Multilocation trials are usually performed in breeding and variety evaluation programs to identify stable genotype(s) with similar crop performance in various environments. The present study evaluated the stability of six selected potato varieties (BARI Alu-7, BARI Alu-8, BARI Alu-25, BARI Alu-28, BARI Alu-36, and BARI Alu-41) suitable for multiple locations (Barishal, Bogura, Cumilla, Jamalpur, Jashore, Munshiganj, Mymensingh, and Rajshahi) in Bangladesh from 2014 to 2019. The study considered genotype and environment as treatments, year as replications and used a randomized complete block design (RCBD) with to construct the genotype plus genotype-vs-environment interaction (GGE) model. The joint analysis of variance revealed significant differences among the genotypes and environments (GE). The scores of PC1 (principal component 1) and PC2 (principal component 2) cumulatively explained approximately 63 % of the total variation in GE interactions and were used to construct the GGE biplot. BARI Alu-8 and BARI Alu-28 were the best genotypes, with high average yields and high stability across the locations. Jamalpur and Munshiganj was identified as the desired locations among the tested environments for growing all the genotypes. This study will help potato growers select highly stable high-performance varieties for a particular environment to achieve maximum tuber production. |
