(Mishnah): If a person sold seeds to his friend and they did not grow, even if they are flax seeds (which are usually used for planting rather than eating), he does not need to pay.

Rabban Shimon ben Gamliel: If they were seeds of the vegetable garden that are not eaten, he must pay.

If a person sold seeds to his friend, the buyer must accept a quarter of a kav of waste for each se'ah.

For figs, he must accept 10 wormy figs for every hundred.

For wine barrels, he must accept 10 barrels of sour wine for every hundred.

For bottles of wine in the Sharon region, he must accept 10 bad bottles for every hundred.

If a person sold wine to his friend and it soured, the seller is not responsible.

If the seller knew that his wine sours, it is a mistaken acquisition.

If he told the buyer that he is selling him wine that will remain sweet, he must supply wine that remains sweet until Shavuos.

If he sold him 'yashan' wine, he can give him the previous year's wine. If he sold him 'meyushan' wine, he must give three year old wine.

(Beraisa): If a person sold seeds to his friend and they did not grow, even if they are flax seeds, he does not need to pay.

But if he stipulated with him that is buying it to plant, the seller must pay.
