IPR 107 - dwarf arabic coffee cultivar with resistance to coffee leaf rust

Abstract

-'IPR 107' was derived from a cross between ' is a dwarf medium size plant with medium precocity in ripening and with complete resistance to rust races in this time. This cultivar presents superior quality and high yield in many coffee regions.

Ciclo precoce de maturação dos frutos e produtividade em genótipos de café derivadas de C1195-5-6-2

“…Foram avaliadas 17 progênies F 1 RC 6 derivadas de retrocruzamentos (RCs) de diferentes genótipos de café arábica com uma planta F 2 do genótipo C1195-5-6-2 (Tabela 1). Como padrões comparativos foram utilizadas as cultivares IAPAR 59, IPR 99 e Catuaí Vermelho IAC 81 que possuem, respectivamente, ciclos de maturação precoce, semitardio e tardio (SERA et al, 2013).…”

Field Screening of Arabica Coffee Genotypes against Coffee White Stem Borer <em>(Xylotrechus quadripes) </em>and Leaf Rust <em>(Hemileia vastatrix</em>) Infestation in Kaski, Nepal

“…It affects mainly matured leaves and on severe stage can also infect young leaves causing leaf drop results to loss in production. Normally, yield losses per year due to coffee rust range from 30 to 90% depending on the environmental conditions during a given year (Sera et al, 2005), especially if not controlled by fungicide spray. The economic damage to world Arabica coffee production due to coffee rust has been estimated to be between $(US)1 billion and 2 billion per year (Van der Vossen, 2001) due to crop losses of 20-25% (Prakash et al, 2004).…”
