An approach to establish inbreeding tolerant base population in maize (Zea mays L.)

Published on

Hybrid maize breeding is dependent upon the extraction
of good and vigorous inbreds from the source populations.
However, progress is impeded more often owing to chronic
inbreeding depression. The present investigation aimed
to form an inbeeding tolerant base population through
the use of the genetic parameter of inbreeding depression
(ID). In this endeavour, the nine crosses which showed
non-signifiant inbreeding depression with better mean
performance in the F2 generation were selected to
constitute the base population for an important trait namely
performance index (PI).
