If one plants tamei terumah, is the gedulin [product] also tamei?

Question

Mishnah Terumos 9:4 explains that, if one plants terumah, then the product which grows (gedulin) is also terumah drabannan.

My question - if the seeds planted were tamei terumah, is the product also tamei terumah, or just regular tahor terumah?

Answer 1

The Mishnah in Terumos 9:7 says that they become regular teruma but can’t be eaten as a chumra:

שְׁתִילֵי תְרוּמָה שֶׁנִטְמְאוּ, שְׁתָלָן, טָהֲרוּ מִלְּטַמֵּא, וַאֲסוּרִין מִלֶּאֱכֹל עַד שֶׁיָּגֹם אֶת הָאֹכֶל. רַבִּי יְהוּדָה אוֹמֵר עַד שֶׁיָגֹם וְיִשְׁנֶה

Saplings of terumah which had become unclean and were re-planted, become clean from their uncleanness. But they must not be eaten until the edible part [of the stalk] has been lopped off. Rabbi Judah says: he must [before eating] lop off a second time that which grew on the edible part

The Bartenura explains that the prohibition of eating it until removing the eatable part is a chumra
