Preliminary Yield Trial
To demonstrate that PHILSURIN is continuously pursuing its mandate of developing superior varieties, rapid multiplication of promising entries from the Advance Yield Trials (AYT) are veing done, nurseries are expanded for mass propagation and Yield Verification Trials (YVT) are being conducted in 14 locations to get the commercial data of both PSR promising clones and Foreign varieties.
The multi-location testings are usually carried out in cooperation with the MDDC Extension personnel which is the MDDC Coordinator.
The first multi-location test is the Preliminary Yield Trial or PYT. About 25 to 30 entries are accommodated, and each entry is planted on a 6 x 5 m plot. The general stand of the entry is evaluated on the 8th month and yield parameters are measured at harvest. PYT is conducted in four major sugarcane growing areas in Luzon, Visayas and Mindanao.
