Abstract Mungbean seeds, despite being protected inside the pod, are susceptible to pre-harvest sprouting (PHS) following rainfall due to lack of fresh seed dormancy (FSD), which deteriorates the quality of the seed/grain produced. Therefore, development of mungbean cultivars with short (10–15 days) period of FSD has become important to curtail losses incurred by PHS. In this study, we investigated variations in PHS, fresh seed germination (FSG) and activity of α-amylase enzyme in diverse… 
Genetic Variability and Correlation Studies for Pre-harvest Sprouting Tolerance and Associated Traits in Soybean [Glycine max L. Merrill.]
High estimates of genotypic (GCV) and phenotypic coefficients of variation (PCV) were recorded for the percentage of pods ruptured by sprouting seed (PPR) indicating the presence of wider variability over which selection can be effective and a significant negative correlation of PPR with pod wall thickness, number of pods per plant, and number of clusters per plant.
Biotic and Abiotic Constraints in Mungbean Production—Progress in Genetic Improvement
Mungbean [Vigna radiata (L.) R. Wilczek var. radiata] is an important food and cash legume crop in Asia. Development of short duration varieties has paved the way for the expansion of mungbean into
Effect of elevated carbon-dioxide on plant growth, physiology, yield and seed quality of chickpea (Cicer arietinum L.) in Indo-Gangetic plains.
The experimental findings depict that e[CO2] upto 600 ppm could add to the growth and productivity of chickpea in a sub-tropical climate with an implication on its nutritional quality of the produce.
A Class II KNOX Gene, KNAT7-1, Regulates Physical Seed Dormancy in Mungbean [Vigna radiata (L.) Wilczek]
Seed dormancy in wild mungbean (Vigna radiata var. sublobata) may be useful for the breeding of cultivated mungbean (var. radiata) with pre-harvest sprouting resistance. Previous studies have
Breeding Progress and Future Challenges: Abiotic Stresses
The strategy of reducing exposure to risk was very successful in transforming mungbean rather than identifying and breeding inherent resilience, and future research efforts must combine known sources of genetic variation with the investigation into the biochemical and physiological processes in order to understand and breed for tolerance to abiotic stress in mung bean.
Implications of rising atmospheric carbon dioxide concentration on seed quality
This review discusses about the possible implications of e[CO2] on quality attributes of seed affecting its planting value with much emphasis on seed weight, germination, vigour and its biochemical constituents.

For over a century, there has been a virtually unbroken trend in favour of increasingly intensive use of industrially synthesized nitrate fertilizer and against the traditional inclusion of legumes


Evaluation of mungbean (Vigna radiata) germplasm for pre-harvest sprouting tolerance
The character associations and direct and indirect effects revealed in the study give a preliminary idea about various plant, pod and seed traits playing role in the governance of pre-harvest sprouting in mungbean.
Evaluation of urdbean (Vigna mungo) germplasm for pre-harvest sprouting tolerance
The information on the performance of some popular urdbean cultivars with respect to PHS tolerance has been generated and some genotypes with relatively low PHS have been identified and comprehensive field evaluation is required before these genotypes can be used in breeding programmes.
Variation in seed dormancy and α-amylase activity in Indian rice (Oryza sativa) accessions
The α-amylase activity was low in dormant genotype and high in non-dormant genotypes and proved to be an efficient marker of the seeds dormancy level and can be exploited for development of rice variety with desired period of dormancy.
Breeding chickpea (Cicer arietinum [Fabaceae]) for better seed quality inadvertently increased susceptibility to adzuki bean beetle (Callosobruchus chinensis [Coleoptera: Bruchidae])
Genetic progress was achieved both in grain yield and seed size, but breeding efforts for these traits had also inadvertently increased seed susceptibility to C. chinensis, which resulted in higher infestation levels and seed damage.
Basic materials for mining new genes and developing new molecular makers to improve the tolerance of PHS in wheat as well as increase wheat production are provided.
Phenolics in the seed coat of wild soybean (Glycine soja) and their significance for seed hardness and seed germination.
Epicatechin is suggested to be functionally related to coat-imposed hardseededness in G. soja.
Effect of field weathering on the viability and vigor of soybean seed.
The wide range in seed vigor observed shortly after harvest maturity emphasizes the importance of timely harvest of seed fields and evaluation of seed viability and vigor soon after harvest.
