Munzvimbo dzine makomo dzeNepal neBhutan, uko nzvimbo yakaoma uye yakasarudzika mamiriro ekunze anogadzirisa maitiro ekurima, mbatatisi yave chirimwa chakakosha. Haangobatsiri zvakanyanya mukuchengetedzeka kwechikafu, asi anotsigirawo mararamiro evarimi uye anoita basa rakakosha mumisika yemuno neyekunze. MuBhutan, pamusoro pe22% yedzimba dzevarimi dzinovimba nekurima mbatatisi, ichigadzira angangoita 38,000 metric toni pagore, yakawanda yacho inotumirwa kunyika dzakavakidzana. Saizvozvo, muNepal, mbatatisi iri pachinzvimbo chechina chakakosha chirimwa mushure memupunga, chibage, uye gorosi, zvichipa zvinopfuura 6% kuGDP yenyika.
Mbatata inonyanya kukosha munzvimbo dzakakwirira-dzepamusoro dzeNepal, uko dzinopa nzvimbo inokosha yekudya kunovaka muviri munzvimbo umo zvimwe zvirimwa zvinganetsa kukura. Kuwedzera kuri kuita mbatatisi kunoratidza kukosha kuri kuwedzera kwechirimwa munzvimbo idzi. Parizvino, goho muNepal rinobva pamatani gumi kusvika gumi nemanomwe pahekita, asi pane mukana wekuwedzera huwandu uhu nekutanga kurima kuri nani uye mhando nyowani dzembatatisi.
Apa ndipo panotanga kunetsa basa reInternational Potato Center (CIP). Iyo CIP yakatanga chirongwa chekusimudzira kugadzirwa kwembatatisi muNepal neBhutan nekudzidzisa masayendisiti emuno hunyanzvi hwekugadzira mbeu uye maitiro ekusimbisa mhando. Kuedza uku kwakanangana nekupa zvikwata zveNational Potato Programme neruzivo uye maturusi anodiwa kuvandudza kugadzirwa kwembeu uye kuwana mhando dzemhando yepamusoro, dzinosimba.
Mukudzidziswa kwechangobva kuitika muBangalore, India, vatori vechikamu kubva kuBhutan neNepal vakaunzwa kune yekucheka-kumucheto matekinoroji senge midzi apical cuttings (RAC) uye Loop-Mediated Isothermal Amplification (LAMP) assays. Iyo tekinoroji yeRAC inobvumira kukurumidza kuwanda kwemhando nyowani dzembatatisi nekushandisa madiki ekucheka kubva muzvirimwa, zvichideredza zvakanyanya nguva inodiwa pakugadzira mbeu. Iyi nzira inobatsira zvakare kudzikisira kubatwa nezvirwere zvinobatwa nevhu, kuita kuti varimi vave neutano uye vanotengesera mbeu mbatatisi.
Iyo LAMP assay tekinoroji chishandiso chekuongorora chinoona utachiona hwechirimwa pachine nguva, chinopa varimi mukana wekutora matanho ekudzivirira zvirwere zvisati zvapararira. Izvi zvinonyanya kukosha munzvimbo dzepamusoro-soro, uko kutonhora kwemamiriro ekunze kunogona kuwedzera nyaya dzehutano hwezvirimwa. Nezvishandiso zvitsva izvi, CIP iri kubatsira varimi kurwisa zvimhingamipinyi zvakaita sezvirwere, tumbuyu, negoho riri kusanduka, uku ichikurudzira kutorwa kwembeu dzakavandudzwa nehunyanzvi.
Chirongwa chekudzidzisa, icho chaitungamirirwa nenyanzvi dzakadai saDr. Kalpana Sharma, VaRavindranath Reddy, naVaElly Atieno, vakabatanidzawo kudzidziswa kwemumunda. Vatori vechikamu vakadzidza zvese zve theoretical uye maoko-pane maficha ekugadzirwa kweRAC uye kuendesa kweLAMP assays. Kubatanidzwa kwevadzidzi vanobva kuYunivhesiti yeHorticultural Sayenzi Bagalkot kwakawedzera kupfumisa ruzivo rwekudzidza, kuchikurudzira kubatana munyika dzese.
Ichi chirongwa chikamu chekuedza kwakawanda kusimbisa masisitimu embeu muNepal, Bhutan, neIndia, kubatsira varimi kuwedzera goho rezvirimwa uye kusangana nezvinodiwa zviri kuwedzera. Nekutarisa pamhando yembeu uye kutonga kwezvirwere, basa reCIP riri kubatsira mukusimudzira nharaunda dzekumaruwa nekutsigira kuchengetedzwa kwechikafu muHimalayas.
Kuunzwa kwehunyanzvi hwekugadzira mbeu uye tekinoroji yekuongorora chirwere, senge RAC uye LAMP assays, iri kubatsira kushandura kurima mbatatisi muNepal neBhutan. Nezvirongwa zvembeu zvakavandudzwa, varimi vakashongedzerwa zvirinani kurima mbatatisi dzinopa goho repamusoro, dzinoshingirira kuzvirwere, vachiona kuchengetedzeka kwechikafu nekugadzikana kwehupfumi. Kufambira mberi uku hakusi kungosimudzira goho rekurima chete asiwo kupa varimi venzvimbo iyi simba rekuzadzisa kudiwa kuri kuita mbatatisi mudunhu iri.
