| Abstract: | This test involved the selection of sixteen wheat varieties which had been planted in three ecological areas of shaanxi province for many years. A classification function and canonical discriminant analyst were the two meathods of discriminant analyst of the ecotype. The result shows that it is feasible to use the following five yield factors: number of kernels per spike, number of spikelets per spike, stem/grain, 1000-kernel weight and number of ears per plant in classing ecotype. The discriminant ability of kernels/per spike, spikelets/per spike and stem/grain are the best factors among them, and the discrirninant result accords with their ecological areas of origion. |
