Subject Chickpea
 
Description ,iVork is in progress at ICRISAT to identify and incorporate resistance to
Fusariuni wilt, Ascschyta blight, Botrytis g:e/ rnsuld and stunt, which are considered
to be most damaging to the chickpea crop. Fusariun wilt resistance has
been incorporated into high y;eld:n3 tlcsi and knhirli backgrounds, using donors
identified as highly resistant at ICRIS4T and other cjnters anl screening breed-
Ing materials in wilt;lc'c plots. M )re recf:nt;y, w3 have obtained evidence of
complenientarity between recessive genes csnfxring rd;ijta2ca injicating the
possibility of obtaining highly resistant segregants from crossbs among moderately
susceptible genotypes, thus making available a much wider range of backgrounds
than hithxto rele3sed. The inheritance of the other diseases is
not well ,understood. Ascochyta blight resistance is reported to be monogenic
and either dominant or rezessivz; manogenic inhetitanse m3y also
occur for chickpea stunt. Crosses have been made to incorporate resistance
to the other diseases into acla,3ted bazkgiounds and segrdaating p~pulations
screened in field nurseries in India and elsewhere.
