biostudies-literatureUnknown12Baruah J<h4>Background</h4><i>Capsicum chinense</i> Jacq. (Ghost Pepper) is well-known for its high pungency and pleasant aroma. The recent years witnessed a significant decline in popularity of this important crop due to the use of inferior planting material and lack of elite lines. To maintain constant performance across a variety of settings, it is crucial to choose stable lines with high yield and capsaicin content, as these are the most promising traits of Ghost Pepper.<h4>Method</h4>In this study, 120 high-capsaicin genotypes were subjected to a 3-year (<i>kharif</i> 2017, 2018 and 2019) stability investigation utilizing two well-known stability methods: Eberhart-Russell (ER) and additive main effects and multiple interaction (AMMI).
