Abstract
The number of ovules of the first ear of maize (Zea mays L.) at silking time was studied on three single crosses ranging from very early flint to late maturing, in three locations, from the northern limit of culture for grain to good irrigated conditions of the southeastern part of France. The results show that the ovule number is mainly determined by genotypes and increases with lateness; means are as follows: F7 × F2, 338; WH × WJ, 448; W64A × F546, 589 ovules. The variation among environments is characterized by a CV of 9% but is not significant. Nevertheless a part of this variation seems to be explained by the duration, in terms of heat units, of the sowing-silking period.Key words: Zea mays L., ovule number, genotype-environment interactionThis publication has 2 references indexed in Scilit:
