Identifying key contributing root system traits to genetic diversity in field-grown cowpea (Vigna unguiculata L. Walp.) genotypes

摘要: Abstract Cowpea is a grain legume that grown extensively as an alternate protein and income source for many smallholder farmers. Characterising cowpea root phenotypes could provide the basis developing genotypes with system architecture (RSA) traits increase soil resource acquisition. Measuring RSA of any field crop demanding task, in terms expediency, time, cost, competence. Targeted phenotyping strategies focusing on few relevant might aid side-stepping some challenges associated roots crops. The objectives this study were to (i) measure genotypic variation shoot genotypes; (ii) identify candidate variables contribute largest share variance. Sixty accession trials at University Cape Coast, Ghana. Seventy variables, mostly quantitative measured. Multivariate analysis was used determine major contributing variation. There significant differences (P
