During the PIP，promising varieties of crops，such as wheat，beans，rice，gaoliang，millet，and barley，were cultivated and then distributed among farmers.According to the Statement of Project made by Reisner in 1931，until then，28 improved strains and varieties of wheat，millet，gaoliang，corn，and cotton had been put into more fields and had already been distributed.26 This project made great achievements in terms of the improvement of seed varieties and the increase of food supply at a time when people suffered from serious food shortage.Planting improved varieties seemed to be a shortcut of solving the grain problem in China.27\n\t\t\t\tBesides，the standard methods of crop improvement were formulated in China for the first time，and then extended to the whole country.Meanwhile，the program cultivated a group of welltrained agricultural scientists and technicians with professional knowledge and creativity，who were able to carry on and expand the work after the Cornell professors had left.
