Maize is widely cultivated throughout the world, and a greater weight of maize is produced each year than any other grain. [79] In 2020, total world production was 1.16 billion tonnes , led by the United States with 31.0% of the total (table).
Teosintes strongly resemble maize in many ways, notably their tassel (male inflorescence) morphology. Teosintes are distinguished from maize most obviously by their numerous branches each bearing bunches of distinctive, small female inflorescences. These spikes mature to form a two-ranked 'ear' of five to 10 triangular or trapezoidal, black or ...
The speciation and evolution of maize varieties in Italy, by means of man-made adaptive selection, maintained a broad genetic variability for about four centuries. . Traditional varieties and ecotypes were sown in the diversified ecological regions of Italy until the introduction of Corn Belt hybrids in the twentieth century presented outstanding ecological adaptation, yield and cooking char
Tito Vezio Zapparoli (1885–1943) was an Italian agronomist and plant breeder.. After graduating in agriculture, he studied the agronomic and morphological characteristics of traditional varieties of maize.
One important and unique event in plant morphology of the 21st century was the publication of Kaplan's Principles of Plant Morphology by Donald R. Kaplan, edited by Chelsea D. Specht (2020). [36] It is a well illustrated volume of 1305 pages in a very large format that presents a wealth of morphological data.
This classification increases understanding of the morphological characters of any particular family. As a disadvantage, this classification crops with different economic uses and morphological and other agrobotanical peculiarities when brought under one family do not generally bring out the economic importance of the individual crops.
The classification of Ecuadorian maize was based on the following data; location and environment (altitude and photoperiodic response included), plant and ear characteristics, cytological analysis of the chromosomes, and historic and ethnographic information concerning the crop.
McClintock explored the chromosomal, morphological, and evolutionary characteristics of various races of maize. [60] [32] After extensive work in the 1960s and 1970s, McClintock and her collaborators published the seminal study The Chromosomal Constitution of Races of Maize, leaving their mark on paleobotany, ethnobotany, and evolutionary ...
