Principles of Genetics and Breeding (1+1)

2.1.1 Mendal’s law of inheritance

• Gregor Johann Mendel(1822-1884) initiated a series of hybridization experiments in 1857 by experimental crossing of pea varieties, Pisum sativum.
• After 8 years of research in 1865, he delivered first lecture on pea experiments to Brunn Natural Science Society.
• In1866, his paper "Experiments onplant hybridization" was published in volume IV of Proceeding of Natural Science Society. Based on his hybridization experiments, Mendel proposed some basic genetic principles, rules of inheritance. But his remarkable piece of work was unattended and not appreciated up to 1900.
• In 1900 three botanists simultaneously, CarlCorrens (Germany), Eric Von Tshermak (Austria) and HugoDevries (Holland)reported the rules governing the transmission of traits from parents to offspring independently, which gave the credit for the discovery to Mendel.
• After death Mendel received recognition and honour as “Father of Genetics”. Mendel's original paper was republished in Flora, (1901). This marked the beginning of modern genetic research. Mendel's experimentation is now recognized as a classic example of carefully planned and executed scientific research and his paper as an excellent illustration of scientific genius.
