Genome-wide association study reveals genetic architecture of coleoptile length in wheat
Theoretical and Applied Genetics, 2016Eight QTL for coleoptile length were identified in a genome-wide association study on a set of 893 wheat accessions, four of which are novel loci. Wheat cultivars with long coleoptiles are preferred in wheat-growing regions where deep planting is practiced.

The Relation of Coleoptile Length to Yield in Oats1
Agronomy Journal, 1925The work reported in this paper is a study of the relation between coleoptile length and yield from the seed of 206 individual plant selections of the Early Champion variety of oats. The correlation coefficients obtained are as follows: between uncorrected coleoptile length and uncorrected yield, 0.37 +/- 0.04; between corrected coleoptile length and ...

Coleoptile length is often associated with fall stand establishment in winter wheat (Triticum aestivum L.). While coleoptile length evaluation and improvement is a common objective of wheat breeding programs, little information is presently available to guide effective evaluation efforts.

Response to selection, combining ability and heritability of coleoptile length in winter wheat
Euphytica, 2008Selection of winter wheat cultivars with long coleoptiles is an important component of improving emergence, weed suppression and grain yield in low rainfall regions of the world. Seven winter wheat cultivars were hybridized in a Griffing’s half-diallel mating design, method 2 (reciprocals excluded, parents included), model 1 (fixed), and the progeny ...

The inheritance of crown depth was determined by measurement of subcrown‐internode length in a winter wheat (Triticum aestivum L.) cross between the semidwarf selection C.I. 13253 (‘Norin lO’/Brevor 14) and the standard height cultivar ‘Brevor.’ Cultivars and selections that form deep crowns have been reported to show less winter injury.

AbstractRice (Oryza sativa L.) seeds can germinate under anoxia and can show coleoptile elongation. The anoxic coleoptile is usually longer than aerobic coleoptiles. Although several hypotheses have been proposed to explain the ability of rice to elongate coleoptiles under anoxia, conclusive experimental evidence explaining this physiological trait is ...

Inheritance of Coleoptile Length and Culm Length in Crosses Involving Olesen's Dwarf Spring Wheat1
Crop Science, 1973Coleoptile length and culm length inheritance were studied in F1 and F3 populations from spring wheat (Triticum aestivum L.) crosses involving ‘Olesen's Dwarf’ and five tall cultivars with relatively long coleoptiles. In F2 populations studied both characters were quantitatively inherited.

Effect of selection for coleoptile length in rye, Secale cereale L.
Euphytica, 1974Two hundred and forty seedlings from each of three diverse populations were measured for coleoptile length. Significant differences between populations were found for mean coleoptile length. Considerable variability was obtained within each population with coefficient of variation values ranging from 32 to 42%. Forty seedlings from each population were

The dependence of elongation on the osmotic potential of the medium was investigated, using coleoptile segments (CS) of Triticim aestivum L. (cv. Hartri) and an optoelectronic device. The study aimed at separating the osmoelastic response from the irreversible growth response when an osmoticum (mannitol) was added, and to compare both processes in ...

Seedling Root and Coleoptile Length as Selection Criteria for Field Emergence in Pearl Millet
Journal of Sustainable Agriculture, 2001ABSTRACT Pearl millet (Pennisetum glaucum [L.] R. Br.) production in semi-arid regions is limited by poor seedling emergence that results in poor stand establishment and, low yield. Six pearl millet populations were created by divergent selection within the Tift #2 S-1 (TIFT2) pearl millet population for seedling root length in sand in the greenhouse ...
