Abstract: With the growing salinity of our country, how to improve salt tolerance of plants, cultivated new varieties of salt tolerance and increase crop production under salt stress has been the subject of attention. In this paper, the excellent mutant plant of “Hua30” is chosen for screening salt tolerance of seed germination and then breeding to identify its agronomic traits in fields. The results show that salt tolerance of four test materials are improved, and the germination rate, coleoptile length and main root length of four materials are inhibited but the degree of inhibition is significantly less than “Hua30”. “Ha08-11” has the highest rate of panicle with good relative within four test materials and could be promoted the use of new straits of barley in Shanghai region.
