Registration of 'DALSA 0605' St. Augustinegrass Academic Article uri icon


  • Crop Science Society of America. All rights reserved. DALSA 0605 (Reg. No. CV-274, PI 671959) is an embryo rescue-derived interploid hybrid of St. Augustinegrass [Stenotaphrum secundatum (Walt.) Kuntze] resulting from a cross between TAES 5382 (African triploid PI 291594) and Palmetto (diploid). DALSA 0605 was evaluated under the designation TAES 5471-18 and TXSA 19 and was approved for release as a new cultivar by Texas A&M AgriLife in 2014. DALSA 0605 is a vegetatively propagated, genetically stable, and uniform cultivar. It is distinguished from other cultivars of St. Augustinegrass for traits and characteristics that include (i) tolerance to gray leaf spot disease (caused by Magnaporthe grisea Couch), (ii) significantly reduced levels of fecundity and juvenile development of southern chinch bugs (Blissus insularis Barber) as compared to Raleigh and Texas Common, and (iii) superior drought resistance conferred through a combination of tolerance to drying soil, deep rooting potential, and rapid recovery following drought. In addition, DALSA 0605 exhibited percentage rates of establishment and turfgrass quality ratings (normal and drought-stress conditions) comparable to commercial checks in multilocation (seven) and multiyear (two) field evaluations. DALSA 0605 is well suited for use on residential and commercial lawns, as well as other recreational sites, throughout the southern and southeastern United States.
