Performance and Genetic Diversity Pattern in the Landraces of Allium cepa L.

Abstract

Performanceanddiversity pattern are very muchimportant
to applied crop breeding, because diversity may reduce
vulnerability to pests and at the same time accelerate
breeding progress for agronomic trait such as yield.
The continuing use of diverse landraces and exotic
modem cultivars as parental stock in recent decades
has been associated with improved yield and pest
resistance in many vegetablecrops.Astudywas undertaken
to understand the potentiality of the landraces in terms
ofyield and thediversity pattern existing in the population.
The results of this experiment are presented here.
