- A scientific explanation of the Doubled Haploid (DH) technique, including a step by step guide for the creation of a DH line. The video also describes the necessary attributes for a successful DH program in public or private institutions. A joint production of the International Maize and Wheat Improvement Center (CIMMYT) and the University of Hohenheim.

one of the best presentation to learn about this technique
Very excellent work on maize, I do needs to know more about this. Thanks
Thank you for sharing this with us.
Great video. Thank you for sharing
Great explanation.
it is a very quick and effective breeding method
great explanation indeed
Great video and so clear --
Very educational....I will try to learn this...👍
excelent method.
greetins from Peru
Excellent video
Nice information!
La tecnologia de Dobles Haploides, es una excelente herramienta para los mejoradores, reduce el tiempo para la obtencion de lineas puras.
yes, these are quite special fruit crops where the double haploid technology most possibly isn't yet.
really useful method
very useful... method.
Nice presentation
very helpful
wow amazing
Very nice video
really helpful
double haploid technology works with many other crops - including wheat, potatoes, etc. But in almost each crop there is a slightly different way how to induce and identify the haploid plants.
very interested lecture
Good information
How much colcisin dosage?
I have three questions:
1. What are the minus points of DH breeding which brings homozygosity so fast?
2. What are the accomplishments of CIMMYT through DH breeding method?
3. Could this money have been used for simpler traditional technique for greater corn advancement compared money and time CIMMYT spent on DH breeding method?
are you got answer?
Double haploid currently does not work with Fragaria or passiflora. There can induce polyploids by a safer method than using colchicine is NO2 gas or using Oryzalin. I am currently using both mass selection and progeny selection only.
Nice. I learned a lot..........
It is time saving method.
a suitable method. ?

It is too bad this only works with corn
Isn’t that Tetraploid?
Almost, but no.
Respected sir, I need the answer f below question. No one know the answer if you know please give its answer.
(Your company has a highly successful tomato cultivar. It is a hybrid between two inbred lines that you developed.
Recent years, a cultivar similar to the hybrid cultivar emerged. The seed are very cheap, and the market f your cultivar started to dwindle.
Since it is a hybrid and you thought that the cultivar is well protected from thieves. However, the cultivar from the other company has no phenotypic differences from your cultivar. You started to think that the other company stole your cultivar. How will you collect the data before you sue the company? Be sure that your data are reliable and your logic has no flaw.
Otherwise, the judge will not rule in favor of your company. )
Your best bet here would be to use molecular markers and register marker results when the cultivar is registered. Molecular marker variation is widespread in corn and the chances of two cultivars exhibiting the same marker pattern are very small. Also, if the other company had stolen your cultivar, as it it a hybrid (F1), they would have had to have stolen both parents in order to produce the hybrid seed!
