Discussion
S. Hanounik
Do you have any plans to improve frost tolerance of ILC 482 through crossing
with say ILC 202 which according to your data was rated I at different stages
of frost occurrence?
K.B. Singh
After identifying ILC 202 as frost tolerant, we have utilized this genotype in
crossing with ILC 482 and other high-yielding lines. Our biggest dilemma at
the moment is how to screen for frost tolerance in segregating generations
especially in view of the uncertainty of occurrence of late frost. While selecting
plants in segregating generations for other characters, hopefully, we may
inadvertently select for frost tolerance. Once screening methods are devised,
evaluation will be easy.
M. Kamal
Is it better to do screening for cold tolerance in a chickpea growing area where
frost occurs more frequently?
K.B. Singh
Yes, that would provide more reliable information. But do we know such
places? My request to the participants would be to let us know if there are
places where late frost isof common occurrence and chickpeas can be grown.
