In the first generation the seeds were all yellowish-white but in the second generation both bluish and yellowish- white seeds appeared. In 1854 Naudin was awarded a prize by the Paris Academy for his valuable work on plant hybridization.
He showed that the parental characters did not actually blend in the offspring of the first generation; he further showed that the characters reappeared separately in parental forms in the second generation of the cross.
He also made reciprocal crosses and proved the identity of the first generation. He almost hit upon the laws of heredity but failed to enunciate them because he did not count the number of progeny.
