S. D. Valya is a hardy pear selection from South Dakota breeding work on fire blight resistant pears. It is described as a 1938 pear from a Lincoln x Russian Sand cross. The bulletin identifies it as the reciprocal hybrid of Sladky. [S1]
The entry places it in a program meant to combine the hardiness and fire blight resistance of East Siberian and North Chinese pears with the larger fruit and quality of cultivated European pears. In that context, S. D. Valya appears as a named South Dakota selection, not a casual seedling. Its parentage and reciprocal relationship to Sladky are preserved in the printed record. [S1]
The fruit is described as nearly two inches across, round and tapering toward the stem, with yellow skin marked by minute russet dots. The bulletin calls the quality good. [S1]
Tree notes are brief but useful. The tree is described as good, free of blight, and productive enough to bear a heavy crop in the drought year 1936. [S1]
The same source places S. D. Valya among pears described as resistant or immune to fire blight, and its own entry says no blight. The bulletin does not give a formal hardiness zone for this cultivar, but it belongs to a South Dakota program focused on hardy pears for the northern plains. [S1]
Its lineage matters because the cross links Lincoln with Russian Sand pear. The note that it is the reciprocal hybrid of Sladky shows that the two cultivars were paired in opposite crossing directions. This makes S. D. Valya part of a deliberate breeding line, not an isolated named fruit. [S1]
