Analisis Stabilitas Parametrik Hasil Cabai Rawit (Capsicum fructescens L.) pada Empat Lokasi Dataran Rendah

Abstract

Stable and high yielding chili varieties are needed to increase national chili production. The objective of this study was to identify the stability of sixteen chili (Capsicum fructescens L.) genotypes using parametric stability analyses (Francis-Kannenberg, Wricke, Finlay-Wilkinson, AMMI, and GGE). The study was conducted from August 2018 to September 2019 in Kolaka, Palembang, Aceh, and Bogor. The experiment used a randomized complete block design with three replications. The chili genotypes evaluated were F5285290-237-6-1, F6285290-6-10-1-1, F5285290-290-2-1, F5285290-290-9-1, F5285290-290-9-3, F5321290-40-2-1, F5285290-123-6-15, F6321290-252-10-8-4, F5285290-38-6-3, F6321290-252-10-8-23, F6321290-252-10-8-75, Bonita IPB, Inul (loca1 variety), Cakra Putih (commercia1 variety), Taruna (commercia1 variety), and Tobasco. The genotype x environment interaction effect was significant on yield. Genotype F6321290-252-10-8-4 was identified as stable based on several parametric stability methods, but this genotype was not the highest yielding. Meanwhile, the GGE analysis revealed Bonita IPB as a stable genotype with the highest yield.
