Abstract
The present invention relates generally to the field of plant breeding and concerns a method for determining the point at which a plant starts to flower. More specifically, the invention concerns a method for determining the start of flowering on an individual plant basis by measuring the reproductive structures of plants from digital images of these structures and deducing the start of flowering from the measurements and average growth rates. The invention also concerns apparatus for determining the start of flowering in plants, particularly in a high-throughput manner.
Claims11
A method for determining the start of flowering of an individual plant of a particular species, comprising:
- (i) digitally imaging inflorescence of an individual plant;
- (ii) measuring the inflorescence of said individual plant from the digital image;
- (iii) providing an average growth rate of inflorescence for said particular species of plant;
- and
- (iv) comparing the inflorescence of said individual plant measured in step ii) to the average growth rate of inflorescence provided in step iii) to determine the start of flowering of said individual plant.
An apparatus for high-throughput determination of the start of flowering of an individual plant of a particular species within a number of plants in containers, which comprises:
- (i) a transporter for supporting and moving containers in which the number of plants are growing and for positioning an individual plant for digital imaging;
- (ii) one or more digital cameras with sufficient resolution for imaging emerging plant inflorescences of the individual plant;
- and
- (iii) computer means associated with the at least one digital camera for detecting and measuring the plant inflorescence of said individual plant and comparing the measured inflorescence of said individual plant to the average growth rate of inflorescence for said particular species of plant to thereby determine the start of flowering for said individual plant.
