The large differences in productivity which exist between strains of cashmere goats are summarised in this paper, and approaches for choosing appropriate genotypes are discussed. Evidence is presented that there is little useful heterosis for fibre production traits, however heritabilities for these traits are consistently high, with most estimates being in excess of 0.5 for cashmere weight and fibre diameter, the two most important traits. These two traits are unfavourably correlated however. The impact of these genetic parameters on the genetic improvement of cashmere goats is considered.
