Principles of Plant Breeding (2+1)

Evaluation of test entries

The initial evaluation trial includes the following entries:

• The entries to be nominated must have undergone critical evaluation/screening in the station/ station trials conducted by the sponsoring breeder. Secondly, the entries to be Nominated must have high degree of phenotypic uniformity and genotypic stability.
• The IET is conducted across the zones of all over the country along with check varieties. A minimum of three check varieties comprising of the following is used. i. National check, ii. Zonal check, iii. Location check, IV. Qualifying check
• All the trials are monitored by a team of scientists deputed by project coordinator to record the observations on the uniformity of crop stand, disease and insect-pest, resistance, bird damage etc.
• The main composition of the monitoring team is:
a) Project Director/Project Co-coordinator/PI/Zonal Co-ordinator Team leader
b) Breeder Member
c) Agronomist Member
d) Pathologist/Entomologist Member
e) Scientist from any other specified discipline Member

• The observations recorded according to guidelines on the data books for further supply to the co-ordinators
• The data received at the co-coordinator’s cell is critically examined for the inclusion in the Annual Report.
• Outstanding performance for yield of a variety by a margin of 10% over the best performing check is promoted to advance varietal trial.
