Propagation and ex situ conservation of maize landrace varieties under agroecological system

Abstract

Maize production is an integral and fundamental part of family farming, and the farmer has
acquired transgenic seeds subject to the dependence of associated acquisition of inputs, soil
contamination and loss of biodiversity. In this sense, the objective of this work was to propagate,
characterize and evaluate the conserved ex situ diversity of 15 peasants maize. Varieties
were propagated: Cateto, Burdock, Fortuna, Caiano, Aztequinha, Red, Purple, Cunha, Maizena,
Common Purple, Amarelão, Preto, White Pearl, Nutritional and Yellow. In the cultivation of
these varieties agroecological practices and increasing doses of biofertilizer (03%, 05% and
10%) were used throughout the development stages. The Yellow variety presented the best results,
with 100% germination, higher height and number of leaves, standing out from the other
varieties. In this context, it is concluded that it is possible to cultivate and conserve varieties of
peasants maize seeds in the Sertão Productive Territory
