Abstract

The relationship between growth cessation under shortening daylengths and chilling requirement was investigated in a low-chill, young peach seedling population and in 6 low-chill peach cultivars. A positive correlation (r=0.32°°) was found between growth cessation and chilling requirement in the seedling population, whereas, a negative correlation (r=-0.58°°) was found for the 6 cultivars. The 6 cultivars behaved in the manner that was expected; however, growth cessation in the seedlings was confounded by juvenility and vigor. Regression of individual progeny on their midparent values revealed that chilling requirement is highly heritable (h 2=0.93).
