Evaluation of early orange varieties for valle of Mayo, Sonora

The productive reconversion in southern Sonora began with the planting of fruit trees such
as citrus fruits with an area of approximately 4,500 ha. Currently, producers' concern
about planting citrus species, especially orange, resurfaces and the question of which
varieties of early orange are best for southern Sonora is raised. In this work, the behavior
of the fruit quality variables of six early orange varieties was determined: Marrs,
Salustiana, Hamlin, Trovita and Cadenera on Carrizo pattern and also Hamlin on
Volkameriana; which are planted at a distance of 8 x 4 m, 3 plants were used for each
material, where each plant is a repetition; the experimental design used was completely
randomized with three repetitions. The variable evaluated and statistically analyzed was
the fruit quality with the variables weight per fruit (g), diameter (polar and equatorial),
seeds per fruit, juice per fruit (ml), percentage of juice, percentage of soluble solids, acidity
and Brix / acidity ratio.
The results obtained allow us to establish that in all varieties there is a good correlation
between the sensory attributes of acid and sweet taste with the% acidity expressed in
citric acid and the concentration of total sugars in g / 100 mL of juice and this is vital
importance because the ratio Brix / acidity is responsible for the taste that different
varieties have for the consumer.
