The paper analyzes historic wheat trials to show how vrn1 and Ppd1 alleles affect yield through environmental interactions, finding that vrn1 effects are more variable than Ppd1 effects.

The paper estimates the yield effects of awns in wheat under different environmental conditions over 12 years in the Southeast US, finding awns improve yield in heat-stressed environments.

The paper identifies major and novel QTL for plant height and heading date in wheat using a biparental population, showing that genetic variation is dominated by known variants and moderate-effect QTL.
