Stability and Adaptability of Yield among Earliness Sweet Corn Hybrids in West Java, Indonesia

Abstract

Multienvironment testing is an important phase to study the interaction of G × E and to select stable hybrids for a broad environment or for a specific environment. To study the interaction of G × E and the stability of earliness and yield of Indonesian new sweet corn hybrids under different locations and seasons in West Java, Indonesia, eighteen hybrids were evaluated in six environments in West Java, Indonesia, and were analysed using parametric and nonparametric stability models, additive main effects and multiplicative interaction (AMMI), and GGE biplots. Results showed that the most promising sweet corn hybrids including hybrids G5 (SR 24 x SR 17) and G11 (SR 31 x SR 17) were identified. The parametric and nonparametric stability parameters and ASV were complement to the AMMI and GGE biplots in selecting stable and adaptable hybrids in terms of earliness and yield. G5 was selected as a high-response hybrid for grain yield to Jatinangor (E1, E2), Lembang (E3, E4), and Wanayasa (E5, E6), as well as earliness to Jatinangor (E2), Lembang (E3, E4), and Wanayasa (E5, E6). G5 sweet corn hybrid, therefore, is suggested to be extensively evaluated on farm and produced for smallholder farmers in West Java, Indonesia.

GGE Biplot Analysis for Stability and Adaptability of Maize Hybrids in Western Region of Indonesia

“…Table 4 provides significant differences between environments for maize hybrid yields (p < 0.01 and p < 0.05). e differences in environmental conditions were also reported by several researchers including [8] on durum wheat, [19] on peanut, and [13] on sweet corn hybrid. e highly significant differences (p < 0.01 and p < 0.05) between the maize hybrids tested are given in Table 5.…”

“…International Journal of Agronomy tence of important yield variations among hybrids tested for different conditions [13,21,22]. Significant effects of environment explained that every location in Java and Sumatera were unique due to their different agroclimate.…”

“…Akinwale et al [7] summarized the display of GGE biplot for the following: (i) the polygon view that shows the winning genotype in different environments, (ii) the average tester coordination that ranks genotype based on their performance and stability across environment, and (iii) the vector view which shows the discriminating ability and representativeness of environment. GGE biplot had been used to evaluate various crops such as durum [8], lentil [9], maize [10], maize as a silage [11], sorghum [12], sweet corn [13], and sweet potato [14]. e objectives of the research are (i) to select superior maize hybrids with the best stability and adaptability in the western region of Indonesia and (ii) to determine the discriminant location for evaluating superior hybrids in the western region of Indonesia.…”

Identifikasi Stabilitas Hasil Genotipe Ubi Jalar (Ipomoea batatas L. (Lam)) Harapan Baru di Tiga Lingkungan

“…Efek GxE pada pengujian multilokasi terutama terjadi pada karakter kuantitatif termasuk hasil panen (Andrade et al, 2016a), serta resistensi terhadap faktor biotik dan abiotik (Dia et al, 2016). Saat ini telah banyak penelitian yang menggunakan kombinasi model stabilitas parametrik dan non-parametrik dalam menyeleksi genotipe stabil dan berdaya hasil tinggi, diantaranya pada tanaman buncis (Cicer arietinum L.) (Farshadfar et al, 2012), pada tanaman kacang rumput (Lathyrus sativus L.) (Ahmadi et al, 2015), pada tanaman gandum (Abate et al, 2015), pada tanaman jelai (Khalili dan Pour-aboughadareh, 2016;Vaezi et al, 2019), pada tanaman jagung manis (Ruswandi et al, 2020), dan pada tanaman ubi jalar (Maulana et al, 2020). Pada penelitian lainnya, Ajay et al (2020) berhasil menyeleksi tanaman kacang pada kondisi cekaman pospor di India dan Sabaghnia et al (2013) pada tanaman gandum di Iran dengan penggabungan berbagai parameter AMMI.…”

Evaluasi kegenjahan dan daya hasil jagung manis hibrida Indonesia menggunakan analisis GGE biplot pada lingkungan yang berbeda

“…Produksi dan produktivitas jagung manis dapat ditingkatkan dengan penggunaan varietas hibrida berumur genjah, peningkatan produktifitas lahan, dan rotasi kultivar hibrida berumur genjah yang adaptif terhadap lokasi dan musim tanam (Ruswandi et al, 2020). Kunci sukses dari strategi ini adalah adanya varietas hibrida jagung manis genjah yang berdaya hasil tinggi dan adaptif terhadap berbagai pola tanam dan musim.…”
