Registration of ‘Reveille’ Hybrid Bluegrass

Development of ent-kaurene Oxidase-Based Conserved Intron Spanning Primers for Species Identification in the Genus Poa (Poaceae; Bluegrass)

“…This primer pair amplified two bands from each species, where one of the bands was polymorphic and the other was monomorphic (Figure 2). Texas bluegrass hybrid 'Reveille' is a released cultivar from a cross between P. arachnifera TAES 6012 and P. pratensis 'Huntsville' [4]. When the primer pair TxKy-F /TxKy-R was run on the parents and the F 1 Reveille, the upper monomorphic band and two lower polymorphic bands from each parent were amplified in Reveille (Figure 2).…”

“…Texas bluegrass hybrid 'Reveille' is a released cultivar from a cross between P. arachnifera TAES 6012 and P. pratensis 'Huntsville' [4]. Based on the KO sequences, the primer pair TxKy-F/TxKy-R should have produced a single band in P. pratensis that was intermediate to the two P. arachnifera bands (Table 1).…”

“…Kentucky bluegrass (Poa pratensis L.) is one of the primary cool-season turf species used on home lawns and sports fields because of its excellent turf quality and its ability to reproduce through apomixis [2]. The hybridization of Texas bluegrass and Kentucky bluegrass can bring together the traits of heat and drought tolerance with increased turf quality and apomixis [3][4][5]. More recently, Canada bluegrass (Poa compressa L.), Poa ligularis (Nees ex Steud.…”

Genetic Relationships in Advanced Generation Hybrids Derived from Crosses between Texas (<i>Poa arachnifera</i>) and Kentucky (<i>Poa pratensis</i>) Bluegrass Using ISSR Markers

“…is a highly rhizomatous, dioecious, perennial cool-season grass native to southern Kansas, Oklahoma, western Arkansas and most of Texas [1]. Interspecific hybrids with Kentucky bluegrass (Poa pratensis L.) have the potential to produce low-input turf type plants with greater heat and drought tolerance [2,3]. Assuming this grass will be propagated by seed, a Texas × Kentucky (TK) hybrid needs to inherit a Kentucky like inflorescence containing both male and female structures with the ability to self-pollinate and produce seed via apomixis.…”

“…The cottony seed characteristic of the female Texas parent must also be drastically reduced or eliminated to enable combine harvesting and commercial-type seed cleaning for a hybrid to be accepted by the turf industry. Reveille [3] hybrid bluegrass is the only cultivar documented in the literature and is a first generation (F 1 ) hybrid. Over the last 10 years, many Texas × Kentucky hybrids have been created and confirmed visually and by DNA fingerprinting with the same methods described by Goldman and Sims [4] and Goldman [5].…”
