Mirza (HacA +/- zade) Gokgol (1897-1981) was a leading agro-ecological plant scientist, agronomist and breeder in Turkey. Gokgol carried out extensive breeding programmes extensively selecting from local plant genetic resources from across Turkey from 1925 till the 1950s. He collected and evaluated cultivars, landraces and wild relatives, predominantly of wheat, but also of barley, lentil and other crops in Turkey during 1929-1955. He published books on wheat and other cereals, potatoes, castor bean, sweet clover, poppy, and other crops. He was a hardworking pioneer utilizing wheat genetic resources for crop improvement. Since his ample work has hardly been accessible by the English-speaking scientific community today, we are providing an overview of his major work, mainly on wheat. The books he published can still be found in libraries, although with difficulties. However, his articles, leaflets etc., are hardly accessible. Some of them are: Turkish Wheats, vols. 1 and 2, Plant Breeding through Scientific Methods (1928, translation of a book by E. Baur), The Basics of Wheat Breeding (1954), and Agriculture and Breeding of Cool Season Cereals-Wheat, Rye, Barley, and Oats (1969). In addition to the summary of his books, we reviewed his views and discussions about the centres of origin and diversity, and compared with those of Vavilov.
