METHOD OF PLANT BREEDING IN CROSS
POLLINATED PLANTS – SELECTION WITH PROGENY
TESTING
With Progeny Testing:
In this method initial plants are selected on the
basis of their phenotype, but the final selection
of plant based on progeny test. This method
includes progeny selection on ear to row method
and recurrent selection.
PROGENY SELECTION (EAR TO ROW
METHOD):
 Hopkins in 1908 developed this method,
extensively used in maize.
A method in which selection is carried
out on progenies derived from individual ears
is called Ear To Row Method.
PROCEDURE
 In its simplest form it consists of
i) 50- 100 number of plants are selected on the
basis of their phenotype and are allowed to
open pollinate. The seeds from individual plants
are harvested separately.
ii) A single row of 10-50 plants i.e a progeny row,
is grown from each selected plant. The progeny
rows are evaluated for desirable character and
superior are identified.
iii) Several phenotypically superior plants are
selected from the superior progenies and
selected plants are permitted to open
pollinate.
iv) Small progeny rows are again grown from
the selected plants, and the process of
selection is repeated.

MERITS EARTO ROWMETHOD:
1.It is based on progeny test and not on the
phenotypes of individual plants hence it is far
more accurate reflection of the genotype than
phenotype.
2.Inbreeding may be avoided if care is taken to
select a sufficiently large number of plant
progenies.
3.Selection scheme is relatively simple and easy.
DEMERITS EAR TO ROWMETHOD:
1. There is no control on pollination and plants are
allowed to open-pollinate. Thus the selection is
based on the maternal parent only
2. The selection time is two years. Thus the time
required for selection is as much as in the case
of mass selection

Ear to row method

  • 1. EAR TO ROW METHOD Department of Genetics and Plant Breeding Faculty of Agriculture Sam Higginbottom Institute Agriculture, Technology and Sciences (Formerly Allahabad Agriculture Institute) Deemed-to-be-University Allahabad Mail Id- mail2devhingra@gmail.com Dev Hingra
  • 2. Nature and man are interdependent; protection of the environment will be in the interest of man himself. – Mahatma Gandhi
  • 3. METHOD OF PLANT BREEDING IN CROSS POLLINATED PLANTS – SELECTION WITH PROGENY TESTING With Progeny Testing: In this method initial plants are selected on the basis of their phenotype, but the final selection of plant based on progeny test. This method includes progeny selection on ear to row method and recurrent selection.
  • 4. PROGENY SELECTION (EAR TO ROW METHOD):  Hopkins in 1908 developed this method, extensively used in maize. A method in which selection is carried out on progenies derived from individual ears is called Ear To Row Method.
  • 5. PROCEDURE  In its simplest form it consists of i) 50- 100 number of plants are selected on the basis of their phenotype and are allowed to open pollinate. The seeds from individual plants are harvested separately. ii) A single row of 10-50 plants i.e a progeny row, is grown from each selected plant. The progeny rows are evaluated for desirable character and superior are identified.
  • 6. iii) Several phenotypically superior plants are selected from the superior progenies and selected plants are permitted to open pollinate. iv) Small progeny rows are again grown from the selected plants, and the process of selection is repeated. Conti..
  • 7. ORIGINAL POPULATION MAY BE REPEATED ONE OR MORE TIMES YIELD TRIALS FIRST YEAR SECOND YEAR THIRD YEAR i) Plants selected on the basis of phenotype ii) Open-pollinated seed from each plant harvested separately i) Small progeny rows grown from the selected plants ii) Superior progenies identified and selected iii) Plants allowed to open-pollinate; seed is harvested separately EAR-TO-ROWMETHOD Same as in second year First selection cycle Second selection cycle Third selection cycle
  • 8. MERITS EARTO ROWMETHOD: 1.It is based on progeny test and not on the phenotypes of individual plants hence it is far more accurate reflection of the genotype than phenotype. 2.Inbreeding may be avoided if care is taken to select a sufficiently large number of plant progenies. 3.Selection scheme is relatively simple and easy.
  • 9. DEMERITS EAR TO ROWMETHOD: 1. There is no control on pollination and plants are allowed to open-pollinate. Thus the selection is based on the maternal parent only 2. The selection time is two years. Thus the time required for selection is as much as in the case of mass selection
