YIELD

‍Patwin-515HP is a semidwarf variety with an intermediate heading time similar to Patwin and Blanca Grande-515. In the 2016 Regional Trials, Patwin-515HP grain yield was higher than Blanca Grande-515 in the Sacramento Valley (~15%) and similar in the San Joaquin valley (Fig. 1). The average yield of Patwin-515-HP across 15 experiments was slightly higher (126 lbs/ac) than the original Patwin-515 (but not significantly).

QUALITY

Patwin-515HP showed outstanding bread making quality in evaluations performed by the quality Laboratory at the California Wheat Commission in 2013 and 2016 and by the milling industry at the California Wheat Collaborator Program in 2013. Patwin-515HP carries the GPC-B1 gene for high grain protein content. Across 15 experiments, it showed an average grain protein content of 13.8%, which was significantly higher than the original Patwin-515 (12.7%), which does not carry the GPC-B1 high grain protein gene.

AREA OF ADAPTATION AND PRIMARY USE

Patwin-515HP is very well suited for the Sacramento, San Joaquin and Imperial Valleys where it shows high yield potential under irrigation.  Its primary use is for bread production.
