However, the poor ability of
N11 to recover from drought that went undetected at
Pongola, was evident in the rainfed trials. Two varieties of
similar growth habit, N7 and N12, emerged as the most
tolerant of drought and they appeared to recover quickly
once stress was relieved. N13 also tolerated drought well
and with N12 it usually outyielded the other varieties under
conditions of stress.
