Abstract EN
Seed size plays a large role in determining productivity of large seeded legumes.
In many large seeded legumes such as pea and bean, actual yield, defined here as grain yield at harvest minus the weight of seed planted, is often a better measure of actual productivity than grain yield at harvest, because the weight of planted seed varies with seed size.
In many grain legumes, the weight of planted seed can be equal to 10% of the total grain yield, and minimizing the weight of planted seed could significantly impact actual yield.
This study produced an algorithm to examine the relationship between seed size, yield, and actual yield in silico.
The output of this algorithm predicted the ideotype for seed size in peas to be much lower (12.5 g./100 seeds) than the seed size of nearly all commercial varieties, indicating that efficiency in pea cropping systems could be increased by reducing seed size.
Modifications to the algorithm would allow the prediction of the ideal seed size in other legumes.
The algorithm predicts that there is likely very little correlation between seed size and grain yield, although larger seeded legumes will likely have a higher harvest index.
Plant breeders can use the ideotype predicted by this function to create varieties of peas and other large seeded legumes that have higher actual yield.
The ideotype for seed size was defined in pea.
