Genetic Enhancement of Dry Bean for Improved Production on Degraded Soils
Grain Legume Genetics Physiology Research
2013 Annual Report
1a.Objectives (from AD-416):
Use plant breeding to develop dry bean lines with better performance on degraded soils in Feed the Future countries including Haiti, Malawi, Mozambique, and Tanzania.
1b.Approach (from AD-416):
Collections of bean accessions will be screened under low fertility, drought, root rot, and related stresses. Promising materials will be used in crossing to introduce stress tolerance into native landrace and improved dry bean cultivars representing typical market classes in each country. Graduate students from the respective countries will be trained in plant breeding and genetics and soil fertility
Six (Haiti, Tanzania-2, Washington-3) field research sites were initiated during Spring-Summer 2013 to screen, characterize and validate tolerance of select common bean accessions to low fertility soils. Soils across these test sites were low primarily for N (less than 25 lbs/A) or P (less than 10 ppm/A) or for both elements. This project contributes to Subobjective 1A of the in-house project: Generate molecular markers in beans and peas with application for MAS of resistance to bacterial, fungal, and viral diseases and tolerance to drought and low soil fertility.
