WCA - Groundnut Breeding PIP

PIP Workshop, 1-2 September 2016, Nairobi

Haile Desmae & Babu Motagi

Country strategies

Focus traits • Drought • Leaf spots (ELS and LLS) and rust • Aflatoxin • Rosette (GRD)

Improvement Plan

Objective

• continually improving the rate of genetic gain through release of new improved varieties in the region.

Improvement Plan…

• Breeding Pipeline

– Developing products that mitigate production constraints and meet client needs

1. Develop drought-tolerant breeding lines

2. Develop short duration (SD) breeding lines with moderate levels of resistance to rust, LLS and ELS

3. Develop SD and aflatoxin resistant, SD + drought tolerance, SD + high oil, SD + confectionery

4. Develop medium duration breeding lines (high levels of Rust, LLS, ELS, GRD resistance and other stresses)

Improvement Plan

• Widening genetic pool

– Increases in the number of crosses being made

• >250 pop

– Introduction from other programs (ICRISAT- Malawi & India and NARS)

– Utilizing the genetic diversity of groundnut (10,587 accessions) at Niamey

Improvement Plan…

• Optimization of selection strategies – Pedigree and its modification – SSD – F2 or F3 (early generation selection) or later

stage

• Speeding generation advance & phenotyping – Off season – Mesh house – Shuttle breeding (e.g. GRD & aflatoxin

phenotyping in Malawi; drought in Mali)

Improvement Plan…

• Optimization of testing strategies – Target environments

– Number of Entries

– Test environments and number of Location

– On-farm & on-station

– Number of Years

– Number of replications

Improvement Plan…

• Utilizing advanced statistical tools

– Mixed models

– Spatial analysis

Improvement Plan…

• Use of marker technologies – Focus traits (e.g. LLS, rust, oleate)

• Institutionalizing the application of BMS to enhance efficiency of data collection, analysis & management;

• Using modern tools like NIRS & XRF for accurate measurement of specific traits

• Utilizing Breeding Performance Assessment Tool (BPAT) to enhance breeding efficiency and guide product development;

Backstopping NARS

• Increased germplasm/breeding lines sharing with NARS

• Capacity building for scientists and technicians
