Abstract

Somacional variation and eyespot toxin tolerance in sugarcane.

Abstract

A very high frequency of toxin-tolerant variants was found among 480 culture-derived Q101 plants analysed for their reaction to the toxin produced by Helminthosporium [Drechslera] sacchari. Their distribution was biased towards tolerance in plants regenerated from cultures exposed to toxin selection. The results are discussed in relation to the possibility of using consecutive cycles of culture to 'stack' improved characters into a sugarcane cultivar.
