Abstract

Studi stabilitas hasil merupakan tahapan penting dalam menyeleksi hibrida superior yang beradaptasi luas ataupun yang beradaptasi sempit (spesifik lokasi). Tujuh genotip hibrida jagung diuji multilokasi di delapan lokasi yang bervariasi dan tersebar di berbagai wilayah Indonesia dengan tujuan menduga interaksi genotip x lingkungan, stabilitas dan adaptabilitas hasil (ton/ha) dalam rangka pengembangan varietas unggul di Indonesia. Di setiap lokasi, sebuah percobaan dengan tujuh hibrida DR dan empat hibrida cek dilaksanakan dalam rancangan acak kelompok, diulang tiga kali. Data dianalisis dengan analisis varians, analisis varians gabungan, least significance increase (LSI), dan analisis model additive main effect and multiplicative interaction (AMMI). Hasil penelitian menunjukan bahwa interaksi genotip x lingkungan untuk karakter hasil tanaman jagung merupakan fenomena yang nyata. Hibrida yang memperlihatkan hasil yang tinggi dan stabil adalah Var B, G, dan F. Hibrida unggul spesifik wilayah antara lain: Var E dengan lokasi Klaten dan Var H pada lokasi Jatinangor. Var C beradaptasi spesifik pada lokasi Boyolali.

Abstract

Study adaptability is an important step to select superior hybrids which have wide adaptability or specific adaptability. Fifhteen of DR Unpad hybrids have purpose to know about stability and adaptability for yield characters (yield ton/ha), ear weight of plot (kg), ear weight of sample (kg), and grain weight of sample (kg) of DR Unpad hybrids in East Java and to determine GxE interaction on two plant seasons for build up superior variety in Indonesia. Three location and each location two seasons, fifhteen hybrids and four tester cultivar were tested and randomized complete block design with three replications. Data were analysis of variance, complete analysis variance, and AMMI. The results indicated that there was GxE interaction  for yield character. Thus, for yield performance, hybrids Var R showed high stability and high yield. Var R, C, and Var G have a wide adaptability for yield. Var C and R had specific  adaptation in marginal location in Sidoarjo  on second season. And hybrids Var F and Var B specific for Ngronggot on second season which that location was a good environment.
