Abstract:
The color of flower,quantity of petals and sepals,corolla diameter,blooming date and flowering period of about 190 progenies of total 9 families were investigated.The results showed that the color of flower was controlled by 2 allelic genes.The genotypes of pink,red and white flowered phenotype of peach were R_W_,rrW_ and _ww respectively.Multiple-flower were controlled by a recessive gene.Inheritance traits of simple-flower and double-flower were not simple qualitative inheritance traits.Corolla diameter,blooming date and flowering period were quantitative inheritance traits,their inheritability were 0.76,0.73 and 0.95 respectively.There were some correlation between quantity of petals and sepals(r=0.882),quantity of petals and blooming date(r=0.576),quantity of petals and corolla diameter(r=0.513).Multiple-flower has 10 sepals while simple-,double-flower always has 5 ones.
