Dib-u-fikiridda shahaadada baradhada abuurka Aragtida 2026: u dhaqaaqidda nidaam diiradda saaraya beeralayda

(FIIRO GAAR AH: Kani waa tii ugu horreysay ee taxane laba qaybood ah oo ku saabsan barnaamijka Aragtida 2026 si dib loogu eego nidaamka shahaadada baradhada abuurka.)

Adkaysiga la-taliyaha dalagga si uu u caawiyo beeralayda baradhada abuurka iyo aaminsanaanta ah in ay jirto hab dhakhso badan oo ka wanaagsan oo lagu heli karo xogta caafimaadka abuurka ayaa siisay asal qumman cilmi-baarayaasha ka socda USDA-ARS (Ithaca, New York) iyo Jaamacadda Gobolka Colorado (CSU) si ay u turjumaan shaqo shaybaar oo toban sano socotay una beddelaan isticmaalka adduunka dhabta ah. Waxaa xiiso leh, dadaalkan ay wadaan daneeyayaasha ayaa si fiican ugu biiray Aragtida Golaha Qaranka ee Baradhada 2026, oo ah koox loo xilsaaray inay aqoonsadaan oo ay isticmaalaan qalab cusub oo la heli karo si loo soo saaro baradho tayo sare leh si loo daboolo baahiyaha macaamiisha marka faa'iidada ay sii yaraanayso.  

Nidaam leh taariikh qarni ka badan 

Shahaadada baradhada abuurka ee Mareykanka waxay leedahay taariikh ilaalin ah caafimaadka baradhada abuurka tan iyo 1913. Hay'adaha shahaadada iyo cilmi-baarayaashu waxay go'aamiyeen jeermiska muhiimka ah, waxay sameeyeen baaritaanno molecular oo xasaasi ah oo loogu talagalay ku dhawaad ​​​​dhammaan jeermiska xaddidaya wax soo saarka baradhada abuurka ee Mareykanka, waxayna sameeyeen heerar muunad iyo dulqaad ku habboon oo loogu talagalay cudurrada laga qaado tubaakada. 

Current seed potato certification relies primarily on visual inspection of potato fields during the growing season followed by postharvest grow outs for detecting viruses, such as PVY. Collectively, the 16 state-level seed potato certification programs evaluate 100,000 acres in the summer and further sample over a million tubers from those fields annually to evaluate the health of seed lots in winter testing systems.

Waxaa loo baahan yahay in la hagaajiyo xaaladda hadda jirta 

Markaa, haddii wax walba diyaar yihiin, waxaa laga yaabaa in qofku uu la yaaban yahay in loo baahan yahay in dib loo eego hababka hadda jira. Hagaag, ku tiirsanaanta joogtada ah ee calaamadaha aragga lagu aqoonsan karo ayaa keentay nooc cadaadis xulasho ah oo loogu talagalay noocyada cudur-sidaha ee aan lahayn calaamadaha si fudud loo arki karo. Intaa waxaa dheer, dhaqdhaqaaqa caalamiga ah ee jeermiska ayaa mas'uul ka ah soo bandhigidda iyo faafinta cudur-sidaha kale ee soo baxaya kuwaas oo cusub ama isbeddelay tan iyo markii shahaadada abuurka la hirgeliyay markii hore. Dhowr cudur-sidaha cusub, sida fayraska baradhada ee mop-top iyo fayraska qiiqa tubaakada oo sababi kara diidmada processor-ka cilladaha gudaha, si liidata ayaa loo fahmay. Cudurradan cusub waxay muujin karaan calaamadaha caleenta si kala duwan iyadoo lagu saleynayo cimilada, nooca baradhada, iyo loolka qaarna si dhif ah ayay u keenaan calaamado caleenta ah. 

