The winter nurseries allow for continuous operations and progress in the breeding program year-round. At the two Chile nurseries we evaluate 10,000 to 15,000 progeny rows each winter, grow and harvest 5,000 to 8,000 individual plants from 20 or more new populations to go into progeny row evaluations in Nebraska, and conduct yield tests on high-yielding advanced lines from our program under specific water treatments important for soybean production in Nebraska. At the Puerto Rico nursery we advance over 200 populations for two generations between October and May, conduct our main crossing for new research and variety development for all objectives under the lighted area, and evaluate 4,000...
