Prediction of Topcross Performance from Inbred Performance in Poultry ,

Poultry Science, 1967
Abstract INTRODUCTION TOPCROSSING is one method considered by poultry breeders as a tool to evaluate the general combining ability of inbred lines. Topcrossing is defined here as the mating of males of an inbred line to females from a non-inbred tester line. This method has been studied in corn breeding (Jenkins and Brunson, 1932).

De novo assembly of transcriptomes from a B73 maize line introgressed with a QTL for resistance to gray leaf spot disease reveals a candidate allele of a lectin receptor-like kinase [PDF]

, 2020
Gray leaf spot (GLS) disease in maize, caused by the fungus Cercospora zeina, is a threat to maize production globally. Understanding the molecular basis for quantitative resistance to GLS is therefore important for food security.

Effect of full‐sib and S2‐selection on a sweet corn population (Zea mays convar. saccharata)

Plant Breeding, Volume 143, Issue 3, Page 385-402, June 2024.
Abstract Sweet corn breeding goals differ from grain or silage corn. Sweet corn goals focus on marketable yield including several quality traits. This study explores the effect of a single cycle of full‐sib selection and S2 selection on improving the marketable yield of an open‐pollinated sweet corn population.

Severe storm damage and short‐term weather stresses on corn: A review

Crop Science, Volume 64, Issue 3, Page 1129-1166, May/June 2024.
Abstract Adverse weather conditions from acute events (e.g., storms causing lodging, flooding, or hail) or short‐duration weather patterns (i.e., periods of cold events; extended waterlogged field conditions) can result in yield losses, though management practices may play key roles in aiding with crop recovery or avoidance of these stress events. This

Architectural ideotype of pear seedling in five hybrid combinations

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 1998
The architectural ideotype - type of growing - was studied in a topcross experiment with five hybrid combinations in which Cluj 72-2-100 selection, typical spur, was used as a maternal tester. The analyzed seedlings were at the end of their sixth year of

Deciphering temporal growth patterns in maize: integrative modeling of phenotype dynamics and underlying genomic variations

New Phytologist, Volume 242, Issue 1, Page 121-136, April 2024.
Summary Quantifying the temporal or longitudinal growth dynamics of crops in diverse environmental conditions is crucial for understanding plant development, requiring further modeling techniques. In this study, we analyzed the growth patterns of two different maize (Zea mays L.) populations using high‐throughput phenotyping with a maize population ...

Approaching 25 years of progress towards Fusarium head blight resistance in southern soft red winter wheat (Triticum aestivum L.)

Plant Breeding, Volume 143, Issue 1, Page 66-81, February 2024.
Abstract Tremendous progress has been made in variety development and host plant resistance to mitigate the impact of Fusarium head blight (FHB) since the disease manifested in the southeastern United States in the early 2000s. Much of this improvement was made possible through the establishment of and recurring support from the US Wheat & Barley Scab ...

AGRONOMIC PERFORMANCE AND HETEROSIS OF STRAWBERRY INBRED HYBRIDS OBTAINED BY TOP-CROSS MATING SYSTEM

Acta Scientiarum Polonorum: Hortorum Cultus, 2019
The aim of this study was to develop an inbred lines from octoploid strawberry and to determine their breeding value by estimating the effects of general combining ability (GCA) and mid-parent heterosis.