Waqtiga loogu talagalay sameynta go'aannada ganacsiga ee muhiimka ah 

Tan ugu muhiimsan, hay'adaha shahaadeynta baradhada abuurka ayaa badanaa siiya natiijooyinka shahaadeynta beeralayda afar bilood ka dib marka ay goostaan ​​​​tubooyinka. Tani waxay ku lug leedahay ururinta muunadaha digriiga, jebinta hurdada tuber-ka si kiimiko ah, rarista dhowr kun oo rodol oo digriiga ah meelaha jiilaalka laga beero sida Hawaii iyo Florida, ka qaadista caleenta geedaha canabka ah, tijaabinta ka dibna siinta natiijooyin beeralayda. Waqtigan dib u dhaca ah wuxuu xaddidayaa awoodda beeralayda baradhada abuurka iyo iibsadaha abuurka inay sameeyaan go'aanno maareyn ganacsi oo wanaagsan iyagoo sugaya natiijooyinka shahaadeynta abuurka ee go'aaminaya in iniinaha loo iibin karo sidii iniin la xaqiijiyay iyo in kale.  

Si loo bixiyo ballanqaad qof doonaya inuu iibsado baradhada abuurka, beeraleyda baradhada abuurka waa inay awoodaan inay helaan natiijooyinka shahaadaynta waqtiga ugu dhaqsaha badan. Hal dariiqo oo looga gudbi karo caqabaddan waa in la isticmaalo baaritaanka PCR (oo la mid ah baaritaanka fayraska SARS-CoV-2) ee digriiga cusub ee la goostay kaas oo hagaajin kara ogaanshaha jeermiska iyadoo la siinayo natiijooyin degdeg ah beeraleyda. 

Tani waxay macno u samaysay Don Sklarczyk, kaasoo loo xilsaaray inuu baaro baahiyaha mustaqbalka ee warshadaha sida volunteer Guddoomiyaha Guddiga Caafimaadka Baradhada ee Qaranka ee Himilada Caafimaadka Baradhada ee Aragtida 2026. Sklarczyk laftiisu, oo ah hal-abuure ku takhasusay soo saarista baradhada dhaqanka unugyada sannadihii 1980-meeyadii ee Beerta Seed ee Sklarczyk, Michigan, wuxuu ku socday xadka u dhexeeya dhaqaalaha wax soo saarka hufan iyo khatarta/faa'iidada hababka cusub, waayo-aragnimadanina waxay Don ka dhigtay doorasho cad oo uu ku isku dubarido kooxaha raadinaya siyaabo cusub oo wax loo qabto.

Siday wax waliba u bilaabeen 

Waxa ka bilaabmay shaybaarka Stewart Gray (saynisyahan hawlgab ah oo USDA-ARS ah) codsi ah "hel hab lagu baaro digriiga fayrasyada baradhada oo lagu awoodo in lagu tijaabiyo 10,000-meeyadii" tan iyo markaas waxay horumarisay nolol u gaar ah oo xiiso leh oo ka kala socota gobollo kala duwan iyo hay'adaha shahaadada bixiya. Baaritaanka tuubada ee miisaanka loo baahan yahay si loo xaqiijiyo dhul abuurka ah waxay noqon kartaa cabbir adkeysiga aadanaha sababtoo ah waxay u baahan tahay 400 oo digrii oo si aan kala sooc lahayn loo soo ururiyey si loo saadaaliyo in heerarka cudurku ay yihiin kuwo la aqbali karo oo ku yaal goobta oo dhan. 

Laakiin sidee baad u tijaabisaa digriiga kumanaan? Shaybaarka Gray wuxuu la qabsaday tignoolajiyada goobta dambiyada booliiska iyadoo la horumarinayo nooc gaar ah oo ah Kaararka FTA ee Whatman oo caan ku ah baaritaanka aadanaha. Habkan cusub wuxuu bixiyay hab ammaan ah oo lagu ururin karo, lagu qaadi karo laguna kaydin karo DNA-da baradhada heerkulka qolka. Habkani wuxuu sidoo kale meesha ka saaray baahida loo qabo in digriiga culus ee ku daboolan ciidda loo raro shaybaarrada baaritaanka. Intaa waxaa dheer, waxay sameeyeen baaritaanno molecular ah oo loogu talagalay farsamaynta baaxadda weyn waxayna ogaadeen nooca muunadda laga qaadayo tuber si loo helo fursado tirakoob oo la aqbali karo si loo go'aamiyo xaaladda caabuqa dhabta ah. Hadda oo hababka la sameeyay, tallaabada macquulka ah ee xigta waxay ahayd in hababkan lagu daro codsiyada adduunka dhabta ah. 

