Narrative

Bulk amount from SeedMark of South Australian provenance. Grown 2004. Morbulk derives from an accession of Trifolium resupinatum L. var. majus, CPI 27377-2, originally collected in Sialhot, Afghanistan in 1935, and subsequently used at the Estacao Agronomica Nacional in Portugal in the development of the cv. Maral. The development of Morbulk was the result of a screening and selection program by Agriculture Victoria which sought a suitable cultivar with reliable herbage production. The common cultivar available in Australia, Maral, is an uncertified cultivar that varies considerably depending on the origin of the seed (Kenny and Reed 1985; Lee and Reed 1993). The high feeding value and various roles of Persian clover in southern Australia have been outlined by Kenny and Reed (1984), Flinn et al.(1985) and Stockdale (1993). Persian clover can be cut for hay or grazed as standing hay. It shows excellent regrowth after cutting or grazing. Persian clover grows well under waterlogging and mild salinity and has a broad range of pH tolerance (pH 5.0-8.5). Morbulk has similar digestibility and crude protein levels to Maral but is 10 days earlier in maturity. It is at least as productive as Maral in late spring and 36% more productive, on average, in winter and early spring. It can be grazed in late winter-early spring and then cut for hay in late spring-early summer. During the 1995 season, in spring cuts taken at 4 sites, Morbulk outyielded Maral by 23% (Clark et al. 1996; Evans and Cameron 1998). Morbulk has the potential to replace Maral and extend the use of Persian clover into areas with lower rainfall (i.e between 500 and 800 mm/year). Morbulk is grown as an annual crop from seed inoculated with Persian clover inoculant, rhizobial strain No. CC2483g. Morbulk has produced 68% more seed than Maral at Hamilton on 1 occasion and has the ability to grow well in mildly saline conditions (Clark et al. 1996). The accession from which Morbulk was selected has been characterised as resistant to clover scorch [Kabatiella caulivora (Kirchn.). Karak] disease (Snowball 1993). The reaction of Morbulk to rust was not significantly different to that of Maral.
