With 2 figures and 4 tablesAbstractThe magnitude of genotypic correlations between family per se and testcross, r^g (per se, TC), is crucial for testing schemes in hybrid breeding as well as improvement of commercial hybrids. The objectives of this study were to identify the r^g (per se, TC), to examine the proportion of common QTL for both types of ...

Selection for Grain Yield following Selection for Ear Height in Maize
Crop Science, 1993Recurrent selection improves population performance by increasing the frequency of favorable alleles. In maize (Zea mays L.), the higher frequency of favorable alleles in a population is expected to result in improved performance of inbred lines and hybrids derived from the population.

Quantitative trait loci for flowering, plant and ear height, and kernel traits in maize
Crop Science, 1995The inheritance of quantitative traits is not well understood. A study was conducted to determine the number and chromosomal locations of quantitative trait loci (QTL) controlling male anthesis date; plant and ear height; kernel weight; and kernel protein, oil, and starch concentration in maize (Zea mays L.).

With 2 figures and 5 tables Abstract Two populations, one comprising 98 near-isogenic introgression lines (Z3HBILs) with a Zong3 genetic background, and the other comprising a backcross population developed by crossing introgression lines per se with Zong3, were employed to identify quantitative trait loci (QTL) for plant height and ear ...

Diallel Analysis of Ear Height and Associated Characters in Corn 1
Crop Science, 1978Early and late low ear corn (Zea mays L.) synthetics were developed by sib‐mating for lower ear height over 12 cycles of selection. Cycles 1, 3, 5, 7, 8, 9, and 10 were crossed in a diallel set for a study on inheritance of ear height and associated characters.Ear height was reduced an average of 3.20 cm per cycle in the early synthetic and 2.98 cm in ...

Ear Height and Weight as Related to Stalk Lodging in Maize 1
Crop Science, 1984Measurements of ear height, ear weight, and a potential torque index were made on individual plants jointly chosen from within 972 hills of maize (Zea mays L.). A stalk lodged and unbroken plant in each hill were measured. Plants were classified as stalk lodged or unbroken plants whether or not they were root lodged.

Plant‐to‐plant reciprocal crosses were made between the maize (Zea mays L.) strain Illinois High Oil (IHO) and each of seven maize inbreds plus the strain Illinois Low Oil (ILO). Oil analysis showed that the direction of the cross caused the oil content of F1 kernels to vary an average of 3.00%. Paternal effects were of similar magnitude. These effects

Effects of selection for lower ear height in synthetic populations of maize.
Crop Science, 1970Two populations of maize (Zea mays L.) [Antigua 2D ✕ (B10 ✕ B14)] F5 and (Eto ✕ CBC) F5 were used a selection experiment conducted at Lafayette, Ind., to determine the effectiveness of 50% selection intensity in lowering ear height. These two populations were subjected to two cycles of selection, each followed by a generation of random intermating in ...

Drought is a major abiotic stress reducing maize yield worldwide especially before and during silking. The mechanism underlying drought tolerance in maize has not been elucidated especially from the perspective of different organs.
