Characterization data of NPGRL cowpea accessions (2016-2017)
This dataset contains characterization data of NPGRL cowpea characterized during the period 2016-2017. The cowpea accessions were characterized based on IPGRI descriptors for cowpea (1983; 2009) and UPOV traits for yardlong bean (2009). NPGRL conserves, regenerates and characterizes cowpea germplasm first and foremost to support the plant breeders in their breeding efforts and other researchers.
