Breeding of Vegetable, Spice and Tuber crops (2+1)

Procedure of developing composite variety

Year	Main breeding activity
First	Selection of base material, intermating in all possible combination and harvesting crossed seed separately
second	Evaluation of F1 crosses in replicated trial using hybrid or open pollinated variety as check.
Third to fifth	Evaluation of F2, F3 and F4 generations in replicated trial using standard check, identification of crosses exhibiting little or no inbreeding depression.
Sixth and seventh	Mixing parental seed of superior crosses in equal quantity to constitute composite variety, seed multiplication by open pollination in isolation.
Eighth	Release of new composite variety , distribution of seed to the farmers for commercial cultivation.