Gacmo badan ayaa shaqada fududeeya 

Isagoo wax ka baranaya cilmi-baarista Gray, beeraley abuurka ah oo horumarsan oo xiiseynaya inuu wax badan ka barto dalagga baradhada abuurka beertiisa oo ay weheliyaan cilmi-baarayaasha USDA-ARS iyo CSU wuxuuna u soo bandhigay beertiisa, shaqada, iyo dalagga abuurka goob tijaabo ah oo loogu talagalay iskaashiga beeraha. Bishii Oktoobar 2020, beeraleydu waxay shaqaalihiisa ku hawlan beeraha u ballan qaadeen laba maalmood oo shaqo mushahar leh si ay u sameeyaan muunad tuubbo ah - maaraynta digriiga ayaa ah mid ka mid ah caqabadaha ku hor gudban baaritaanka molecular-ka ee ku salaysan shaybaadhka. 

Shaqaalaha waxaa lagu tababaray goobta si ay muunado tuber ah ugu dhigaan kaararka FTA kuwaas oo loo diray shaybaarka USDA-ARS si loogu sameeyo falanqayn hoose halkii laga rari lahaa digriiga. Taas beddelkeeda, beeralaydu waxay heshay faa'iido tartan ah oo leh natiijooyin hore oo ku saabsan iniinihiisa bishii Nofeembar marka la barbar dhigo heerka hadda jira ee natiijooyinka Febraayo ee ka soo baxa koritaanka jiilaalka. 

Maxaa la bartay

Collectively, the team gained valuable insight that this project has some “how to” components that must be addressed for scalability. When the results were presented to the seed grower cooperator, there was a discussion that supported the need for a larger dataset involving cooperators from different states and seed lots so data with higher confidence could be obtained. The experiment has been repeated with 2021 harvested seed lots and additional seed growers from Idaho, Colorado, Nebraska and Washington. Those growers had all received their own confidential seed test results for PVY, PMTV and TRV by Nov. 18 this year and are awaiting the results from grow-out tests of those tubers for comparison.

Dhinaca sare 

Barnaamijka NPC Vision 2026 wuxuu ugu dambeyntii doonayaa inuu u oggolaado warshadaha baradhada inay isticmaalaan tignoolajiyada tijaabada ee ugu dambeysay ee wax-soo-saarka sare leh, qaarkoodna waxaa loo sameeyay fayraska SARS-CoV-2 iyo noocyadiisa kala duwan. Xubnaha Vision 2026 waxay si firfircoon u raadinayaan la-hawlgalayaal si ay sidaas u sameeyaan. Mashruucan beeraleyda abuurka ah ee lagu horumarinayo qaab beero iyo shaybaar si loo qaato baaritaanka baradhada abuurka ee PCR-ka ee ganacsiga oo leh wax-soo-saar sare iyo sidoo kale in la aqoonsado lana yareeyo caqabadaha ku wajahan qaadashada ballaaran ee habkan ayaa laga yaabaa inay tahay waxa NPC ay fileysay. 

Ka qaybgalka beeraleyda baradhada abuurka ee la filayo ee mashruucan oo ay horseedday rajada ah in natiijooyin laga helo si ka dhakhso badan kuwa caadiga ah ee xilliga jiilaalka ayaa la filayaa inay kor u qaaddo aqbalaadda habkan cusub ee warshadaha baradhada ee Mareykanka. Taas beddelkeeda, u gudubka baaritaanka molecular-ka ee wax soo saarka sare leh ayaa si wadajir ah u siin doona warshadaha baradhada xog caafimaad oo abuurka ah oo dhakhso badan oo sax ah, taas oo hagaajin doonta tayada mustaqbalka iyo rajada ah inay horumariso amniga ganacsiga dalagyada. 

Si kastaba ha ahaatee, waxaan ku soconnaa taxaddar. Habkan beeralayda ee tobanka sano socday ee lagu horumarinayo laguna gaarsiinayo habkan heer sare waa inuu ka ilaaliyaa xad-dhaafka iyo baaritaanka xad-dhaafka ah ee baradhada abuurka, iyadoo la siinayo dabacsanaan si looga jawaabo cudurrada soo baxaya.
