Webc) Hybrid Varieties: In most self-pollinated crops, F 1 is more vigorous and higher yielding than the parents. F 1 is used directly as a variety. Types of Hybridization: On the basis of taxonomic relationships of the two parents, hybridization is of two types – Intervarietal & Distant hybridization. 1) Intervarietal Hybridization: WebThe first artificial interspecific plant hybrid was produced by Thomas Fairchild in 1717. It is commonly known as ‘Fairchild Mule’. Hybridization was first of all practically utilized in crop improvement by German botanist Joseph Koerauter in 1760. Mendel onward, the hybridization had become the key method of crop improvement.
