Genomic selection was used in the Australian lentil breeding program to predict breeding values for traits like yield and disease resistance. By analyzing genetic markers, researchers could accurately estimate the potential of different breeding lines. The genomic selection approach led to higher accuracy in predicting traits compared to traditional methods, resulting in faster genetic improvement in lentil cultivars. This means that using genomic selection can help breeders develop lentil varieties that yield more, resist diseases better, and have improved seed quality traits.
