 Well, another thing we did was get a world collection, which you folks did in Metro. Another inheritor from the Metro program, we got a world collection of rice varieties. And from that, we began selecting certain ones. And what we were looking for was a short, stiff-draught, upright leaf variety compared to the tall, droopy leaf things that fell all over and you gave them a little fertilizer. And we found from Taiwan that we had this two varieties, Mijo, Wu-jen and Ijotsi, were short, stiff-draught, with a single recessive gene for shortness. We crossed those with the tall varieties that had disease resistance and were adapted to the tropical conditions of Asia and tropical and subtropical conditions. And the result was, in a very short time, we had some stiff-draught upright leaf varieties because of the fact that tallness is dominant over shortness. And so in the F1 generation, you cross a tall one and a short one, they're all tall. And then in the F2 generation, three quarters are tall and one quarter are short. And so we picked those short ones. And so in a matter of three years after we made that initial cross, we had one of you called IR8-288-3, which later became IR8. And we were able to get, under experimental conditions, we were able to get up to 10 metric tons per hectare when the average yield in the Philippines was 1.2 metric tons at the time we went in there. And that revolutionized, that started the revolution in rice. And of course we continued to make crosses and to get better and better varieties for disease and insect resistance to go along with the plant type and matter of grain quality from standpoint of appeal. And you had an order of priorities for each of these, you had to get over one hurdle at a time, right? Yes. Or the major emphasis was given. We were pretty lucky on that first cross, which Pete Jennings made the cross. Hank Mitchell selected the IR8 out of the other population. And Titi Chang, a Chinese geneticist, I brought the variety from Taiwan, told us about it, so we learned about that. And so they all played an important part in the development of this. From there on we went. And we got, as fast as we could, we got these varieties out to other countries. And they, of course, were able to multiply them and select them, and they took hold very fast. And as I mentioned yesterday, I think, in the conversation that 18 months after we introduced IR8 in the Philippines from 1960, 64, 65, 50% of the people there in Luzon with irrigation were growing, as charged, they dropped variety. And that's pretty fast. And then, of course, we went on to other ones that were much better than that. But in this regard, they say today, eerie people say, that there are 700 million people who are being fed today that could not have been fed, had this new kind of rise that responded to fertilizer. That would put the growth in the grain rather than all in the straw.
