F3 RESPONSE TO F2 SELECTION FOR QUALITY AND ITS EFFECT ON F3 YIELD DISTRIBUTION

Abstract

Seed of F2 single plant selections from two crosses was evaluated using a number of small-scale quality tests.F2 quality test values were significantly correlated with farinograph and extensograph properties in the F3, but no one test was correlated with all of the physical dough measures. The Pelshenke time and the proportion of residue protein were the small-scale measures most consistently correlated with dough strength (farinograph dough breakdown and extensograph maximum resistance) in the F3 and between the F2 and F3 generations.Applications of independent culling in the F2 for each test did not alter the subsequent nature of the F3 yield distribution except for flour protein content a..
