Abstract
The present study was conducted to evaluate 50 wheat genotypes
for their productivity and stability under eight environmental conditions.
Wheat genotypes were sown at two planting dates under two nitrogen fertilization treatments during the winter seasons of 2018/2019 and 2019/202. The
analysis of variance showed that the mean squares of genotypes, sowing
dates, and nitrogen fertilization treatments were significant for the number of
spikes/plant, the number of kernels/spike, 1000-kernel weight, and grain
yield/plant. The results showed that sowing at the favorable date using 80 kg
N/fed increased all studied traits. This study revealed that line numbers 9 and
10 exhibited general adaptability across different environments; hence, these
lines are considered promising and could be exploited in breeding programs
for wheat improvement.
