| Summary: | A set of International Potato Center (CIP)-bred
potato clones was evaluated for their salt tolerance and
productivity in replicated field trials in three coastal
districts of Bangladesh, namely, Chittagong, Patuakhali
and Satkhira. In each year of experimentation from 2011
to 2015, salinity levels increased progressively during the
season and varied with time and place. Evaluation and
selection were carried out using GGE biplot analysis and
mean yield across the test sites; and the best performing
clones were selected for the next year’s trial. Of the original
fifteen test clones, two (CIP 301029.18 and CIP 396311.1)
were selected for evaluation in the regional yield trial
with cvs. Diamant and Asterix as checks. In the regional
yield trial, across locations, CIP 301029.18 was the highest
(21.8 ton/ha) and CIP 396311.1 (21.3 ton/ha) was the 2nd
highest yielder such that CIP 301029.18 produced 64.0%
higher yield and CIP 396311.1 produced 32.4% higher yield
compare to their corresponding check varieties Diamant
and Asterix. Similar ranking was found under farmers’
field conditions. Finally, these 2 clones CIP 301029.18 & CIP 396311.1 were found promising for their good productivity
under saline conditions and CIP 396311.1 was released by
the National Seed Board in Bangladesh in 2016.
