Evaluación de materiales segregantes de plantas de tomate de árbol (solanum betaceum cav.) provenientes de cruzas interespecíficas con cyphomandra materna y cyphomandra uniloba, con posible resistencia y/o tolerancia a colletotrichum gloeosporioides “ojo de pollo”, en la estación experimental del Austro-INIAP

Abstract

The research was conducted at the farm in Bullcay INIAP, generally aimed to: assess segregating materials tree tomato Solanum betaceum Cav. from crosses between S. betaceum with C. maternal and C. uniloba tolerant "eye chicken "(Colletotrichum gloeosporioides Penz.) with good productivity, fruit size and quality, and as specific: 1) Select materials with improved tolerance and / or resistance (Colletotrichum gloeosporioides Penz) with promising yields and fruit quality for Bullcay area. 2) Determine the yield of each of the segregating material. 3) characterize agronomically segregating materials for this worked with 15 quantitative variables and four nominal for studied statistical analysis (PCA), and cluster analysis resulting in four main components, plus six clusters respectively. Best segregating materials were yellow and mottled skin Green UXB (R) XB (GA) "3 of 7", UXB (A) XB (GA) H9, while the crosses materials UXB (R) XB (GA), code "July 3" and UXB (A) XB (GA), H9 code showed the best performance of fruit per plant.
