AGRONOMY:fair to good lodging resistance
QUALITY: very low erucic acid levels, low glucosinolates
Origin & Breeding History: '65037' is a conventional restorer line that could be used with herbicide tolerant females to create herbicide tolerant hybrids, derived via pedigree breeding by the breeder, Zenon Lisieczko, from a cross made in 1996 between two proprietary Monsanto lines '65013' and 'Surpass 400'. '65037' was selected for general combining ability for yield and quality, short height plus moderate resistance to blackleg.
Tests & Trials: Tests and trials for '65037' were conducted during the summers of 2005 and 2006 at the Elora Research Station, Elora, Ontario. Plots consisted of 4 rows which were 5 meters in length and a row spacing of 35 cm. There were 2 replicates arranged in a Random Complete Block Design.
