Abstract
In Mexico, there is a shortage of fresh corn ears selected
from landrace maize, so efficient selection strategies are
required to improve native maize with special traits. Hence, the objective of the present work was to evaluate 16 maize populations named RC1F2 selected for fresh corn quality from a composite of Raza Jala maize (C1SMJ). Planting was done in 2013, under rainfed conditions in four locations in the state of Nayarit, under a randomized complete block design with three replications. The useful plot consisted of four rows of 5 m long and 0.80 m between them. Agronomic and quality variables were measured. The improved populations RC1F2
were late and tall compared to the hybrid A-7573. In corn
length, 25% surpassed A-7573, while 69 % were equal in
soluble solids. In yield of tender ears, 58 % of the improved populations surpassed A-7573 on average with 2.156 t ha-1, which showed that the RC1F2 evaluated from the family selection practiced on the Jala variety (C1SMJ) favored the
accumulation of favorable alleles for corn size and quality
