The salinity susceptible CoC-671 and salinity tolerant sugarcane genotype CoM-265 were evaluated for Peroxidase (POX), Esterase (EST) and Alcohol Dehydrogenase (ADH) isozymes and soluble protein profiling by SDS and native-PAGE at salinity levels 0.41 dSm, 2.31 dSm, 4.21 dSm, and 8.01 dSm maintained by NaCl solution. The plant height, number of leaves and seedling diameter got reduced in salinity susceptible sugarcane genotype CoC-671 as well as salinity tolerant sugarcane genotype CoM-265 with increase in salinity levels. However, reduction in plant height, number of leaves and seedling diameter was less in salinity tolerant sugarcane genotype CoM-265 as compared to salinity susceptible sugarcane genotype CoC-671. The POX isozyme profiling revealed that salinity susceptible CoC-671 and salinity tolerant sugarcane genotype CoM-265 had variation in soluble protein band intensity at different salinity levels with relative mobility (Rm) 0.137. The present study could be useful for genetic variability analysis in sugarcane genotypes differing in salinity stress tolerance capability.

Sugarcane (Saccharum officinarum L.) is an economically important long-duration crop which is currently facing concurrent heat waves and soil salinity. The present study evaluates an inducible salt-tolerant sugarcane mutant M4209, developed via radiation-induced mutagenesis of elite check variety Co 86032, under heat (42/30°C; day/night), NaCl (200 mM) or heat + NaCl (HS)-stress conditions.

Sugarcane, which provides 80% of global table sugar and 40% of biofuel, presents unique breeding challenges due to its highly polyploid, heterozygous, and frequently aneuploid genome. Significant progress has been made in developing genetic resources, including the recently completed reference genome of the sugarcane cultivar R570 and pan-genomic resources from sorghum, a closely related diploid species. Biotechnological approaches including RNA interference (RNAi), overexpression of transgenes, and gene editing technologies offer promising avenues for accelerating sugarcane improvement.

Background: The transition from vegetative to floral development is a critical process regulated by a variety of complex internal and external factors. This study aims to characterize the Flowering Locus D (FLD) gene in relation to the floral induction pathway and examine its expression profiles under different photoperiodic conditions in Indian bean (Lablab purpureus (L.) Sweet).

Genotype selection for dry matter yield (DMY) in perennial forage species is based on repeated measurements over time, referred to as longitudinal data. These datasets capture temporal trends and variability, which are critical for identifying genotypes with desirable performance across seasons. In this study, we have presented a random regression model (RRM) approach for selecting genotypes based on longitudinal DMY data generated from 10 breeding trials and three perennial species, alfalfa (Medicago sativa L.
