Sunflower production: Hybrids versus open pollinated varieties on dry land

Salt tolerance of sunflower varieties during germination

Genomic Prediction of Sunflower Hybrids Oil Content

Prediction of hybrid performance using incomplete factorial mating designs is widely used in breeding programs including different heterotic groups. Based on the general combining ability (GCA) of the parents, predictions are accurate only if the genetic variance resulting from the specific combining ability is small and both parents have phenotyped descendants. Genomic selection (GS) can predi...

Comparison of Open-pollinated and Hybrid Onion Varieties for New Mexico

Eighteen hybrid onion and 23 open-pollinated (OP) varieties were tested in southern New Mexico for plant characteristics, disease resistance, and bulb yield in order to determine if hybrid varieties outperformed OP varieties. Varieties were shortto intermediate-day in their bulbing response and were planted in the fall seasons of 1997 and 1998 and harvested the following May or June. Varieties ...

Corn production and plant characteristics response to N fertilization management in dry-land conventional tillage system

Nitrogen (N) application management needs to be refined for low yielding environments under dryland conditions. This 3-yr study examined nitrogen fertilization management effects on corn (Zea mays L.) plant characteristics and grain yield in rain fed environment under conventional tillage system. Nitrogen fertilization management consisted of two timing methods of N application [all N at planti...

Host Suitability of Commercial Sunflower Hybrids to Pratylenchus zeae.

Host suitability of commercial sunflower hybrids to Pratylenchus zeae was studied in the field and greenhouse. For comparison, one maize and one grain sorghum inbred line, both susceptible to P. zeae, were included in the greenhouse experiments. Pratylenchus zeae densities extracted from the roots of sunflower hybrids grown in naturally infested soil were low. In the first greenhouse experiment...
