Systematic genetic advance in maize ( Zea mays L.) hybrid yields depends on the improvement of breeding populations and efficient extraction inbred lines. We evaluated efficacy selection among within fullsib families produced two 2‐eared for lines identification superior yielding hybrids. Intra‐ interpopulation crosses were made selected unselected developed from ‘Iowa Two‐ear Synthetic’ (BSI0) ‘Pioneer Prolific Composite’ (BSll). The paired‐plant tested S 0 ✕ through 4 generations. Six...
Abstract Corn ( Zea mays L.) yields have increased in the United States since 1930s and other parts of world 1950s 1960s because improvements agricultural management genotypes. Despite these increases, production concerns still exist. In July 2016, abnormal ear development (multi‐ears per node, barbell‐ears, short‐husks) was reported cornfields that extended from Texas Panhandle to eastern Colorado east through Kansas, Nebraska, Iowa, Illinois. Surveys Nebraska farmer fields revealed...
A common hypothesis among farmers is that there are unique crop traits necessary to achieve high yields in organic systems not currently expressed conventionally developed cultivars. To test this hypothesis, high-yielding cultivars of three annual crops conventional were grown parallel and cropping over multiple years. Yield results revealed no consistent genotype by system interactions. We conclude with it logical choose the highest yielding genotypes based on nonbiased yield comparison...
Corn plants were sampled over 2 consecutive years to assess the effects of corn hybrid maturity class, plant population, and harvest time on whole quality yield in Nebraska. A finishing experiment evaluated substitution with silage diets modified distillers grains solubles (MDGS). The first dates at mid- late-silage times whereas final was grain stage maturity. Whole yields increased as progressed (yr 1 quadratic P < 0.01; yr linear 0.01). However, differences TDN concentration both quite...
Abstract In July of 2016, abnormal ear development in corn ( Zea mays L.) (barbell‐ears, multiple ears per node herein termed as multi‐ears, and short‐husks) was reported several cornfields that extended from the Texas Panhandle to eastern Colorado East through Kansas, Nebraska, Iowa, Illinois. Field surveys were conducted study these abnormalities. Affected unaffected plants sampled 15 farmer fields located central Nebraska. Each plant evaluated for type, placement, internode length, grain...
