Abstract

GONZAGA NETO, LUIZ. Introduction and evaluation of white flesh guava (Psidium guajava L.) clones in the Submédio São Francisco river valley. Rev. Bras. Frutic. [online]. 2002, vol.24, n.1, pp.120-123. ISSN 0100-2945.  http://dx.doi.org/10.1590/S0100-29452002000100026.

With the objective of evaluating the genetic variability and selecting crop alternatives for "in natura" market of white flesh guava, 22 varieties from the IPA germplasm were introduced and evaluated in the Submédio São Francisco river valley. The plants were propagated through grafting, using four plants per variety in a 6.0m x 6.0m spacing. The following parameters were evaluated from 1993 to 1998: plant production (kg), number of fruits harvested per cycle and mean fruit weight (g). Among these parameters, mainly mean fruit weight (one of the most important parameters for table guava), the varieties Banaras and Luck Now showed the best performance for commercial purposes, with, respectively, 98.07 kg/plant, 813 fruits/cycle, mean fruit weight of 176 g, and 118.22 kg/plant, 940 fruits/cycle and mean fruit weight of 131.39 g. The variety Banaras had 11.1oBrix and TSS/Acidity ratio of 2.8 and Luck Now had 12.1o Brix and TSS/Acidity ratio of 3.0.
