| Sumario: | The intervarietal Cora hybrid of maize 2012 was developed
by the method of Reciprocal Recurrent Selection (RRS).
A heterotic pattern of P * A populations is used. The first
two cycles were with half sib progeny supported by corn
farmers from Nayarit, participatory breeding. From the
third cycle, progeny were from reciprocal full siblings
through crosses between lines S1
, type P S1 * A S1
. Cora
2012 was derived from the third cycle. The formation of
populations (1999-2001) and the implementation of RRS
(2002-2010) were performed in Nayarit. The evaluation was
conducted in Nayarit (2005-2010) and validation included
the states of Jalisco, Michoacán and Sinaloa (2010-2013).
The characterization was made in Nayarit (2010- 2011) and
was assigned as 'MAZ-1477-010313' in the record from the
Catálogo Nacional de Variedades Vegetales (CNVV). Is has
a similar behavior to current maize hybrids of 7 t ha-1. On
average, also have similar agronomic characteristics than
commercial hybrids. Its greatest attribute is that it yields well
even under changing climate factors, technology used and
soil. Seed production is relatively easy and yields around 4.5
t ha-1 of seed. Associated farmers and small seed companies
may use seed from parents |
