Hybrid rice in Yuan Longping is a hybrid of indica rice with poor taste, and the taste is even worse. Few people eat it now, and it is usually used as animal feed. In the past, when the older generation was short of materials, they could survive with enough food. Hybrid rice has largely solved the problem of people's food and clothing. 1976, Yuan Longping's hybrid rice was widely popularized in China. By 1988, rice in Yuan Longping has been planted in half of the country's paddy fields. However, with the improvement of living conditions, people choose rice with better taste to eat. At present, the planting area of hybrid rice in Yuan Longping has been reduced to no more than 8.542% in China, and it has withdrawn from the main rice varieties. Therefore, it is said in books and the media that Yuan Lao's varieties are generally beyond our purchase.

Because the hybrid rice in Yuan Longping is a rice variety that pursues higher yield, shorter growth cycle and stronger soil adaptability, it gives up the index of taste. In three or even four seasons of the year, from 700 kg, 800 kg and 900 kg in the past, the yield per mu in two seasons broke the world record again, and the yield increased to the extreme. When the extreme weather for years makes the grain yield decrease or even war, hybrid rice, as a strategic material, can be produced quickly to fill people's stomachs and solve people's food problems.

The contribution of hybrid rice is not only in China, but also of great help to the whole world. Although China is not short of food now, the food problem in some African countries is still serious. Over the years, Academician Yuan Longping has devoted himself to pushing hybrid rice technology to underdeveloped countries, helping those countries get out of the basic food dilemma, and has successively trained tens of thousands of professionals to take root in these countries, making great contributions to eliminating world hunger.
