“…In general, the radicles of the studied Plantago species were more affected by an increase in Zn, Cu, and Fe doses than the cotyledons. Iron toxicity can result in the presence of leaf chlorosis, darkening of roots (74), and reduction of the total water content (75), leading to reduced plant growth (76). The results regarding radicle and cotyledon tolerance indices indicated that the lowest concentrations of these metals induced an increase in tolerance, whereas high concentrations decreased this parameter.…”

Heavy metal contamination is an increasingly pressing global ecological concern adversely affecting plant growth. Phytoremediation is an eco-friendly and low-cost approach to help solve this problem by using plants to remove metals. This study aimed to evaluate the phytoremediation potential of four Plantago species, exposing them to different concentrations (0, 150, 300, 600 and 900 ppm) of zinc, copper, and iron during germination and early seedling growth. These are generally the phases of the plant life cycle most sensitive to stress. The germination percentage (GP), mean germination time (MGT), radicle, hypocotyl and cotyledons length, biomass, water content and tolerance index (TI) were recorded under controlled conditions. The results indicated that metal-induced stress significantly reduced GP, increased MGT, and inhibited seedling growth with increased metal concentration. The relative toxicity of the tested metals could be ranked as Fe > Cu > Zn. Regarding the Plantago species, P. tunetana and P. lanceolata could be considered highly tolerant, P. albicans moderately tolerant, and P. afra low-tolerant to metal toxicity during germination. Therefore, P. tunetana and P. lanceolata present an excellent potential for phytoremediation of metal-contaminated zones.

“…When two desired traits are positively correlated, the plant breeder can focus on improving both traits at once, however negative association will prevent the characters from expressing themselves similarly [16]. Comparable results were documented by [32][33] for days to 50% heading, days to maturity, plant height, number of productive tillers per plant, ear length, ear weight, number of grains per ear, harvest index, chlorophyll index, test weight and biological yield per plant [30][31][32][33][34][35].…”

The experimental material of present study comprised of 127 treatments and 4 check varieties in augmented design conducted during rabi season (2022) in research field of Genetics and Plant Breeding, Lovely Professional University, Phagwara, India. Observations were recorded for days to 50% heading, days to maturity, plant height, number of productive tillers per plant, ear length, number of spikelets per ear, ear weight, number of grains per ear, test weight, biological yield per plant, harvest index, chlorophyll content and grain yield per plant. Analysis of variance disclosed that treatments and check varieties are highly significant for all the characters. Phenotypic coefficient of variation noted higher magnitude than genotypic coefficient of variation for all the traits. Heritability combined with genetic advance as percent of mean is noted high for grain yield per plant, biological yield per plant, number of productive tillers per plant, ear weight, harvest index, test weight, ear length, number of spikelets per ear, number of grains per ear and plant height. The correlation coefficient assessed positive and highly significant for biological yield per plant, number of productive tillers per plant, harvest index, ear weight, plant height, test weight and ear length. Grain yield per plant recorded positive significant association with biological yield per plant (0.7816), number of productive tillers per plant (0.7051), harvest index (0.527), ear weight (0.4076), plant height (0.3632), test weight (0.3222), and ear length (0.2439), whereas negatively significantly associated with days to 50% heading (-0.4019) and days to maturity (-0.4019). The findings from path analysis unveiled that the maximum direct effect was noted for biological yield per plant, harvest index, number of spikelets per ear, number of productive tillers per plant, ear weight, days to 50% heading, test weight and days to maturity. Out of thirteen traits, eight traits exhibited direct positive effect on grain yield such as biological yield per plant (0.8282), harvest index (0.6061), number of spikelets per ear (0.107), number of productive tillers per plant (0.0191), ear weight (0.0138), days to 50% heading (0.011), test weight (0.0088), and days to maturity (0.0001).

Yellow mosaic virus (YMV) is a destructive viral pathogen that affects green gram (Vigna radiata) crops, leading to significant yield losses and economic repercussions. This review paper provides a comprehensive analysis of the impacts of YMV on green gram cultivation, explores the current management strategies employed to combat the disease, and discusses future perspectives for effective YMV control and prevention. YMV is primarily transmitted through whiteflies and infects green gram plants at various stages of growth, causing severe symptoms such as leaf yellowing, stunted growth, and mosaic patterns. These symptoms ultimately lead to reduced crop yield and quality. The virus poses a major threat to green gram production globally, demanding urgent attention and effective management practices. Various management approaches have been employed to mitigate the impact of YMV. Cultural practices, including proper field sanitation, weed control, and crop rotation, play a vital role in disease management. Insecticide application, use of yellow sticky traps, and whitefly population monitoring are important components of integrated pest management strategies aimed at reducing virus transmission. Additionally, the development and deployment of resistant cultivars through conventional breeding and biotechnological approaches have shown promise in minimizing YMV infection and its associated losses. Despite these efforts, YMV continues to pose significant challenges to green gram production, necessitating further research and innovative approaches. Future perspectives for YMV management involve the integration of advanced technologies such as molecular diagnostics, genome editing, and RNA interference to enhance disease resistance in green gram varieties. Additionally, promoting awareness among farmers about YMV symptoms, preventive measures, and adoption of integrated disease management strategies will contribute to sustainable green gram production. In conclusion, YMV represents a major threat to green gram cultivation, affecting crop productivity and economic sustainability. This review emphasizes the need for concerted efforts to develop comprehensive YMV management strategies. By combining conventional and modern techniques, effective disease control measures can be implemented to mitigate the impact of YMV and secure the future of green gram production.
