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...
متن کاملMeiotic 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...
متن کاملBreeding 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...
متن کاملLeaf Transpiration Effi ciency of Sweet Corn Varieties from Three Eras of Breeding
When measured under midday fi eld conditions, modern varieties of maize (Zea mays L.) often have substomatal carbon dioxide concentration (Ci) values in excess of those required to saturate the photosynthetic carbon dioxide assimilation rate (A). This results in lower leaf transpiration effi ciency (TE), the ratio of photosynthesis to transpiration, than potentially achievable for a given rate ...
متن کاملPLANT RESISTANCE Evaluation of Conventional Resistance to European Corn Borer (Lepidoptera: Crambidae) and Western Corn Rootworm (Coleoptera: Chrysomelidae) in Experimental Maize Lines Developed from a Backcross Breeding Program
Plant resistance is a promising control method for the two most damaging insect pests of maize, Zea mays L.: the European corn borer, Ostrinia nubilalis (Hübner), and the western corn rootworm, Diabrotica virgifera virgifera LeConte. Fifteen experimental lines of maize, derived from a backcross breeding program designed to introgress resistance to European corn borer from Peruvian maize into tw...
