Variety Description

Variety used for comparison: 'PH1CJB'

Summary: Including the tassel, the plants of 'PH41F0' are shorter than those of 'PH1CJB'. The leaf blade just above the upper ear of 'PH41F0' is wider than that of 'PH1CJB'. The leaf blade of 'PH41F0' has a medium degree of undulation of the margin whereas the leaf blade of 'PH1CJB' has absent or very weak undulation of the margin. The tassel of 'PH41F0' has a medium density of spikelets whereas that of 'PH1CJB' has moderately sparse spikelets. In the middle third of the main branch of the tassel, the anthers of 'PH41F0' have strong intensity of anthocyanin colouration whereas those of 'PH1CJB' have a weak intensity of anthocyanin colouration. The ear wings for 'PH41F0' are present on a low percentage of plant whereas for 'PH1CJB' they are present on a high percentage of plants. The glumes of the cob of 'PH41F0' have a medium intensity of anthocyanin colouration whereas those of 'PH1CJB' have weak intensity of anthocyanin colouration.

LATERAL BRANCHES: none
GLUME: absent or very weak intensity of anthocyanin colouration throughout
ANTHER (ON MIDDLE THIRD OF MAIN BRANCH OF TASSEL): strong intensity of anthocyanin colouration

EAR: absent or very weak intensity of anthocyanin colouration of silks, medium length husk (extends one quarter length of ear above tip), conico-cylindrical shape, medium number of rows of grain, medium intensity of anthocyanin colouration on glumes of cob

KERNEL: dent-like type, yellow on top, yellow orange on dorsal side

TILLERING: none

Origin & Breeding History: 'PH41F0' was developed by Pioneer Hi-Bred International, Inc. using a double haploid plant breeding method. In 2009, a cross was conducted between proprietary inbred lines in Puerto Vallarta, Mexico. In 2010, the F1 generation underwent the haploidization process with subsequent chromosome doubling and selfing. In 2011, selected D1 lines were self pollinated and harvested in bulk. In 2013 and 2014, the D2 and D3 lines were self-pollinated with subsequent ear selections, respectively. 'PH41F0' was selected based on tassel size, pollen production, germination ability, stalk lodging resistance, late season plant health, yield in hybrid combination, grain quality, as well as disease and insect resistance. The D5 seed was bulked as breeder seed in Garden City, Kansas, USA, in 2015.

Tests & Trials: The comparative trial for 'PH41F0' was conducted in Coteau-du-Lac, Quebec during the 2021 growing season. The trial was planted in a RCB design with 3 replicates. Each replicate consisted of one 3 metre long row with 76 cm between the rows. With approximately 20 plants per row, there was a total of 50 to 60 plants per variety. Measured characteristics were based on a minimum of 29 measurements per variety. Mean differences were significant at the 5% probability level based on paired Student's T-tests. Results were supported by the official technical examination report 201900143, purchased from the Plant Variety Protection Office in Washington, District of Columbia, USA.
