The content of the nutrition depends on the genotype, environmental conditions, and the fruit ripening phase at harvest. In Indonesia, there are many local varieties or landraces of chili that have adapted well to the local environment. Local varieties are good genetic resources for developing new superior varieties of chili that have the quantity, quality, and resistance to environmental stress.

Penelitian ini bertujuan untuk mengetahui penampilan dan korelasi genotipe dan fenotipe galur mutan jagung inbred (M1). Sepuluh galur mutan jagung inbred (M1) ditanam dalam Rancangan Acak Kelompok (RAK) yang diulang 3 kali. Hasil penelitian diperoleh perbedaan fenotipe dari sepuluh galur mutan jagung inbred (M1) untuk karakter tinggi tanaman, jumlah daun, waktu munculnya bunga jantan, bunga betina, dan berat biji. Korelasi genetik berkorelasi sempurna (+1) pada karakter antesis dengan saat masak tongkol dan silking dengan saat masak tongkol. Tinggi tanaman berkorelasi signifikan dengan jumlah daun dan berat brangkasan; sedangkan berat biji memiliki korelasi genotipe yang signifikan dengan jumlah daun, antesis dan berat brangkasan.
