Gwyddor Cnydau a Bridio Planhigion - Cnydau Porthiant

 

Mae cnydau porthiant yn chwarae rhan hanfodol mewn amaethyddiaeth da byw, gan ddarparu bwyd anifeiliaid a chyfrannu at gynhyrchiant a chynaliadwyedd cyffredinol y diwydiant da byw. Mae gan IBERS hanes hir o ymchwil ar gnydau porthiant, gan wella nodweddion genetig ar gyfer gwell cynnyrch, ansawdd maethol, a gwytnwch amgylcheddol. Mae gwyddoniaeth IBERS yn sail i 47 o amrywogaethau ABER o laswellt a meillion ar y Rhestr Amrywogaethau Genedlaethol bresennol yn y Deyrnas Unedig, wedi’u masnacheiddio gan ein partner hirdymor Germinal Horizon Ltd. Trwy gydweithio rhyngddisgyblaethol a masnachol, nod IBERS yw hybu systemau cnwd porthiant cynaliadwy a gwydn i gefnogi amaethyddiaeth da byw a darparu’r wyddoniaeth angenrheidiol i helpu i fridio a masnacheiddio amrywogaethau newydd.

Biotechnoleg

I ategu ein dealltwriaeth o strwythur a swyddogaeth genynnau, yn enwedig ar gyfer rheolaeth enetig ar ail-gyfuno a nodweddion eraill yn ymwneud â bridio, rydym ni’n cynnal ffrwd trawsnewid mewn nifer o rywogaethau yn cynnwys Brachypodium a Lolium perenne. Mae’r ffrwd hon hefyd yn hwyluso datblygu ac optimeiddio golygu genynnau’n seiliedig ar Crispr yn y rhywogaethau hynny.

Nodau

Nodau Bridio

Mae’r nodau tymor hir o ran bridio sydd angen mewnbynnau o ymchwil sylfaenol yn cynnwys:

  • Ymgorffori bridio gyda chymorth genomeg i gyflymu enillion genetig.
  • Ymelwa ar ddata dilyniannu genom i ddeall nodweddion a chroesfridio uniongyrchol yn well
  • Defnyddio technoleg newydd (dronau, dysgu peiriant, deallusrwydd artiffisial) ar gyfer ffenoteipio yn y maes.
  • Targedau bridio ar gyfer ffermio digarbon a hinsawdd-gyfeillgar - dal a storio carbon, tyfu gwreiddiau, gwydnwch i’r newid yn yr hinsawdd, dyfalwch.
  • Gwella effeithlonrwydd y defnydd o faetholion i leihau mewnbynnau.
  • Bridio porthiant gyda nodweddion ansawdd gwell sy’n lleihau allyriadau nwyon tŷ gwydr.
  • Defnydd newydd o gnydau porthiant, codlysiau a cheirch fel echdynnu protein ar gyfer porfa monogastrig a diet yn seiliedig ar blanhigion.
  • Gwell gwydnwch i nodweddion ansawdd grawn (ceirch) i ateb y galw gan felinwyr a defnyddwyr.
  • Goddefgarwch a gwydnwch aml-straen i ddigwyddiadau tywydd niweidiol sydyn (sychder, dyfrlenwi).
  • Gwell effeithlonrwydd bridio (cywirdeb dethol) gan ddefnyddio ffenoteipio trwybwynt uchel.
  • Rhag-fridio i nodi alelau newydd a chynyddu amrywiaeth genetig.
  • Deall addasu – cydweddu ffenoleg â’r amgylchedd.
  • Datblygu meincnodau i ffermwyr a modelau tyfu cnydau.
  • Mynd i’r afael â’r bwlch cynhyrchedd amaethyddol drwy welliannau i gynnyrch cnwd a sefydlogrwydd cynnyrch.
  • Dulliau newydd o fridio planhigion (golygu genynau, bridio cyflym) a rheolaeth ailgyfuno
