BREEDING AND ANTHER DERIVED LINES OF RICE (ORYZA SATIVA L.) FOR SALINE COASTAL AREAS OF BANGLADESH

Twenty seven anther culture lines (AC-lines) from rice (Oryza saliva L) were produced from salute tolerant F, progeny after crosses between salt tolerant IRRI-derived lines and Bangladesh Rice and advanced up to Double Haploid 3 (DH3) generation Similarly crossed material, which did not respond to anther culture. was also advanced up to F-7 The AC-lines were fully characterized for various salinity tolerance parameters at seedling and reduction division stages. The breeding lines were selected for tolerance again at F-4 and advanced on site in the coastal area DH3 plants were also evaluated for agronomic performance in normal soil The best performing breeding as well as AC-lines in terms of salinity tolerance and agronomic properties were planted in farmers fields in the Bore season, when salinity levels are the highest in the coastal zones of Satkhira One anther derived line AC-1 and three breeding lines, BR7076, BR7077 and BR7098 produced high yield under stress conditions, whereas AC-1, 13127076 and BR7077 showed moderate reduction in grain yield compared to non-saline conditions Considering both tolerance and yield performance in the saline area, AC-1 showed more stability compared to the breeding lines
