Topcross hybrids in papaya (Carica papaya L.): evaluation of the potential for increasing fruit quality in new cultivars

Archives of Agronomy and Soil Science, 2021
Multivariate analyzes such as selection indexes are one of the ways to select superior papaya genotypes with adequate quality to the consumer market, becoming more efficient after inferences made in the population from the estimate of genetic parameters.

TopCross High-Oil Corn Production

Agronomy Journal, 2002
The TopCross grain production system is rapidly gaining popularity as the preferred method of producing high‐oil corn (Zea mays L.). A blend (TC Blend) of two types of corn is planted to produce TopCross high‐oil corn (HOC) grain. Limited information is available on the effects of the TopCross system on agronomic traits that may determine the ...

TopCross High Oil Corn Production

Agronomy Journal, 2003
High oil corn (Zea mays L.) enhances the feed rations of livestock and poultry and reduces the need for expensive dietary supplements. The TopCross1 grain production system, which involves use of a blend (TC Blend) of two types of corn, is rapidly gaining popularity as the preferred method of producing high oil corn (HOC). Field experiments and on‐farm

Field Drying of TopCross High‐Oil Corn Grain

Agronomy Journal, 2001
Most high‐oil (HO) corn (Zea mays L.) grown in the USA utilizes the TopCross system, which involves planting a blend (TC Blend) of two types of corn. Field grain drying of TC Blends may be slower than normal (low oil) corn hybrids of similar maturity, which could result in later harvest or increased costs of artificial drying after harvest.

Amino acid composition of TopCross high-oil maize grain

Plant Genetic Resources, 2003
AbstractIncreased amino acid content in high-oil maize (Zea mays L.) grain may add further value to its use in livestock rations, especially if this enhanced amino acid content is consistent across varying growing conditions. Most high-oil maize (HOM) grown in the USA utilizes the TopCross system which involves planting a blend (TC Blend) of two types ...

Characterization of topcross progenies from Hereford, Limousin, and Piedmontese sires.

Journal of Animal Science, 2001
Breeds of larger mature size tend to grow more rapidly and be older when attaining a given level of fatness. Hereford, Limousin, and Piedmontese are of approximately equal mature size and yet may vary in body composition at a given degree of maturity. However, direct comparisons among these three breeds were not found.

Heterotic Effects in Topcrosses of Modern and Obsolete Cotton Cultivars

Crop Science, 2008
Historically, reselection, pedigree, and mass‐selection breeding methods have been used to develop open‐pollinated cultivars of upland cotton (Gossypium hirsutum L.). As a result, modern cotton cultivars should have accumulated additive genetic effects with time, while also possessing fewer nonadditive gene effects than obsolete cultivars.

Defoliation Affects Grain Yield, Protein, and Oil of TopCross High‐Oil Corn

Crop Management, 2003
The TopCross grain production system, in which about 90 percent of the plants in a corn (Zea mays L.) field are male‐sterile and the remainder serves to transmit the high‐oil character through pollen, is widely used to produce high‐oil corn (HOC). In the TopCross system, two types of corn are planted as a physical mixture (a TC Blend).
