| description | Corchorus olitorius L. jute is a natural fiber crop that is very susceptible to salinity stress. Salinity in soil is a serious threat to tossa jute cultivation in salt-prone regions of Bangladesh. Development of salinity stress tolerant tossa jute variety is a crying need in Bangladesh. Hence, 22 tossa jute genotypes were investigated in an augmented design against 7.86–7.93 dSm−1 salinity stress at coastal regions of Bangladesh during 2017-2019. Salt-tolerant jute genotypes were phenotypically screened out based on survivability, vegetative growth, plant height, base diameter, and fiber yield capacity. Among all genotypes, Acc. 4160 and Acc. 2311 showed good fiber yield (18.0 and 13.8 g plant-1, respectively) with the lowest mortality rate (5.67 and 8.0%, respectively). Acc. 1381, Acc. 2307, Acc. 1334, Acc. 1381 and the pre-released varieties, namely O-9897, BJRI Tossa Pat 5, JRO-524 (Green) were also found good for the aforesaid traits. Among the studied characters, high heritability in a broad sense, genetic advance (%) of mean and significant associations were found which contribute to fiber yield significantly. According to the Clustering and principal component analyses, the relatively salt-tolerant genotypes of cluster II (Acc. 4160, Acc. 2311, Acc. 2307, JRO-524 (Green), Acc. 4327, BJRI Tossa Pat 5, Acc. 1334 & Acc. 1381) could be used as breeding materials and sources of salt-tolerant genes to develop salt-tolerant tossa jute variety. |
