P1 are the parents and F1 are the offspring of the parents. P1 is the "parental generation" and F1 all looked different because they represented only the dominant trait. The F1 offspring showed only one of the 2 parental traits. For example, in one of his experiments he crossed a homozygous tall plant with a homozygous short plant(P1) and the offspring(F1) were all tall plants, because "tall" was the dominant trait. The short plants all "skipped" the F1 generation and the recessive traits showed up in the F2 generation when a dominant trait was not present. Because of that, he ended up with a variety of different offspring.
