Indirect Selection on Roots And its affect on nutrition

Many breeding programs have focused on improving shoot architecture for increased production, and dry bean is no different. Over the last 100+ years, breeders have targeted a short, indeterminate bush shoot a

Natural Selection on Roots In two genepools

Dry bean has two genepools. The roots in these gene pools are similar.

Root Architecture for Resilience to FRR

Root architecture has been shown to influence root rot severity. Weijia Wang, a graduate student in the Cichy lab had previously screened an Andean by Middle American population for FRR resistance. We took the extreme RILs from each group and Root architecture can be a complementary breeding target for improving root rot tolerance. Root growth in early season (V1) is the time for screening. The greatest difference between resistant and susceptible lines can be found in basal roots.

Field Plants

Susceptible lines have little root mass.
