Relationship between lodging morphological characters and yield of varieties of maize zea mays


, : Relationship between lodging morphological characters and yield of varieties of maize zea mays. Journal of Agricultural Science 91(3): 633-638

Field experiments were carried out in the early and late growing seasons in the rain forest zone of Nigeria. Morphological characters associated with lodging were plant height, ear height and length of basal internode. There was a negative correlation between lodging and yield. Much of the lodging recorded, especially in the early growing season, was due to weak stems. Earliness, diameter of stem and leaf area had no relationship with lodging.

I. An analysis of relationship between the lodging grade and some morphological characters at early stages of plant development. Analysis of data from 26 varieties, grown under controlled conditions, revealed that, compared to lodging-susceptible varieties, lodging-resistant varieties were characterized by (1) a denser habit at the end of heading, (2) straighter, more tight...

Analysis of relationship between lodging grade and some morphological characters of spring barley varieties. Of eight varieties, Aramir, Gryf and Emir showed the least lodging. Analyses showed that lodging was correlated with stem length, the first internode length and diameter, and the wall thickness of the first three internodes. Broad-sense heritabili...
