Early in the 20th century, a collection of fire blight resistant pears from around the world was assembled in southern Oregon in efforts to develop improved rootstocks. ‘Old Home’ and ‘Farmingdale’ are two cultivars from Illinois that exhibited fire blight resistance and useful horticultural traits. Both became important as interstem stocks and as...

... and Discussion DNA fingerprints. Each of the 12 cultivars and OH×F selections were uniquely identi- fied except for the three OH×F 69 selections obtained from different sources which had identical fingerprints (Fig. 3). All OH×F se- lections shared an allele with 'Old Home' at each of the 12 loci with two exceptions: OH×F 87 was homozygous for 117 at EMPc117 and did not have the 119 allele from 'Old Home'; and OH×F 333 did not have the 135 or 159 alleles present in 'Old Home' at CH01d09 (Table 3). Neither of the two alleles at four SSR loci (EMPc117, ...

In the present study, five SSRs from a novel set of microsatellite loci and
8 previously isolated are analyzed in different species and cultivars of Opuntia,
selected from two ‘on field’ collections located in Italy and Argentina. The objectives
were to investigate the genetic variability in the cactus pear and assess the ability of
the tested SSR...
The Sardinian pear germplasm is an important resource of genetic diversity that can be used for increasing data on European pear germplasm, to optimise the efficiency of the association studies within the genome and to identify genomic regions that control the main horticultural traits. A set of 108 Sardinian pear genotypes, composed of 81 Pyrus co...
Pyrus pyrifolia is considered one of the most important cultivated Pyrus species. Hundreds of landraces and bred cultivars have been developed through the natural and artificial hybridizations necessary due to self-incompatibility. In this study, the genetic diversity of 478 Pyrus accessions, including Chinese landraces, bred cultivars, and wild sa...
