Evaluation of figs mutant selections cv. roxo-de-Valinhos
Universidade Estadual Paulista (UNESP)
The fig (Ficus carica L.), belonging to the Moraceas family, is one of the most important fruit crops, bringing Brazil to the condition of the tenth largest fig producer and exporter in the world. But the culture presents some problems with plant protection, and in Brazil, it is all implanted with an only cultivar, Roxo-de-Valinhos, which produces seedless fruit, not permitting the conventional improvement. In this sense, the genetic improvement by using mutagenic becomes a very important research line, that can greatly contribute to the culture development. Considering this, this study aimed to evaluate selections of fig originated from mutant plants formed by cuttings from buds irradiated with gamma ray and compare them with the main varieties of the culture in commercial plantation. By using plants originated from 5 traditional fig cultivars cuttings and 5 fig mutant selections (formed by cuttings from Roxo-de-Valinhos buds irradiated with gamma ray, in the dose of 30 Gy), spaced by 2.5 x 1.5 m. The experimental layout was a completely randomized block design, with 10 treatments, 3 repetitions and 5 plants per plot. The evaluations are made from the plants vegetative growth as well as the fruit characteristics. Through data analysis, it seems that there is variability between the mutant selections and with the traditional cultivars, and the treatment PI-189 was superior to the standard cultivar Roxo-de-Valinhos on great commercial characteristics importance, such as "number of fruit per plant", "average weight per fruit" and "productivity", having the same traits, showing itself with enormous potential for future studies.
