Variety Description

Varieties used for comparison: '92M61' and 'PS2314NR2'

Summary: When 50% of the pods are ripe, the plants of 'P24T19R' are shorter than those of both reference varieties. The seed shape of 'P24T19R' is spherical whereas it is spherical flattened for both reference varieties. The hilum colour of 'P24T19R' is light brown whereas it is imperfect black on 'PS2314NR2'. 'P24T19R' is later maturing than 'PS2314NR2'.

HYPOCOTYL: strong intensity of anthocyanin colouration

LEAF: pointed ovate lateral leaflet

FLOWER: violet

POD: medium to dark brown colour
SEED: spherical shape, yellow ground colour of testa, 17.5 grams per 100 seed at 13-15 % moisture
HILUM: light brown, yellow funicle

AGRONOMICS: 3125 heat unit rating

QUALITY CHARACTERISTICS: 39.5 % protein, 22.8 % oil

Origin & Breeding History: 'P24T19R' (experimental designations 'XB25E12' and 'PH12204') is the result of the cross between '92Y30' and 'RJS25003' conducted in 2006 in Viluco, Chile. The modified single seed descent method and pedigree method were used to develop the variety. The F1-F2 generations were grown in Salinas, Puerto Rico and the F4 generation was grown in Viluco, Chile. The F3 and F5 generations grown in Cedar Falls, Iowa, USA were advanced based on yield for single plants and progeny rows. Single plant purification took place in 2009 in Cedar Falls, Iowa. Wide area testing continued from 2010-2012 in the USA and Canada. Selection criteria included yield, maturity and resistance to Roundup branded herbicides, to Phytophthora rot (Phytophthora megasperma f. sp. glycinea) and to soybean cyst nematodes (Heterodera glycines).

Tests & Trials: The comparative trial for 'P24T19R' conducted in Chatham, Ontario during the 2013 growing season was planted in a RCB design and consisted of 3 replicates for each variety. Plots consisted of 2 rows 4 metres in length and a row spacing of 76 cm. Each plot was sown with 300 seeds per replication. For each variety, the plant height was based on 30 measurements whereas the seed weight was based on 3 measurements. Mean differences were significant at the 5% probability level based on LSD values. Results were supported by the official technical examination report 201200197, purchased from the Plant Variety Protection Office, Beltsville, Maryland, USA.
