QTL mapping analysis of plant height and ear height of maize (Zea mays L.).
Genetika, 2006Genetic map containing 103 microsatellite loci obtained on 200 F2 plants derived from the cross R15 x 478 was used for quantitative trait loci (QTL) mapping in maize. QTL were characterized in a population of 200 F2:4 lines, derived from selfing the F2 plants, and were evaluated with two replications in two environments.

Acta Agronomica Hungarica, 2002
The plant height and the height of the main ear were studied over two years in twelve single cross maize hybrids sown at three different plant densities (45, 65 and 85 thousand plants/ha) at five locations in Hungary (Keszthely, Gönc, Gyöngyös, Sopronhorpács, Martonvásár).

Further Selection for Lower Ear Height in Maize1
Crop Science, 1972The effectiveness of selection for lower ear height and the associated responses of four agronomic traits were evaluated. In a previous study two populations of maize (Zea mays L.), ‘Antigua 2D’ ✕ (BIO ✕ B14) and ‘ETO’ ✕ ‘CBC,’ were selected for lower ear height at a selection intensity of 50%. In this study they were submitted to two further cycles at

Effects of differences in date of ear emergence and height on yield of winter wheat
The Journal of Agricultural Science, 1985SUMMARYEarly and late, and short and tall lines were selected from a cross between the winter wheat varieties Norman and Talent. All short selections carried the Rht2 dwarfing gene while the tall ones did not. The selections were compared in field experiments at the Plant Breeding Institute in Trumpington and at The Murrays Experimental Farm of the ...

Plant Breeding, 2011
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 ...

[QTL mapping of plant height and ear position in maize (Zea mays L.)].
Yi chuan = Hereditas, 2009A molecular linkage map for the maize hybrid of cross between Ye478 and Dan340 was constructed by using 150 co-dominant SSR markers. The total map length was 1 478.7 cM with an average interval of 10.0 cM. Composite interval mapping was used to identify the plant height (PH) and ear position (EH) QTL at 5 environments based on the phenotypic data of ...

Diallel Analysis of Ear Height and Associated Characters in Corn1
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 ...

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.).

Ear Height and Weight as Related to Stalk Lodging in Maize1
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.

Yi chuan = Hereditas, 2009
One hundred and ninety-one F2 individuals derives from the cross, Mo17xHuangzao4, were genotyped by SSR and AFLP markers to construct the genetic linkage map, and 184 corresponding F2:3 families were phenotyped for maize (Zea mays L.) plant hright and ear height in Changping and Shunyi. A mixed linear model approach and its software were used to detect
