Breeding for Enhanced Root Traits to Improve Soil Carbon Sequestration | Chapter 10 | Agricultural Sciences: Techniques and Innovations Vol. 5

 

One of the most serious issues that the world is facing today is global warming. The increase of CO2 is one of the major causes of global warming. Efforts have been made to reduce the emission of carbon and also to discover ways to sequester atmospheric CO2. Soil carbon sequestration is one of the vital mechanisms that can reduce the effect of rising temperatures of the earth by absorbing atmospheric carbon. The root architecture of crop plants, when modified through breeding techniques for carbon sequestration, plays a role in reducing global warming. This chapter focuses on the various root characteristics that can contribute to soil carbon storage for a longer period of time. For instance, perenniality of crops influences a longer and more stable root system, which can serve for long-term carbon storage. The conventional breeding techniques have some disadvantages when it comes to breeding for root traits for carbon sequestration. Here, various new breeding approaches such as phenotyping, molecular breeding, genomic prediction, QTL, GWAS, metagenomics, etc. have been discussed in brief that can be used for breeding of crop varieties with enhanced root traits for soil carbon storage. Also, the various constraints related to it and the future prospects are discussed here.

Biotechnological Approaches for Genetic Improvement of Crops | Chapter 7 | Cutting Edge Research in Biology Vol. 7

 Biotechnological approaches are being secondhand widely in modern plant breeding for historical improvement of crops for mean traits and yield. The conventional training methods are mainly based on hybridization and collection of advance breeding lines. Advance biotechnological plans are rapidly being employed for realizing improved types in less span of time with seductive traits. These patterns include plant tissue idea, molecular rearing, and transgenic methods. Plant tissue civilization is helpful in assimilating somaclonal variants, embryo rescue, and for bulk propagation of plants through micropropagation, while microscopic breeding is being applied for gravestone assisted excerpt, varietal characterization, prominence and background excerpt and transgenics approaches are being used to transfer gene from different training in genome of crop plants. High throughput genotyping, next generation sequencing and genome refining are some of the recent biotechnological finishes being applied for favorable crop improvement programme. Current book chapter fixated on overview of few of the important biotechnological tools being used for crop improvement.

Biotechnological Interventions to Combat against Charcoal Rot and Rhizoctonia Root Rot Diseases of Soybean [Glycine max (L.) Merrill] | Chapter 01 | Current Topics in Agricultural Sciences Vol. 6

 Soybean is a key legume in the world's oilseed production system. Several biotic and abiotic stressors, including drought, have impacted soybean yield. Among the several biotic pressures, Charcoal rot and Rhizoctonia root rot are the most common diseases that cause significant damage to soybean production, and no significant work has been done to effectively address these issues. Biotic stressors can be managed utilising an integrated management approach that includes cultural methods such as crop rotation, tillage, and irrigation, as well as chemical control such as seed treatments to reduce damage caused by a fungal infection in soybeans. The goal of this work was to profile soybean genotypes for yield and accrediting features, as well as to validate gene-based SSR molecular markers against the diseases of charcoal rot and Rhizoctonia root rots. Genotypes JS335, JS20-69, JS97-52, KDS980, and KDS992 were found to be the most divergent and promising genotypes based on various traits and may be used as parents in future hybridization programmes to breed tolerance/ resistance to Rhizoctonia root rot and charcoal rot using conventional and/or molecular breeding approaches.
