Genotyping / sequencing tools and services

Pigeonpea mid-density genotyping services

Genomics interventions in pigeonpea during the last decade, in particular the availability of a reference genome (Varshney et al. 2012) and whole genome sequence data on multiple lines, have enhanced the level of crop improvement(Varshney et al. 2017; Saxena et al. 2021). Cost-effective genotyping platforms are required to deploy genomics assisted breeding in routine crop improvement programs. Therefore, a mid-density genotyping platform has been developed targeting pigeonpea.

New pricing plan for genotyping services from April 2022

Over the last year, global supply chains and service providers have been affected by rising inflation, costs and challenges. Genotyping services and inputs in particular are affected by rising demand due to the global COVID-19 pandemic.

The CGIAR Excellence in Breeding Platform (EiB) has been proactive in maintaining the availability and quality of our brokered genotyping services throughout ongoing challenges. For 2022, there will be a small cost increase to our partners as a result of the higher prices charged by our trusted service partners.

Rice mid-density genotyping service

The 1k RiCA panel for rice is the mid-density genotyping panel developed at the International Rice Research Institute (IRRI) to enable affordable, efficient genomic selection. It has been implemented at several service providers and platforms, but currently is offered at Agriplex and DArT. Both platforms use custom amplicon workflows that reliably deliver almost all markers from all samples.

Basics of Genomic Selection 9. Computational Aspects and Implementation

Abhishek Rathore (ICRISAT)  presents the current state of tools for data management and genomic prediction available at ICRISAT and national programs in India. Abhishek presents a path to the proper implementation of data management tools that ensures the successful deployment of GS in breeding programs. Case examples of crops adopting these systems and their current state are also presented.

Groundnut mid-density genotyping services

Groundnut (Arachis hypogaea L.), also known as peanut, is cultivated over 34.1 million hectares with an annual production of 66.3 million tonnes (FAOSTAT, 2020). The availability of reference genomes for both the subspecies (A. hypogaea ssp fastigiata and A. hypogaea ssp hypogaea) of cultivated groundnut in 2019 have boosted more precise genomic studies and higher integration of genomic tools in the modern breeding programs across the world (Pandey et al. 2020).

African breeding programs leap forward by accessing new genotyping data

With newly accessible genotyping technologies, African crop breeding programs have partnered with EiB to start using genotyping resources to improve accuracy and efficiency.

As breeders strive for higher-yielding, climate-resilient and nutritious crops, genotyping is intensifying the speed and accuracy of achieving breeding goals. But new technologies have often been out-of-reach for national breeding programs in developing countries.
