The aim of this study was to evaluate the coffee germplasm of the Parana Agronomic Institute (IAPAR) for resistance to the coffee-berry-borer. Preliminary field evaluation was performed in August 2004 and the fruits of less damaged genotypes in the field were evaluated under controlled condition with obligated and free choice experiments established in a randomized complete design with three replications. The genotypes were evaluated fifteen days after infestation with one borer per fruit in Petri dishes. The data were analyzed by the Scott-Knott means test at 1 % and by the χ2 test. Statistical analysis indicated that Coffea kapakata, Psilanthus bengalensis, C. eugenioides and genotypes with C. eugenioides genes were resistant. These genotypes presented low frequency of bored grains. C. eugenioides and C. kapakata could present resistance at epicarp level but not in the grain. P. bengalensis could present resistance also in the grains.

ABSTRACT SELECTION FOR RESISTANCE TO RUST IN PROGENIES OF COFFEE CULTIVARS IPR 99 AND IPR 107 All plants of the coffee cultivars IPR 99 (“Sarchimor”) and IPR 107 (‘IAPAR 59’ x ‘Mundo Novo IAC 376-4’) were resistant to rust ( Hemileia vastatrix ) in the past. Currently, susceptible plants were observed in the two cultivars due to the breakdown of resistance by new rust races. The aims of this study were: a) to identify coffee ( Coffea arabica L.) progenies of the two cultivars with resistance to rust; b) to identify progenies with incomplete resistance; c) to investigate the efficiency of test-crosses for selection from these cultivars. Evaluation for field resistance was carried out in adult plants subjected to natural infection by the local leaf rust population at IAPAR. Twenty-three test-crosses with F 3 progenies of ‘IPR 107’ and five with F 4 progenies of ‘IPR 99’ were evaluated. Moreover, 11 F 4 progenies of ‘IPR 107’ and five F 5 progenies of ‘IPR 99’ derived from self pollinations were evaluated. Several progenies of the IPR 99 and 107 cultivars presented high frequency of resistant plants and thus should carry additional S

The objective of this study was to identify progenies of Coffea arabica cv. IPR 100 with resistance to nematode Meloidogyne incognita race 1. The experiment was performed in greenhouse (Londrina, PR, Brazil) with an experimental design of randomized blocks with 3 replications and 15 plants per plot. Six progenies of cultivar IPR 100 were evaluated, and Mundo Novo IAC 376-4 cultivar was used as susceptible control. Five hundred eggs per plant were inoculated, totalizing 7500 eggs per plot of 150 cm2. The number of galls and egg masses in the roots were evaluated. All progenies of cultivar IPR 100 presented more resistance to M.incognita race 1 than the susceptible control.
