Salinity is a major abiotic stress limiting crop production in 20% of global cultivable land which also include 1.05 million ha (12.35%) in the coastal areas of Bangladesh (FAO, 2017; SRDI, 2016). The saline areas in Bangladesh remain mostly fallow during November to June due to soil salinity (2.0 to >16.0 dS/m) and scarcity of suitable irrigation water. Management of the saline soil for economic crop production is costly and sometimes impossible. Therefore, development of low water demanding crop variety with tolerance to salinity might be the best alternative to ensure food security of 160 million people of Bangladesh. As wheat needs only 2--3 irrigations to complete its life cycle, seeds of a salt tolerant segregating mutant population, L-880 of wheat were introduced from NIAB, Pakistan, screened and evaluated under saline field conditions during 2011--12 to 2014--15 growing seasons along with BARI Gom-25 (which can tolerate 8 dS/m salinity). Final yield trials were conducted at four locations each in saline and non-saline areas. The soil salinity of saline affected locations was recorded from 15 November 2015 to 20 February 2016 which showed gradual increase of salinity from 15 November and reached the highest (12.52 dS/m) at Khulna on 20 February (Fig.1). The mutant L-880-43 produced significantly higher grain yield than the check variety even under the highest salinity and in non saline soils as well (Fig.2). Considering all, National Seed Board of Bangladesh released it as Binagom-1 in 2016 for commercial cultivation in the saline and non-saline areas of Bangladeh. [ABSTRACT FROM AUTHOR] |
