Characterization data of NPGRL cowpea accessions (2012-2014)

2018

The dataset contains morphological descriptions of cowpea accessions conserved at NPGRL. NPGRL regenerates and characterizes plant germplasm primarily to assist the breeders and other researchers. The descriptors used in the characterization are based on IPGRI descriptors for cowpea (1983; 2009) and UPOV traits for yardlong bean (2009).
