Differences between conventional and modern plant breeding methods.
Conventional plant breeding | Modern plant breeding |
---|---|
∙ The breeding method is based more on phenotype which creates unreliability in determining pure line of genes. | ∙ It is genotype based method of breeding which is more accurate in determining the pure gene line. |
∙ It is more time consuming to release a new variety. | ∙ It is comparatively less time consuming to release a new variety. |
∙ Variability in conventional breeding is created through hybridization. | ∙ Newly used technologies like Genomic selection, enviromics and High Throughput Phenotyping (HTP) are practiced to improve genetic gain of cultivars. |
∙ Generally, dominant genes are only selected. The selection of recessive alleles needs to undergo a long procedure. | ∙ The recessive alleles can be selected through the use of markers and identification of specific sites of gene which is quite shorter procedure than of the conventional. |
∙ It is less effective since it depends more on skills, arts and subjective analysis of breeder. This makes the result less reliable. | ∙ Modern Plant Breeding is more effective and trusted since it is based on scientific research and findings. |
∙ Conventional plant breeding demands less technical skills and scientific knowledge of genetics | ∙ In the same place, modern plant breeders are required with more technical skills and genetic science knowledge. |
∙ It is less expensive as it can be carried with local techniques and tools. | ∙ It is highly expensive as it requires high tech machineries and methodologies. |
