AMMI and GGE Biplot Analysis of Yield and Related Traits among Selected Mini-core Pigeonpea (Cajanus cajan L. Millsp.) Accessions

Pigeon pea [Canjanus cajan (L.) Millsp.] is an orphan crop that has remained greatly unimproved in quality and quantity Africa even though it great potential of supplying food to the growing population. Its yield affected by various biotic abiotic factors a lack varieties with broad adaptability range environments. It therefore important select accessions are stable different environments for components. A randomized complete block design layout was used carry out multi-locational trial using 107 pigeon accessions. Data taken total number pods per plant at maturity, pod length, seed weight, seeds pod, plant. Additive main effects multiplicative interaction (AMMI) genotype environment (GGE) biplot were interpret data. The mean squares PCA explained first two principal components account 100% G x E interaction. results revealed differences across three locations mostly due genotypes some extent Six observed be high-yielding all
