Performance of single cross maize hybrids during winter season of northern India

Published on

Nineteen maize single cross hybrids were evaluated in
northern India under severe cold stress in natural
conditions during rabi 2010-11. Data were recorded on
yellowing of leaves, drying of leaves and level of growth
at seedling stage at two stages viz. immediately after sever
cold and frosting, and after the temperature has slightly
increased to observe the recovery in maize plants. Vivek
Hybrid 9, Vivek QPM 9 and JH 3459 in early/extra-early
maturity, HM 9 in medium maturity and HM10 and Seed
Tech 2324 in late maturity group are suitable for sowing
in the winter season. Yellowing of leaves caused by cold
spell proved to be an important parameter to judge cold
tolerance at vegetative stage.
