Evaluasi Stabilitas Hasil Jagung Hibrida Menggunakan Metode Genotype and Genotype by Environment Interaction Biplot (GGE BIPLOT)

Abstract

<p class="Abstrak">Visualization of GGE biplot analyses was able to explain the genotype by environment interaction. This research was aimed to determine the yield stability of promising experimental maize hybrids in eight locations based GGE biplot method. Ten promising experimental maize hybrids and two commercial hybrid varieties as check, namely: HBSTK01, HBSTK03, HBSTK05, HBSTK06, HBSTK07, HBSTK08, HBSTK09, HBSTK10, HBSTK11, HBSTK13 and Bima 16 and Pertiwi 3 were evaluated in eight locations, ie. Bangka (Bangka Belitung), Probolinggo (East Java), Minahasa Utara (North Sulawesi), Donggala (Central Sulawesi), Soppeng, South Sulawesi, Gowa (South Sulawesi, Konawe (Southeast Sulawesi)and Lombok Barat (West Nusa Tenggara) from May to October 2013. The treatments were arranged in a randomized complete block design (RCBD) with 3 replications. Variable measured was grain yield. Analysis of variance was performed for data from each study site, to determine the performance of each genotype at each location. Yield stability analysis was performed by GGE biplot method using PB tools software. Results showed that genotype H9 (HBSTK11) had the highest biological stability with grain yield of 10.37 t/ha, higer than the overall mean yield. The best hybrid with the highest yield and good stability was hybrid H6 (HBSTK08) of 11.08 t/ha. This experimental hybrid is considered potential to be released as new hybrid variety. North Minahasa is considered the most suitable location for testing, whereas Konawe and West Lombok are least suitable, compared with the other locations.</p>

Description of maize check genotypes stability for selection on tidal swamp-land for grain production

“…Meanwhile, the environment has contributed to the variance by 10.90%. That means that genotype has high variation and yield performance primarily supported by genotypes characteristics [17]. Genotypes×location interaction shows significant statistically with the contribution to variation 8.52%.…”

Penampilan agronomi dan seleksi jagung hibrida pada lahan sawah tadah hujan dengan sistem tanam tanpa olah tanah

“…Tanaman yang tumbuh dilahan tanpa olah juga dapat tumbuh dan menghasilkan secara optimal (Nunes et al, 2018;Qin et al, 2006;Salem et al, 2015). Secara genotipik, karakter tinggi tanaman, tinggi letak tongkol berpengaruh langsung terhadap hasil biji (Priyanto et al, 2017). Sehingga karakter tersebut sangat penting dalam pengembangan jagung di lahan sawah dengan sistem TOT.…”

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

“…Yan and Tinker (2005) menyatakan bahwa sumbu AEA (sumbu X) memberikan gambaran rata-rata hasil, sedangkan sumbu Y merupakan garis tegak lurus terhadap sumbu AEA dan melalui titik asal biplot yang memberikan gambaran stabilitas agronomis. Priyanto et al (2017) dalam penelitiannya mengemukakan bahwa genotipe yang berada di sebelah kanan sumbu Y memiliki hasil lebih tinggi daripada rata-rata semua genotipe, sedangkan di sebelah kiri sumbu Y memiliki hasil di bawah rata-rata seluruh genotipe, serta semakin jauh jarak genotipe dari sumbu X semakin tidak stabil genotipe tersebut. Berdasarkan teori yang dikemukakan tersebut maka dapat diketahui bahwa hasil rata-rata tertinggi diberikan oleh hibrida Bonita IPB, diikuti oleh F5285290-290-2-1, Inul, dan Cakra Putih.…”
