This research was conducted to assess the agronomic performance of wheat advanced lines developed by Purdue University small grain program under Kabul agro-ecological conditions. Eleven wheat advanced lines from Purdue University and three local check varieties from Kabul were tested for three years under Kabul agro-ecological conditions. Genotypes differed significantly (P < 0.05) for grain yield and the yield components, and a fairly stable performance across years. Spike length and kernel weight were significantly correlated with grain yield, having R2 values of 0.54 and 0.53 respectively. Two Purdue lines: SNOWMASS and IN0762 outperformed the local checks, yielding 2.79 t/ha and 2.62 t/ha respectively. A genetic similarity analysis clustered the studied genotypes into three distinct groups, with some of the local varieties falling in the same category as the exotic lines. The study found exotic lines to be adapted to Kabul conditions, and can be utilized in local breeding programs.
