Methods of predicting crop yield using metabolic profiling

摘要

The present invention relates to the fields of agriculture, plant breeding or genetic engineering for plants with increased yield, crop forecasting and crop management. In particular, the methods herein describe novel methods of predicting a plant's yield through the measurement of specific metabolites either individually or in combination with one another in a specific plant reproductive tissue. The plant predictive methods described herein may be used to predict yield of plant populations as well as allow for more efficient crop management practices (e.g. amount and timing of chemical applications or amount of irrigation water applied to a field).

主权项

1. A method of predicting yield in a plant, the method comprising;
a) sampling un-pollinated female inflorescence tissue from a plant; b) measuring one or more yield metabolite markers in the tissue of a); c) comparing the yield metabolite markers measured in b) against a calibration curve wherein the calibration curve correlates grain yield with the yield metabolite markers measured in un-pollinated female inflorescence tissue; and d) predicting grain yield in a plant.
