抄録: An acute increase in human population has led to the serious problem, food crisis. To enhance the agricultural productivity, development of infertile lands, such as saline soil and arid area, was inevitable. It was a new challenge to establish the sustainable agricultural method suitable for these infertile lands without using the so-called high energy-high yield type modern technologies. Some of the results in Japan-China Joint Research from 1990 to 1999 on sustainable agricultural production in saline soil were summarized. A major approach to attain the goal was to select tolerant species to salinity. Many kinds of seeds were collected from all over the world and selection had been continued for 10 years. A few varieties of wheat, barley, rice, beans, pasture and fruit trees were selected as a highly salt-tolerant species. Selection of varieties was time-consuming and laborious process, however, it is now understood that it is superior than production of transgenic plants on the point that the former can select most adaptable varieties that are tolerant to many kinds of stresses often encountered in the actual fields. The mechanism of salt-tolerance was also described.
