Barley (Hordeum vulgare) and Kiwicha (Amaranthus caudatus) Improvement by Mutation Induction in Peru

  • 1. Cereal Research Programme, Universidad Nacional Agraria de La Molina, Lima (Peru)

Description

In order to increase food availability and household incomes of families in the Andean region of Peru, a mutation induction method was applied to improve barley (Hordeum vulgare) and kiwicha (Amaranthus caudatus) cultivars. Barley cultivar Buenavista was treated with 200 and 300Gy inducing different kinds of mutations. Twenty promising mutant lines were selected and have been evaluated at the national trials. From them Mbv-Earlier, from 300Gy dose was selected and released in 2006 as a new cultivar denominated Centenario. This cultivar has a high yield potential (5,552 kg/ha), resistance to stripe rust (P. striiformis f sp hordei) and better food quality than the parental cultivar. Kiwicha traditional cultivar Seleccion Ancash treated with 400Gy , identified a higher yield mutant denominated Centenario Cultivar. At farmer location in the coast the yield has a variation of 3,500 to 5,500 kg/ha and in the highland from 2,500 to 3,700 kg/ha. The better yield potential, tolerance to Sclerotinia sp, color and size of its grains have contributed in the preference of Centenario over other commercial cultivars. (author)
