Classical breeding

Ebook "Tomato yellow leaf curl virus disease: Management, molecular biology, breeding for resistance" will awaken the interest of breeders, phytopathologists, environmentalists, extension services, plant virologists, entomologists and molecular biologists. It deals both with the epidemiological aspects of the disease and with integrated pest management in the field. It discusses the efforts aimed at breeding tomato plants resistant to the virus (using classical breeding, marker-assisted breeding and genetic engineering).

Cotton is an essential fiber producing crop in the world. It also supports additional industries by providing high quality oil and protein in the form of cottonseed cake. Currently, there is an urgent need to increase lint yield, fiber quality, and resistance to biotic and abiotic stresses due to rising pressure from a global population and possible supply shortages from the effects of erratic climate changes. Classic plant breeding and transgenic strategies need more genetic breakthroughs to support the increasing pressure for fiber quantity and quality.

"Evaluation of Lonicera caerulea L. genotypes based on morphological characteristics of fruits germplasm collection" is known that a polymorphic population consisting of a large number of genotypes adapts more rapidly to the environment conditions. The availability of a large gene pool predetermines the success of the introduction and further breeding of new cultivars with economically valuable features. Morphometrics is a classical tool for studying the amplitude of the variability of cultivated plants and evaluating the genotypic diversity of the artificial population.

Classical scrapie susceptibility in sheep has been linked to three polymorphisms at codon 136, 154, and 171 in the prion protein gene (PRNP) whereas atypical scrapie susceptibility is related to polymorphisms at codon 141. Many other variants over the length of the PRNP have been reported.

Excessive accumulation of salts is one of the most important factors affecting the production quality of plants. The difficulty to develop salt stress tolerant crops has prevented the security of the global food system. The classical crop breeding approach that uses random mutagenesis/recombination is time-consuming in the face of an ever-increasing human population and extreme weather pattern shifts.

Advances in genomics technologies are making it increasingly feasible to characterize breeding lines that carry traits of agronomic interest. Tobacco germplasm lines that carry loci designated VAM and va have been extensively investigated due to their association with potyvirus resistance (both VAM and va) and defects in leaf surface compounds originating from glandular trichomes (VAM only). Molecular studies and classical genetic analyses are consistent with the model that VAM and va represent deletion mutations in the same chromosomal region.

Heterosis has been exploited for decades in different animals and crops due to it resulting in dramatic increases in yield and adaptability. Hybridization is a classical breeding method that can effectively improve the genetic characteristics of organisms through heterosis.

The agricultural sector has already seen phases of raising crop productivity but this had huge impacts on the environment. This time, there is a need of „sustainability‟ to come into play. This is possible by increasing the base genetic variability and emphasizing on the Evolutionary Phase of plant breeding. This further requires the collaboration of classical or traditional breeding techniques with the modern biotechnological tools.

Fruits and vegetables are often referred to as “protective foods” because they are rich in minerals and vitamins. Fruit production is severely impacted by various biotic and abiotic stresses and during the past, efforts have been made by conventional breeding programs to mitigate these problems. However, classical breeding has had little success in improving fruit plants and is constrained due to long juvenile period, genetic erosion, genetic drag and reproductive barriers that limit the transfer of favourable genes from diverse genetic resources.

Classical plant breeding was extremely successful in generating high yielding crop varieties. Yet, in modern crops, the long domestication process has impoverished the genetic diversity available for breeding. This is limiting further improvements of elite germplasm by classical approaches.

Nematodes are the principal animal parasites of plants, causing annual crop losses of more than US$100 billion worldwide. Conventional control measures against nematode infection include toxic nematicide application to soil, crop rotation practices, and classical breeding approaches.
