High-density genetic mapping for coffee leaf rust resistance

Abstract: Coffee leaf rust caused by the fungus Hemileia vastatrix causes considerable economic losses for coffee producers. Although agrochemical products can provide sufficient disease control, the use of resistant cultivars is a safer alternative. This resistance may be constrained by one or a few genetic factors, mainly those found in material originating from interspecific hybrids. In this study, the genetic analysis of an F 2 population consisting of 224 plants derived from a crossing of Híbrido de Timor UFV 427-1… Show more

“…Thus, rice production must be increased by 70% until 2050 to supply the growing demand for food, take into account the growth population and economic development (Godfray et al, 2010). Additionally, there is a consensus that in the future the climate changes will become a bottleneck for crop yield and its stability (Brito et al, 2010(Brito et al, , 2016Diola et al, 2011Diola et al, , 2013Guimarães et al, 2017;Weber et al, 2014). In this way, projected climate changes could reduce crop yields in the future (Fan et al, 2016;Tian et al, 2015).…”

“…Seleksi terhadap serangan penyakit diarahkan terhadap serangan penyakit utama pada tanaman kopi, yaitu penyakit karat daun. Penyakit karat daun yang disebabkan oleh Hemileia vastatrix merupakan penyakit yang sangat merugikan pada tanaman kopi (Semangun, 2000;Diola et al, 2011;Rodrigues et al, 2014). Penyakit ini sudah berkembang di Indonesia sejak tahun 1876 dan dalam perkembangannya mengakibatkan penurunan produksi kopi hingga 25% (Semangun, 2000) dengan tingkat kerusakan mencapai 58% (Rosmahani, Rachmawati, Sarwono, Soleh, & Jumadi 2003).…”

“…vastatrix dapat menginfeksi semua jenis kopi (Coffea arabica, C. canephora, C. liberica, C. excelsa dan C. congensis) (Semangun, 2000), dan mempunyai ras fisiologi yang banyak sehingga ketahanan kopi terhadap penyakit karat daun menjadi sangat kompleks. Menurut Rodrigues et al (1975) cited in Silva et al (2006) pada tanaman kopi terdapat gen-gen yang menentukan ketahanan terhadap karat daun yaitu, gen SH, sedangkan pada H. vastatrix terdapat gen-gen yang menentukan virulensi, yaitu gen v. Menurut Silva et al (2006) dan Diola et al (2011) pada kopi telah diidentifikasi 9 gen ketahanan yang bersifat dominan (major gene), yaitu SH1-SH9. Gen SH1-SH5 ditemukan pada kopi Arabika dari daerah Ethiopia, gen SH3 ditemukan pada kopi Liberika, sedangkan gen SH6-SH9 ditemukan pada kopi Hibrido de Timor (C. arabica × C. canephora).…”

“…Abiotic and biotic stresses represent the major constraints that result in agricultural losses on the global scale and projected climate changes could increase their negative effects in the future (Brito et al, 2010(Brito et al, , 2016Diola et al, 2011Diola et al, , 2013Weber et al, 2014;Guimarães et al, 2017). Recently, reports are highlighting via climate models predict an increasing frequency and intensity of heat waves and high temperature events throughout current century (IPCC, 2013;Becklin et al, 2016).…”
