To determine genetic and geographical diversity in indigenous wheat collections from central regions of Iran, 1091 collections from Isfahan, Chahar Mahal Bakhtiari, Fars, Kerman and Yazd were studied in 1990-91 in the Experimental Field, College of Agriculture, Karaj, Iran. Each entry was planted in a 3 m row. Rows were 5 m apart. After every 50 entries, a row of Karaj-1 was planted as check. Traits studied were: flowering time at 50% flowering, plant height in Cm,.biological yield in Kg, spike length in mm, and number of seeds per spike.
Statistical analyses were done for each trait. Regions and genotypes were grouped through cluster analysis. Analysis of variance showed that regions were significantly different for all rtaits under study. Cities of the regions were grouped into nine clusters. It was found that genetic diversity follows geographical diversity, closely. Significant correlations were found between yield and all other traits, except spike length.
