Title : On-farm performance of quality protein maize genotypes under rainfed hill environments of Nepal Material Type: printed text Authors: Upadhyay, S.R., Author ; D.B Gurung, Author ; Paudel, D.C., Author ; Pokhrel, B.B., Author ; K.B Koirala, Author ; Sah, S.N., Author ; Katuwal, R.B., Author ; Prasad, R.C., Author ; Dhakal, R., Author Pagination: 40-46 p. Languages : English (eng) Keywords: Genotype environment interaction, open pollinated varieties, quality protein maize. Abstract: Maize (Zea mays L.) is the second most important staple food crop after rice and a major food crop of the resource poor people in the hills of Nepal. Prevailing normal maize (non-QPM) is deficient in two essential amino acids: lysine and tryptophan. The majority of hill farm families are suffering from protein malnutrition as their major diet is maize and cannot afford animal protein. QPM (Quality Protein Maize) contains opaque-2, a single gene mutation that alters the protein composition of the endosperm portion and nearly double the essential amino acids concentrations than the normal maize grain……………….
