Coffea arabica clones resistant to coffee leaf miner

Abstract

-Brazilian arabica coffee production is based on a set of highly

Adaptability and stability of organic-grown arabica coffee production using the modified centroid method

“…Moura et al (2013) reported variability among genotypes belonging to this group for rust resistance in organic farming, which should be considered when recommending these genotypes, since the use of agrochemicals to control diseases is not allowed in organic agriculture. Among the genotypes that make up this group, Obatã IAC 1669-20, Tupi, and IAPAR 59 stood out for presenting higher yields in the conventional systems; the first (Obatã IAC 1669-20) was classified as tolerant genotype (Mendonça et al 2016), and the last two (Tupi and IAPAR 59) were classified as coffee with resistance to rust (Shigueoka et al 2014). …”

Multiple resistance to bacterial halo blight and bacterial leaf spot in Coffea spp.*

“…In spite of some difficulties of this strategy, e.g., the existence of genetic barriers to interspecific crosses MONACO, 1968) and the long time required for the introgression of genes of interest and recovery of the recurrent genome, a C. arabica cultivar resistant to L. coffeella was developed in Brazil, by the transfer of resistance genes from C. racemosa (CARDOSO et al, 2014;MENDONÇA et al, 2016). Low-caffeine content cultivars were selected by hybridization of C. eugenioides in recombination with the species C. arabica and C. canephora (NAGAI et al, 2008).…”

IAC Catuaí SH3 - a dwarf Arabica coffee cultivar with leaf rust resistance and drought tolerance

“…The plant resistance to coffee rust was evaluated in the same experiments, on a 0-4 scale, where 0 and 1 were attributed to resistant; 2 to moderately resistant; 3 to moderately susceptible and 4 to susceptible coffee trees (Mendonça et al 2016). Coffee trees of cultivar Catuaí Amarelo IAC 62, in Mococa, SP and of cultivar Catuaí Vermelho IAC 99, in Franca, SP were classified as susceptible to coffee leaf rust, classified by 4 points on the disease severity scale.…”
