Confirming QTL for seed yield from exotic soybean germplasm
… contribute both genetic diversity and improved seed yield potential in the N.A. gene pool. Of the putative QTL for seed yield that have been identified, only a small percentage have been tested in confirmation trials and even fewer have been confirmed. The objective of this study is to confirm …

Effect of plant density on soybean seed yield and quality
… of plant density on the growth, development, seed yield and seed quality of soybean (Glycine max [L.] Merrill) were investigated in the 2001/2002 season on a Wakanui silt loam soil at Lincoln University, Canterbury. Seeds of two cultivars, Northern Conquest and March were hand sown on 1 …

Factors influencing seed yield and quality of dwarf French bean (Phaseolus vulgaris L.) in Canterbury
Treatments designed to influence seed quality were imposed on dwarf French bean plants during crop development and maturation. The effects of the treatments on seed yield and yield components, as well as the suitability of Canterbury for growing this crop as a seed crop, were determined. In 1996/97 …

Growth Parameters and Their Use in Predicting Seed Yield in Soybeans (seed-Filling Period, Glycine Max)
… has demonstrated a positive relationship between seed-filling period (SFP) and seed yield in soybean Glycine max (L.) Merrill . Two studies were conducted to (1) predict the gain in seed yield by selection for SFP and (2) to determine which growth parameters are most important to seed yield among …

Soybean seed yield and size as influenced by row spacing and seeding rate and seed-size heritability
Soybeans within a specific seed size range are often preferred for the manufacture of specialty soy products. This study examined the influence of row spacing and seeding rate on seed yield, average seed size, and seed size uniformity of Camp (small seeded) and V71-370 (large seeded) soybean …

Studies on Plant Height and Flowering Date and Their Effect on Seed Yield in Determinate Soybeans (Glycine Max)
… Merr. in the northern U.S. because of their yielding ability and lodging resistance. Two experiments were conducted to (1) estimate the heritability of days to flowering (R1) and maturity (R8), and plant height at these two stages; (2) evaluate the relationships among the traits; and (3) …

Double-Crop Soybean Vegetative Growth, Seed Yield, and Yield Component Response to Agronomic Inputs in the Mid-Atlantic, USA
… in the Mid-Atlantic, USA. Reduced double-crop yield can be attributed to: delayed planting that results in a shortened growing season and less vegetative growth; later-maturing cultivars that terminate main stem growth after flowering and have less growth and nodes; less soil moisture and …

Phenotyping Canola (Brassica napus L.) Agronomic Traits and Estimating Seed Yield Using Unoccupied Aerial Vehicle (UAV)-based Multispectral Imagery
Canola (Brassica napus L.), as an important oilseed crop, is widely grown in Canada. In plant breeding, there has been great improvement in genetic techniques, but traditional field phenotyping methods are a limitation in breeding genotype selection for new cultivar development. These conventional …

Inheritance of Cold Temperature Emergence in Soybeans and Its Relationship to Field Emergence and Seed Yield of Early Planted Soybeans (Heritability, Genetic, Vigor)
… can result in decreased emergence, reduced seedling vigor, increased incidence of disease, and lowered yields. Soybean genotypes with superior cold temperature emergence (CTE) ability will avoid these problems.

Management and Interference Potential of Common Waterhemp (Amaranthus Rudis) in Soybean (Glycine Max)
… period soybean could tolerate without reducing seed yield. Removal of common waterhemp interference 2 weeks after soybean unifoliolate expansion resulted in soybean seed yield equivalent to a season-long weed free control, but delaying common waterhemp removal longer than 2 weeks resulted in …

Crop manipulation to improve hybrid radish seed yield and quality : A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy at Lincoln University
Hybrid radish (Raphanus sativus L.) seed is grown in New Zealand for multiplication and re-export, and radish seed exports were worth $22.8 million in 2017. Seed yields vary with hybrid and season, but are reduced by lodging, which reduces seed filling, increases disease problems, and causes …

Effect of applied B, Cu, Mn and Zn on soybean yield and micronutrient concentration
The effect of applied B, Cu, Mn and Zn on soybean seed yield and tissue micronutrient concentration was studied under different field conditions. Manganese application increased soybean seed yield on the Dragston, Myatt and Slagle fine sandy loams, but not on Rains fine sandy loam. Seed yield was …
