The bulk of a corn kernel (which is technically the fruit of the plant) is amylose starch, a carbohydrate with a very simple structure, consisting of a string of 6-carbon glucose molecules attached end to end, i.e.

The study employs a detailed econometric approach and highlights the impact of gender in herbicide management. It stresses the necessity for better regulation of herbicides to mitigate health risks and improve agricultural outcomes.

It highlights the "refuge-in-a-bag" innovation in maize, integrating non-transgenic and transgenic hybrids to manage insect resistance. The chapter also features an Applied Learning Activity to analyze seed blend rationales through real-world examples.

It covers developing inbred lines for crops such as asparagus and cucumbers, highlighting flower types and seed generation techniques. Two hybrid seed production systems are detailed: the CMS system and the SPT system, with examples from canola and maize.

Breeders focus on performance evaluation across diverse sites, reducing test lines while increasing testers. In maize, methods include detasseling and controlled pollination, while canola employs male sterility with pollinator arrangements.
