抄録

To analyze the growth and yield response to salinity of soybean genotypes with differences in salt tolerance at the vegetative stage, eleven genotypes which were classified into 4 groups, namely AGS313, G00209, G00028 and G00283 in the tolerant group, PK416, AGS399 and G00138 in the moderately tolerant group, BARI soybean 5 (BARI-S-5) and Shohag in the moderately susceptible group, and Bangladesh soybean 4 (BD-S-4) and G00046 in the susceptible group were grown in pots filled with soil at the Department of Agronomy of Bangabandhu Sheikh Mujibur Rahman Agricultural University in Bangladesh. The salt solutions (0, 50 and 100 mM NaCl) were applied from the appearance of the 1^st trifoliate leaf stage till maturity. Though the onset of flowering in most of the soybean genotypes was not affected by the NaCl salinity, except for three genotypes that flowered late, pod maturity in all the eleven genotypes was enhanced substantially. The relative grain yield (% value to the control treatment) of the genotypes displayed a positive correlation with the relative total dry weight, relative pod number plant, relative seed number per pod, and 100-seed weight. The relative reduction in the leaf dry weight, total dry weight, grain yield and yield-contributing characters due to salinity was lower in the genotypes of the tolerant group than in those of the susceptible group. The genotype AGS313 displayed the highest values of the relative leaf dry weight, root dry weight, total dry weight and grain yield at both 50 and 100 mM NaCl, followed by G00209. The highest relative grain yield of the genotype AGS313 was attributed mostly to the combined effect of the high value of the relative 100-grain weight and pod number per plant. Therefore, the high relative yield of AGS313 indicated its high genetic potential for the improvement of salinity tolerance in soybean.
