This paper presents the findings of a study on two quality protein maize (QPM) varieties— Srikandi putih-1 (white kernels - for food) and Srikandi kuning-1 (yellow kernels - for animal feed). The research was based on two sets of experiments that were compared with the normal check varieties—22 populations of yellow QPM and 10 populations of white QPM. Each set used a randomized complete block design with three replications in 11 locations of central maize areas in Indonesia during 2002 and 2003. The stability model showed that genotype and environment interaction was significant for grain yield. The potential grain yield for Srikandi putih-1 was 7.91 t/ha or 13.4 per cent higher than the normal maize. Grain yield of Srikandi kuning-1 was 7.92 t/ha or 2 per cent higher than normal maize check variety Bisma. The white and yellow QPM varieties possessed lysine concentration of 0.36 per cent and 0.45 per cent and tryptophan concentration of 0.07 per cent and 0.085 per cent, respectively. Both maize varieties were subsequently released in 2004 as the first national QPM varieties.
