Commercial Corn Breeding

Breeding for Increased Sweetness in Sweet Corn

Sweetness, a creamy texture and aroma, along with desirable kernel color, good germination, and high yield, are the important traits for sweet corn. Various recessive mutants in corn expressed in the endosperm e.g. sugary1 (su1), sugary enhancer (se), shrunken2 (sh2), brittle1 (bt) etc., which improve quality traits such as sweetness, flavor and nutritive value have been used either singly or i...

Commercial conceptions: a breeding ground for surrogacy.

Meiotic behavior as a selection tool in silage corn breeding.

In breeding programs, commercial hybrids are frequently used as a source of inbred lines to obtain new hybrids. Considering that maize production is dependent on viable gametes, the selection of populations to obtain inbred lines with high meiotic stability could contribute to the formation of new silage corn hybrids adapted to specific region. We evaluated the meiotic stability of five commerc...

Breeding Maize for Drought Tolerance in the US Corn-Belt

The objective of this review is to promote discussion on some of the key issues we consider to be involved in successful long-term genetic improvement of corn for drought tolerance. Many of the concepts have been discussed elsewhere for different crops, traits and different breeding targets. Here we focus on how to organize a comprehensive effort to enable breeding for drought tolerance in a he...

THE HYDROLYSIS OF CORN-STARCH BY COMMERCIAL PAiWREATIN

The hydrolysis of potato starch by pancreatin has been the subject of much investigation, particularly by Sherman and his pupils (I), who have studied the action of both malt and pancreatic amylase upon potato starch, especially with reference to optimum concentration of enzyme, substrate, pH value, and concentration of activating salts. The best conditions of hydrolysis were at (2) 40” in the ...
