| dc.description.abstract | An experiment was conducted at the experimental field of the Department of Genetics and
Plant Breeding, Hajee Mohammad Danesh Science and Technology University, Dinajpur,
Bangladesh during the period from November, 2016 to April, 2017 with eleven wheat
genotypes collected from Wheat Research Centre (WRC), BARI, Dinajpur. The genotypes
were namely- BARI GOM 22, BARI GOM 23, BARI GOM 24, BARI GOM 25, BARI
GOM 26, BARI GOM 27, BARI GOM 28, BARI GOM 29, BARI GOM 30, BAW 1194
and BAW 1200. Data were recorded on the following crop characters; no. of tillers/plant,
plant height, , spike length, no. of spikelet per spike, no. of grains/spike, twenty grain
weight, plot yield. The wheat genotypes were evaluated in randomized completely blocked
design with three replications to study genotype × environment interaction under drought
stress and to determine stable genotypes under drought stress condition. Different stability
models to estimate the stability of genotypes, Eberhart and Russell ‟sjoint regression model,
AMMI model, AMMI Stability Value (ASV), Yield Stability Index (YSI), GGE Bi-plot and
Shukla stability analysis were used in this experiment. All stability analysis revealed that
BARI GOM 23 and BARI GOM 24 were more stable and desirable genotypes for drought
stress condition in wheat. These two genotypes also showed maximum plot yield, yield per
plant, number of spikelet per spike, spike length, plant height and also required
comparatively less days to maturity. The study selected two genotypes, BARI GOM 23 and
BARI GOM 24 were the most stable and desirable genotypes under drought stress
condition with reasonable good yield among the all. | en_US |
