In order to learn the evolution laws and genetic program of wheat cultivars,the wheat cultivars in Shandong province from 1950′s were analyzed.The results showed that the disease-resistance of wheat was promoted and plant height came to decreased;The contribution of primary characters of wheat to yield in evolution procession was grain number per spikematurity spikesweight of 1000 grainsplant height in 1950′s while the weight of 1000 grainsgrain number per spikematurity spikesplant height in present.Yield components tend to be reasonable and yield potential was improved.The heritability of plant height and length of main stem spike were higher,while that of yield potential was lower.
