Opportunities for Biotechnology Research on Sorghum Stalk Rot and Virus Diseases
Giorda, L.M. & Martinez, M.J.
Abstract
Although considerable progress has been made using conventional
technology in identification and characterization of viral and
stalk rot diseases of sorghum, there is still an incomplete
understanding of the genetics of resistance, and many viral
diseases remain uncharacterized. Biotechnology (cDNA) will play
an increased role in virus detection and identification, and in
marker assisted selection in breeding for sorghum virus
resistance, and to discern the genetic basis of resistance to the
stalk rot complex quickly and more precisely. Biotechnology will
also aid in the identification of quantitative trait loci (QTL)
associated with specific Fusarium and Macrophomina stalk rots
responses and drought tolerance.
Keywords
cDNA, conventional breeding, drought tolerance, marker assisted selection, virus resistance

Résumé
Bien que des progres considerables aient ete realises avec la
technique conventionelle d'identification et de caracterization
des maladies virales et de stalk rot de sorgho, il reste a
comprendre la resistance genetique et a caracteriser beaucoup de
maladies virales. La biotechnologie (DNA) jouera un role
preponderant dans la detection et l'identification des viroses,
dans l'amelioration de la resistance aux virus a l'aide de la
selection, grace aux marqueurs et dans la determination rapide
et precise des bases genetiques de resistance au complexe stalk
rot. La biotechnologie aidera aussi a l'identification de traits
quantitatifs (QLT) au loci associes au fusarium et au Macrophomia
stalk rots et a la tolerance a la secheresse.
Mots Clés
DNA, amelioration conventionnelle, tolerance a la secheresse, selection avec marqueurs, resistance a la virose
