Correlation and Path Analysis for some Agronomic characters in Field Pea (Pisum sativum L.) Genotypes

Article in Press

Field pea is an important pulse crop in Ethiopia. However, the national productivity of field pea is low and thus knowledge on the nature and magnitude of character association and identification of important character is a prerequisite for the development of high yielding field pea genotypes. Hence a total of 49 field pea genotypes were grown in 7x 7 simple lattice design at two environments during 2018/19 main cropping...
