ABSTRACT
An experiment was completed to examine the performance of high yield and heat tolerant wheat types under rising temperatures in hill districts of Bandarban, Rangamati Khagrachari (South Asia). During the Rabi season (November to March each year), the trial was done at 3 hill regions (districts) in Farmers field, Bangladesh throughout two crop seasons (2020-21 and 2021-22) at various locations in one upazilla in each of the 3 (three) hill region (districts). We use freshly announced high-yield wheat varieties for optimal sowing and heat tolerance as an adaptation strategy in hills suffering from terminal heat stress. BARI Gom 30, BARI Gom 32, BARI Gom 33, WMRI Gom 01, and WMRI Gom 02 were the five high-yielding heat tolerant wheat types. BARI Gom 33 (3.16 t/ha) has produced the highest crop output, followed by BARI Gom 30 (3.09 t/ha). WMRI Gom 02 (3.00 t/ha), BARI Gom 32 (2.97 t/ha) and the lowest performance was WMRI Gom 01(2.87 t/ha) in the last years. The difference in wheat crop output and biological yield was considerable, but the rest of the characteristics were unimportant. BARI Gom 33 was the yielded and adapted variety of the greatest likened to the others. WMRI Gom 01 had an insignificant benefit-cost ratio (BCR) of 1.06, whereas BARI Gom 33 had the maximum BCR of 1.22 in alliance with the five types tested, BARI Gom 33 was the high yielding and most adaptable.
