| 摘 要： | 本试验在ＭＳ培养基中附加１．０％ＮａＣｌ胁迫条件下培养高粱幼叶组织，获得了２３２Ｂ衍一系Ｒ３代。经田间和实验室鉴定，Ｒ３形态性状，生育主籽粒品质都有明显变化。１．０％ＮａＣｌ水平上，Ｒ３－１１和Ｒ３－８盐害指数分别比原亲代Ｒ０下降２８．１％和１３．１％，耐盐等级分别提高２个和１个等级。

| Abstract: | Tissue of young sorghum leaves were cultured on MS media with 1 % NaCl and somaclonal lines of different generation, R1, R2 and R3 of 232B, were obtained. Results of field tests and laboratory examinations indicated that the morphological characters, maturity and seed characters of the R3 lines changed significantly from those of their progenitor 232B. When under 1% salt stress, the salt tolerant indexes of lines R3-11 and R3-8 decreased 28. 01% and 13.1% respectively as compared with that of R0; and their salt tolerant degree rose 2 and 1 degrees respectively. |
