WebDec 1, 2024 · Phenotypic selection Waterlogging 1. Introduction Maize is largely grown as a rainfed crop in the Asian tropics and is prone to the vagaries of monsoon rains. As such, maize production is affected by an array of abiotic and biotic constraints. Plant species where normal mode of seed set is through a high degree of cross-pollination have characteristic reproductive features and population structure. Existence of self-sterility, self-incompatibility, imperfect flowers, and mechanical obstructions make the plant dependent upon foreign pollen for normal seed set. Each plant receives a blend of pollen from a large number of individuals each having different genotypes. Such populations are characterized by a high degre… i drunk driving swervin the masi
