“…The concentration of soluble sugar, proline and other soluble proteins influences the magnitude of impact of chilling injury to plant. This was confirmed by Wang et al (2021) who identified two to eight times higher concentration of soluble sugars and proteins in cold‐tolerant mutant line of banana. This showed that various proteins and transcription factors are involved in complex cellular alterations arisen due to cold stress and thereby regulate signal transduction and different pathways involved in tolerance mechanism.…”

“…From traditional selection scheme to marker‐assisted selection, mutation breeding, somaclonal selection and genetic engineering are being deployed in banana breeding programmes. Wang et al (2021) identified a mutant “ReFen 1” by mutagenizing the “FenJiao” with ethyl methanesulfonate. This mutant showed significantly higher cold tolerance than parent “FenJiao” due to increase in amount of soluble content of sugar and substantial raise in starch accumulation.…”

Global production of bananais adversely affected by abiotic stresses, namely, drought, salinity and low temperature which cause changes in morphology, anatomy, physiology and biochemical metabolism in plant. Different banana cultivars respond differently when grown in subtropical regions due to changes in temperature mainly at the time of flowering and fruiting. The subtropical regions persist cold in winter which become a major constraint for proper growth and development of banana. Only few cultivars are identified for cold tolerance. The cold tolerance is a complex phenomenon, involving numbers of interrelated metabolic pathways. With the onset of cold, growth decrease through alteration in the synthesis of metabolites which are regulated by expression of genes and their interactions. Recently, complete genome sequencing, mutation and transgenesis provided deep insight into the complex mechanism of cold tolerance in banana. In this review, efforts are made to compile the findings and to interpret the better application of technologies in understanding the cold tolerance which may assist in banana breeding.

“…After mutagenizing a plant, the first generation of seeds can be selected and selfed in successive rounds to create a large near-isogenic homozygous seed bank ( Till et al., 2003 ). Homozygote is difficult to achieve in obligate vegetative breeding species, such as bananas ( Wang X et al., 2021 ). However, homogeneous populations with fixed heterozygote and common features in all plants can be produced by clonal reproduction.…”

Ethyl methanesulfonate (EMS)-induced mutagenesis is a powerful tool to generate genetic resource for identifying untapped genes and characterizing the function of genes to understand the molecular basis of important agronomic traits. This review focuses on application of contemporary EMS mutagenesis in the field of plant development and abiotic stress tolerance research, with particular focuses on reviewing the mutation types, mutagenesis site, mutagen concentration, mutagenesis duration, the identification and characterization of mutations responsible for altered stress tolerance responses. The application of EMS mutation breeding combined with genetic engineering in the future plant breeding and fundamental research was also discussed. The collective information in this review will provide good insight on how EMS mutagenesis is efficiently applied to improve abiotic stress tolerance of crops with the utilization of Next-generation sequencing (NGS) for mutation identification.

“…In vitro technologies have also contributed to the development of methods for raising virus-free plants, rapid multiplication of elite clones, somatic embryogenesis, soma clonal variation, transgenic plants, and germplasm conservation. In the case of vegetatively propagated plants, multicellular meristems are often employed for undertaking in vitro mutagenesis [53,54]; however, occurrence of chimeras and phenotypic instability are limitations. Somatic embryogenesis, temporary immersion, and plant cell cultures have immense potential for in vitro propagation and genetic transformation in fruit trees such as mango, banana, pistachio, apple, papaya, coffee, and date palm.…”

Fruit species contribute to nutritional and health security by providing micronutrients, antioxidants, and bioactive phytoconstituents, and hence fruit-based products are becoming functional foods presently and for the future. Although conventional breeding methods have yielded improved varieties having fruit quality, aroma, antioxidants, yield, and nutritional traits, the threat of climate change and need for improvement in several other traits such as biotic and abiotic stress tolerance and higher nutritional quality has demanded complementary novel strategies. Biotechnological research in fruit crops has offered immense scope for large-scale multiplication of elite clones, in vitro, mutagenesis, and genetic transformation. Advanced molecular methods, such as genome-wide association studies (GWAS), QTLomics, genomic selection for the development of novel germplasm having functional traits for agronomic and nutritional quality, and enrichment of bioactive constituents through metabolic pathway engineering and development of novel products, are now paving the way for trait-based improvement for developing genetically superior varieties in fruit plant species for enhanced nutritional quality and agronomic performance. In this article, we highlight the applications of in vitro and molecular breeding approaches for use in fruit breeding.
