Genetic Transmission of Bloom Date in Pears1

Year: 1976

Type: article

Abstract: Various pear species bloom at different times during the spring. Pyrus calleryana Decaisne is one of the earliest and P. communis L. is one of the latest blooming species. In 1975 there were 34 days between the earliest and latest blooming clones. When species or selections with different bloom times were crossed, two generations were needed to bring the bloom time of the progeny to the bloom time of the later blooming parent. The bloom of any given progeny occurred within only 4 to 5 days. No seedling in a progeny flowered later than the later blooming parent. Discovery of late blooming germplasm is essential for the development of late blooming types of pears.
