3. 680 DD after biofix 2.1-1st tiller visible
4. 1000 DD after biofix 3.1-1st node detectable
5. 1320 DD after biofix 4.1-flag leaf sheath extended
6. 1650 DD after biofix 5.1-tip of inflor. emerged, 1st spiklet just visible
7. 1960 DD after biofix 6.1-1st anthers of flowers visible
8. 2290 DD after biofix 7.1-1st grains reach half of final size
