Final answer:
Georgii Karpechenko conducted hybridizations between plant species and discovered the creation of a hybrid plant called Triticale. He did this to explore the potential of creating new crop varieties with desirable traits.
Step-by-step explanation:
Georgii Karpechenko, a Russian botanist, conducted hybridizations between different plant species in order to produce new hybrids with unique characteristics. One of his most significant findings was the creation of a plant called Triticale, which is a hybrid of wheat and rye. Karpechenko's main motivation for conducting these hybridizations was to explore the possibilities of creating new crop varieties that would possess desirable traits from both parent species, such as increased yield or disease resistance.
