Abstract
An
experiment was conducted at the Sher-e-Bangla Agricultural University
during June through December 2014 to study the performance of local
and modern transplanted rainy season rice varieties under drought
stress condition. The experiment comprised 16 varieties; four modern
(BRRI dhan34, BRRI dhan33, BRRI dhan62 and BU dhan1) and twelve local
varieties (Kartik Shail, Doodh Kalam, Nakhuchi Mota, Kartik Balam,
Lal Mota, Kalo Khaia, Changshai, Basmati Shakkar Khanna, Dholi
Chikon, Ghashful Chikon, Moulata). Two experiments were set; one in
pot (stressed condition) in completely randomized design, while
another in a field following a randomized completely block design
under non-stressed condition. Stress condition was imposed providing
water in the pot only when soil of the pots dried and plants showed
wilting symptoms. Each treatment was replicated three times. In
stressed condition, at the time of harvest, longest panicles (28.533
cm) were found in Lal Mota and Basmati Shakkar Khanna, respectively;
highest number of total grains panicle-1 (163.33) and filled grains
panicle-1 (135.33) were recorded in BRRI Dhan 34. The longest panicle
(31.50 cm), highest number of total grains panicle-1 (300.00) and
filled grains panicle-1 (255.67) were recorded in Basmati Shakkar
Khanna; Local varieties especially Moulata could be recommended for
further trials in multi locations for T. Aman cultivation in stressed
region. Key words: Local rice, modern rice, T. Aman rice, panicle and
drought stress.
