Description The improvement of low nitrogen tolerant hybrid maize face on genotype x environment the genotype x environment interaction caused a genotype unable to maintain its appearance under suboptimal conditions. it caused the breeders difficult to choose varieties that are stable at optimal and suboptimal conditions. The using of simultaneous stability analysis methods can provide more authentic stability information. This study aims to 1) determine the yield stability of the promising low N tolerance hybrid maize varieties, 2) to obtain varieties that have high yield and stability and under optimal and sub-optimal conditions. This research was conducted at Bajeng Experimental farm, Gowa, South Sulawesi. The research was arranged in a split-plot design with two replications. Three levels of fertilizer N (N0 = 0 kg N ha-1, N1 = 100 kg N ha-1 and N2 = 200 kg N ha-1) as the main plot and 39 genotypes of maize (36 hybrids resulting from crosses of low N and 3 checks varieties Nasa 29, Bisi 18 and Jakorin 1) as the subplot. The variable measured was grain yield. The yield stability analyses were performed by Francis and Kannenberg, Finlay and Wilkinson, Eberhart and Russel, and GGE Biplot methods. The results showed that there were no genotypes stable in overall the four methods, but three genotypes considered as stable genotype based on two methods. H5, H6 and H15 genotype were the genotypes with high stability and high yield. The three genotypes had the opportunity to be released as a low Nitrogen tolerant maize hybrid.
Perakitan varietas jagung toleran Nitrogen rendah dihadapkan pada interaksi genotipe x lingkungan. Interaksi genotipe x lingkungan mengakibatkan suatu genotipe tidak mampu mempertahankan penampilannya pada kondisi suboptimal. Hal tersebut menyulitkan pemulia dalam memilih tanaman yang stabil pada kondisi optimal dan suboptimal Penggunaan beberapa metode analisis stabilitas secara simultan bisa memberikan informasi stabilitas yang lebih akurat. Penelitian ini bertujuan 1) mengetahui stabilitas hasil calon varietas jagung hibrida toleran N rendah, 2) Memperoleh varietas dengan stabilitas dan hasil tinggi pada kondisi lingkungan optimal dan suboptimal. Penelitian ini dilaksanakan di Kebun percobaan Bajeng Gowa, Propinsi Sulawesi Selatan,. Penelitian disusun dalam rancangan petak terbagi dengan dua kali ulangan. Tiga taraf pupuk N (N0=0 kg N ha-1, N1=100 kg N ha-1dan N2 =200 kg N ha-1) sebagai petak utama dan 39 genotipe jagung (36 hibrida hasil persilangan galur toleran N rendah dan 3 varietas pembanding Nasa 29, Bisi 18 dan Jakorin 1) sebagai anak petak. Variabel yang diamati adalah hasil biji pada kadar air 15%. Analisis stabilitas yang digunakan adalah metode Francis and Kannenberg, Finlay and Wilkinson, Eberhart and Russel, dan GGE Biplot. Hasil penelitian menunjukkan bahwa tidak ada genotipe yang stabil secara keseluruhan di keempat analisa yang digunakan, tetapi tiga genotipe stabil pada dua metode analisa stabilitas. Genotipe H5, H6 dan H15 merupakan genotipe dengan hasil dan stabilitas tinggi. Ketiga genotipe tersebut berpeluang untuk dilepas menjadi varietas jagung toleran N rendah.
