P7647 has proven itself to be a hybrid you can turn to on favourable sites, and the warmest less favourable sites. P7647 has given an 11% dry matter yield advantage over the Control hybrid in favourable PACTS trials.
P7647 is a tall, impressive stature hybrid that has demonstrated a very high silage dry matter yield potential in PACTS Trials with a good starch content.
On favourable sites it has given a dry matter yield 10% higher than the Control hybrid with a 2.3% lower dry matter content. It has maintained a high starch content of 36.9% at this very high dry matter yield level.
On less favourable sites P7647 has also given a dry matter yield 11% above the Control hybrid with a dry matter content of 32.8%, which was 1.9% less than the very early maturity Control hybrid, P7034.
Overall P7647 has been tested in the open in PACTS trials on 35 favourable locations and on 35 less favourable locations, both over four years. P7647 has been tested on ten locations under film over three years, and 14 locations over four years in PACTS grain trials.
In PACTS grain trials over 8 sites and three years of testing P7647 has shown promise for grain production. It has given an average grain yield 8% higher than the grain Control hybrid, P7326, with a grain moisture content 2.7% less.
P7647 has been tested over three years under film on 10 locations. It has produced high dry matter yields of a high dry matter content. It is an appropriate choice on favourable sites where good yield with a reasonable harvest date is sought. It could be an appropriate choice on the better less favourable sheltered sites.
Performance highlights:
* Score on a 1- 9 scale where 9 = very resistant
** Assumes plant establishment losses of less than 5%
*** Film penetration varies with conditions and film. Trials conducted with Samco and Maizetech films
