Breeding methods in asexual crops. UMK KAMPUS JELI

There are few ways
1. plant introduction
2.clonal selection
3.hybridization
4.mutation breeding

there are small pollen...really small and tiny..

CORN tree

Corn pollen that still attach to the the tree

small baby caladium tree... did you know that usually the shoot of tree free from pathogen?

for clonal selection...its more take time

year 1

assemble the clonal population. Plant are expose to disease of interest. select resistant cones with other superior traits and harvest individually.

YEAR 2

Grow progenies of selected clones and evaluate as in year 1. select superoir clones

year 3

CONDUCT preliminary yield trials. slect superior clones.

year 4-6

conduct advanced yield trials at multilocations for cultivar release.

FOR  you extra knowledge , hybridization with clonal selection only cen be done with

1.species that are capable of producing seed in appreciable quantities.

pop quiz!

what is hybrid cultivar!?

answer:

the F1 heterozygote that has yhbrid vigor.heterosis effect that superior that both parents.

Usually F1 ARE HETEROZYGOTE..F2 are segregate.

for example

AaBb -----------> COULD BE

AABB AABb AAbb aaBB AABb aabb,..

NEXT IS mutation breeding.

MUTATION OCCUR IN INDIVIDUAL CELLS.

HETEROSIS ARE only occur at heterozygosity.

AND 

heterozygosity > homozygosity . Its due to the abundat of recessive genes at homozygosity and the probability of recessive genes to occur are easy.

SMALL BABY corn

small baby seed corn taht start to emerge the roots

ALHAMDULILLAH..today this is what i had learnt. Thanks Dr Dwi. Susanto for this subject Plant Breeding Subject,
:)
ALHAMDULILLAH.!!
TAKBIR!!

next entry , nak tulis pasal agropark :)
