Enhancing crop genepool use: capturing wild relative and landrace diversity for crop improvement.

Book cover for Enhancing crop genepool use: capturing wild relative and landrace diversity for crop improvement.



Chapter 9 (Page no: 78)

Keeping a finger on the pulse: monitoring the use of CWR in crop improvement.

This chapter takes a macro perspective of the state of the use of crop wild relatives (CWR) in crop improvement programmes under the auspices of the Consultative Group on International Agricultural Research, with some supplementary perspectives from outside of the CG family where required. It asks, to what extent are CWR being used by crop scientists and pre-breeders today? A series of interviews was conducted with experts across 19 crop (wheat, rice tomato, oat barley, soyabean, banana, potato, maize, chickpea, cassava, lentil, sorghum, sweet potato, yam, pearl millet, finger millet, bean and cowpea) communities between February and April 2014. The results are compared with those reported in 1986 and 2007 by Prescott-Allen and Prescott-Allen and Hajjar and Hodgkin, respectively. The results highlight: (i) a positive trend in the overall use of CWR; (ii) a growing emphasis on their role in adapting cultivated crops to climate change; and (iii) that the majority of ongoing work with CWR has yet to result in quantifiable breeding outputs. Looking at (i), the genomics resources currently available to breeders, and (ii) the relative need for breeders to look outside of cultivated crops and landrace genepools for required greater genetic diversity, this chapter suggests that today's technological advancements coupled with more extreme environmental pressures will incite greater use of CWR in the coming years. Findings are relevant to the CWR conservation community advocating for increased investment into enhanced wild genepool conservation and use.
