SCREENING OF JUTE MUTANTS FOR SALINITY TOLERANCE (Pages : 6 - 11)

A pot culture experiment was conducted at the pot yard of Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh during the period from February to May 2007 to screen jute mutants at different levels of salinity. The experiment was laid out in complete randomized design with three replications. In germination test, 20 jute genotypes were treated with 8, 6 dSm-1 and control where no salt was applied. Among these genotypes, only five were germinated at 6 dSm-1 salinity level. These five selected jute mutants viz. 0-9897 400 Gy P-26(1), 0-9897 500 Gy P- 58(2), 0-9897 500 Gy P-65(3), 0-9897 900 Gy P-72(1), 0-9897 900 Gy P-86(3) were then treated with control, 4, 6 dSm-1 salinity levels for growth and yield studies. The results revealed that plant height both at 85 DAS and maturity stage, number of leaves, leaf area, dry weight of roots, stem and leaves, total dry matter plant -1 at 85 DAS, base diameter, fibre and stick yields at maturity were gradually decreased with the increase in salinity levels. The highest plant height was recorded in 0-9897 900 Gy P-86(3) and 0-9897 500 Gy P-65(3). The mutant 0-9897 400 Gy P-26(1) produced the maximum number of leaves, dry weight of stem, leaves, total dry matter, fibre yield and stick yields. The maximum leaf areas, dry weight of roots were produced by 0-9897 500 Gy P-65(3). Under the inducing salinity condition 0-9897 400 Gy P-26(1), 0-9897 500 Gy P-65(3) and 0-9897 900 Gy P-86(3) performed better than other mutants with respect of morphological and yield attributing characters.
