Abstract
CABRERA TOLEDO, José Manuel; CARBALLO CARBALLO, Aquiles and ARAGON CUEVAS, Flavio. Agronomic assessment of tiny Zapalote race maize in the Isthmian region of Oaxaca. Rev. Mex. Cienc. Agríc [online]. 2015, vol.6, n.spe11, pp.2075-2082. ISSN 2007-0934. https://doi.org/10.29312/remexca.v0i11.775.
In order to understand the behaviour of outstanding stocks of tiny Zapalote race maize, agronomic assessment of 18 outstanding landrace was performed. The outstanding stocks have been characterized and preserved, while advances in the selection and breeding of top four varieties. Field assessments were developed for four crop cycles in the experimental fields of Comitancillo Institute of Technology, Oaxaca. 10 variables were recorded. The experimental design was completely randomized with two replications. The results showed highly significant differences for varieties, crop year and for the interaction of both factors on grain yield, days to male flowering, and days to silking, plant height, ear height and width of grain. The main conclusions are: 1) The yield of grain varieties and years ranged from 1.73 to 2.97 t ha-1 and; 2) In the region, there is wide genetic variation among and within populations of tiny Zapalote race maize.
