity protocols, resulting in extensive monoculture and associated risks. These factors, compounded by institutional inertia and lack of a robust, healthy seed programme, undermined the resilience of the sugar industry and disrupted its previously sustained pace of productivity and profitability. The breakdown of the variety due to red rot, possibly influenced by the Vertifolia Effect, led to a classic ‘boom and bust’ cycle, reminiscent of previous varietal collapses following monoculture practices. This article revisits the journey of Co 0238, not to assign any blame, but to learn valuable lessons for the future of a sustainable sugar industry. It highlights the importance of viewing varietal transitions as strategic shifts that bolster resilience, rather than mere replacements. By embracing genetic diversity, timely supply of pathogen-free seed material, a well-coordinated and well-resourced national clean seed propagation system, and science-driven decision-making, the sugar industry can mitigate similar crises and ensure long-term sustainability.</p></div>","PeriodicalId":781,"journal":{"name":"Sugar Tech","volume":"27 5","pages":"1670 - 1677"},"PeriodicalIF":2.0,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144920473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Single-factor experiments and orthogonal optimization of culture conditions were conducted for analysis. The results indicated that the optimal fermentation conditions for <i>C. militaris</i> polysaccharides (CMP) were 6% (6 mL/100 mL) corn steep liquor, a 7% (7 mL/100 mL) inoculation amount, and 0.10% inorganic salt (KH₂PO₄: MgSO₄ = 1:1). The fermentation yield of CMP was 1.185 g/L, which was 20.43% higher than that of the conventional group. Ultraviolet and FTIR spectroscopy analyses confirmed that CMP was a nucleic acid- and protein-free β-pyranose. Scanning electron microscopy (SEM) observations revealed that the CMP surface was rough, irregularly connected, and contains voids, exhibited a relatively compact polysaccharide structure. In vitro antioxidant assays demonstrated that CMP possessed significant antioxidant activity and could serve as a potential source of functional food. These results provide a novel approach to enhance the production of CMP using CSL as a medium, and explored promising biological activity and economic potential of <i>Cordyceps militaris</i> polysaccharides. </p></div>","PeriodicalId":781,"journal":{"name":"Sugar Tech","volume":"27 5","pages":"1659 - 1669"},"PeriodicalIF":2.0,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144920516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents a manually operated machine designed to produce compressed jaggery cubes from jaggery powder, specifically selected for its particle size (less than 0.300 mm) and moisture content (7.00%).

The results showed that sludge compaction and turbidity removal decreased by 5% and settling rate by 30% if the juice brix varied from 13 to 15°Bx. A mathematical regression model was used to correlate the settling rate with the juice brix with excellent goodness-of-fit. This mathematical model showed that the dependence of the settling rate on the juice brix was non-linear. The settling rate was most sensitive when the juice brix varied between 10 and 14°Bx, which means that small changes in brix in this range have a large effect on the clarification performance.

The incorporation of novel isomerase enzymes encoded through the <i>Sweet Sucrose Isomerase Gene III (SSGIII)</i> emerged as a promising strategy to augment sugar recovery percentage. This study meticulously engineered the <i>SSGIII</i>, optimized for expression in sugarcane, and subsequently introduced it into plant expression vectors under the influence of single and double promoter systems in conjunction with vacuole-targeted signal peptides at the 3′ end. The real-time PCR (RT-PCR) manifested the increased expression of <i>SSGIII</i> in sugarcane stalks relative to the leaves recommending a tissue-specific enhancement of sugar metabolism. The tested transgenic lines, SS-70, SS-55, SS-111, upheld very high level of sweetness in sugarcane. Transgenic line SS-220 transformed with triple gene constructs exhibited the maximum level of enhancement in sugar contents with a 27% improvement than13% over control line. This unprecedented augmentation was also seen to increase with maturity while reached optimum at the age of 18 months, underscoring the developmental dynamics influencing gene efficacy. The elite sugarcane line SS-220 displayed the highest Isomaltulose concentration (650 mM), substantiating the potential of triple gene constructs for maximal metabolic redirection. Furthermore, the Brix analysis corroborated these findings, exhibiting a surge in sugar content encompassing over 100% in transgenic lines relative to control plants. This investigation highlights the transformation potential of leveraging tailored genetic modifications, through the strategic deployment of <i>SSGIII</i> under diverse promoter systems, to significantly elevate sugar content in sugarcane.

Harvesting method combinations did not affect the productivity of dry leaves, tops, or stalks, nor the technological parameters. Average B and Fe contents were adequate, while Cu, Mn, and Zn were below recommended levels. The contents of Cu, Fe and Mn varied significantly between harvesting systems. While the harvesting systems over 32 years did not influence the productivity and technological parameters of the crop, the levels of micronutrient, except for B and Zn, and OC were affected by the different harvesting approaches.
