Abstract
A “small fruit” condition of apples with symptoms resembling those caused by chat fruit virus has been found on Red Dougherty in Hawke's Bay and on Delicious and Sturmer in Otago. On affected trees the fruit which carry the normal number of seeds are small at harvest time, averaging only 30% to 40% the weight of fruits from healthy trees. On Delicious, affected fruits lack colour, and affected Sturmer trees tend to have an upright habit. In transmission trials with Red Dougherty preliminary results indicate that the condition is transmissible from diseased to healthy trees.
