Grain filling patterns of CIMMYT early maize inbred lines
Abstract
100 words
Despite the ability of early maize to escape drought and provide
food early, it yields 20-30% less than late maize. The challenge
is to increase yield while maintaining earliness. A study is ongoing
at CIMMYT, Harare to determine whether grain fill rate
and duration can be used as selection criteria for yield. Fifteen
early maize inbred lines characterized revealed genetic variations
in grain fill rate and duration that was correlated to yield implying
that they are a better method for indirect selection for yield.
Therefore, a great potential for increasing the yield of early
maize exist using indirect selection methods.
