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.

Relationship between cultivar height and severity of Fusarium ear blight in wheat [PDF]
Plant Pathology, 1999 A significant negative relationship between tiller height and resistance to Fusarium ear blight (FEB), following inoculation, was observed in 17 cultivars of winter wheat in the 1995/96 growing season. Tall cultivars such as Kraka and Spark showed fewer symptoms of FEB (6 and 4%) than the shorter cultivars Brigadier and Virtue (35 ...

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 ...

Effect of cup geometry on ear height and thickening in cylindrical flatbottomed steel cups
Metals Technology, 1975AbstractAn investigation of the effect of cup geometry on ear height and wall thickening in cylindrical flat-bottom cups made from various mild steels has been carried out, and empirical relationships relating these factors have been established. The work has shown that, with reasonable accuracy, the ear height E is given by:E=MP (B2–P2/P)(B–P/P)1 ...

Evaluation of Four Testers of Different Ear Heights of Corn1
Agronomy Journal, 1960SynopsisFour single‐cross testers of different ear heights were about equally effective for measuring either ear height or yield of corn. A slight advantage was indicated for the two lowest yielding testers for yield evaluation.
