Ansawdd Hadau
Mae ansawdd yn thema barhaus drwy gydol y broses gyfan o gynhyrchu hadau.
Pam mae ansawdd hadau’n bwysig?
Mae cynhyrchwyr hadau am gynhyrchu hadau o’r ansawdd gorau. Fel tyfwyr, gwyddom y bydd hadau o ansawdd da yn dangos cyfraddau egino gwell ac mae modd eu storio am fwy o amser. Maent yn cynhyrchu planhigion iachach gyda mwy o ymwrthedd i blâu a chlefydau a byddant yn cynhyrchu cnwd da.
Mae'r taflen cyngor yn cynnwys:
Cnydau Hadau Iach
Planhigion iach = hadau iach
Mae tyfu’n ffactor eithriadol o bwysig o ran ansawdd hadau. Bydd darparu’r amodau tyfu gorau posibl ar gyfer eich cnwd yn cynhyrchu planhigion iach ac egnïol i arbed hadau. Bydd planhigion dan straen yn cynhyrchu blodau a hadau fel yr ymdrech olaf i oroesi, ond ni fydd yr hadau o’r ansawdd gorau.
Plâu a Chlefydau Hadau
Yn gyffredinol, gall problemau o ran plâu a chlefydau wanhau iechyd planhigion yn sylweddol ac, o ganlyniad, ansawdd hadau. Mae potensial hefyd i glefydau gael eu trosglwyddo i'r genhedlaeth nesaf drwy hadau heintiedig.
Clefydau a Gludir gan Hadau a Phathogenau?
Sut rydyn ni’n gwybod pryd mae clefyd neu bathogen yn cael ei gario ai peidio? Os yw pathogenau’n cael ‘dechreuad cynnar’ drwy fod eisoes yn bresennol ar yr had pan gaiff ei hau, byddant yn cael effaith llawer mwy negyddol ar y planhigyn sy’n datblygu.
Triniaethau Hadau
Mae rhai triniaethau hadau organig ar gael i leihau pathogenau bacteriol a ffwngaidd.

19/02/2021 18:22:04Producing an open pollinated seed crop on your farm can improve the quality of your future crops, increase plant adaptation to local conditions, give you access to new varieties and new skills. Seed production can also bring an added income stream to…
02/02/2021 16:21:49This third session will look at the principle involved at the selection stage through to harvest. The session covers: Importance of population size to inbreeders/outbreeders The role of selection in seed production – how to determine what is “true-to…
04/08/2020 11:11:39The second cultivation session builds on the first session and look at trickier crops – annuals that will readily cross-pollinate and biennials that require overwintering methods. The crops covered in this session are: Runner bean Broad bean Cucurbit…
23/07/2020 15:01:20This session introduces the key principles and looks at what we would consider the easiest crops to cultivate for seed – annuals that self-pollinate or annuals with simple isolation and pollination requirements.
23/06/2020 14:17:11The Gaia Foundation and Tyfu Cymru are working in partnership to deliver training in open pollinated vegetable seed production in 2020.
