“…The breeding pedigree of this line before the ID designation of PS‐592 is obscure because a large seed increase was accomplished in an isolated, noninfested FOV4 field at the University of California Kearney Research and Extension Center, Parlier, CA, in which Pima S‐6 and Pima S‐7 germplasm were included in the same field. Outcrossing in cotton ranged from 0.5 to 10%, depending on insect pressure and bee activity for the most part (Loureiro et al., 2016; Van Deynze et al., 2011). Mass selection was applied toward selection of columnar growth and fruiting cluster habit genotypes, and open pollinated bolls were harvested from single plants in 2009.…”

Over the past 18 yr, Fusarium wilt race 4 (FOV4) has affected cotton (Gossypium spp.) production in the San Joaquin Valley of California, and more recently this pathogen was formally identified in 2017 in the El Paso, TX, region and in 2019 in New Mexico. The primary purpose for the germplasm release is to provide cotton breeders with needed alternative sources for continuing to improve FOV4 resistance in pima cotton. PSSJ-FRP01 (Reg. no. GP-1107, PI 699963) (PS-592) originated from Pima S-6 × G. barbadense pool accessions GB1368/k-7616. Pima S-6 possesses a major gene(s) for FOV4 resistance. GB1368/k-7616 is Uzbekistan accession introduction with different plant structure, large leaves, columnar growth, and a more clustered fruiting habit when compared to most American pima. PSSJ-FRP02 (Reg. no. GP-1108, PI 699964) and PSSJ-FRP03 (Reg. no. GP-1109, PI 699965) originated from PS-592 × SA-3208 (LIAO MIAN 7 HAO). SA-3208 is moderately resistant to FOV4. Multiple selections and recurrent cycles of selections were applied to these new germplasm lines based on an asymptomatic single plant after greenhouse FOV4 inoculations and/or infested field evaluations from F 1 to F 4 . In subsequent field and greenhouse tests in 2019-2021, the germplasm lines showed improved resistance to FOV4 based on low percentage mortality and vascular staining and fiber quality when compared to commercial cultivars. PSSJ-FRP01, PSSJ-FRP02, and PSSJ-FRP03 lines will help to continue reducing the vulnerability of the pima cotton industry to this fungal pathogen and to advance efforts to broaden the genetic base of FOV4 resistance, which is critical to the pima cotton industry in the United States and Uzbekistan.

“…Studies with corn, wheat, rice and canola demonstrated that, depending on the crop, a distance of 20 to 50 m was sufficient to keep the fraction of GM plants below 0.9%. Nevertheless, presence of transgenes below 0.9% was detectable up to a maximum distance of 350 m [4] , [5] , [6] , [7] , [8] . In addition to unintended admixture with non-transgenic crops, the potential introgression of GM plants into wild relatives is discussed, particularly when the transgene might increase the plant fitness or competitiveness [9] , [10] , [11] , [12] .…”

“…Isolation distances to manage cross-fertilisation between GM and non-GM variants of the same species differ with species, 356 from 5 to 10m for soybean, 357 about 10m for cotton, 358 , 359 20 to 50m for maize, 360 , 361 about 100m for Lolium rigidum , 362 tall fescue ( Festuca arundinacea ) at 150m, 363 30 to 200m for canola, 364 , 365 and 150 to 500m for lucerne. 366 Pollen-mediated gene flow was measured in the Netherlands through growing the maize variety DKC3421YG containing the MON810 GM event at 25m (the distance indicated as required between GM crops and conventional crops) or 250m (the distance indicated as required between GM-crops and organic crops) from a near-isogenic non- GM cultivar.…”

Innovation in agriculture has been essential in improving productivity of crops and forages to support a growing population, improving living standards while contributing toward maintaining environment integrity, human health, and wellbeing through provision of more nutritious, varied, and abundant food sources. A crucial part of that innovation has involved a range of techniques for both expanding and exploiting the genetic potential of plants. However, some techniques used for generating new variation for plant breeders to exploit are deemed higher risk than others despite end products of both processes at times being for all intents and purposes identical for the benefits they provide. As a result, public concerns often triggered by poor communication from innovators, resulting in mistrust and suspicion has, in turn, caused the development of a range of regulatory systems. The logic and motivations for modes of regulation used are reviewed and how the benefits from use of these technologies can be delivered more efficiently and effectively is discussed.
