These are seedling jackfruits (soft flesh & easier to open than crunchy varieties). Excellent as a seedling fruit or disease resistant rootstock for grafting or top working.  Jackfruits are the world’s largest tree-bearing fruit. Versatile in use from using the green (unripe flesh) as a meat replacement, or eating the juicy flesh as fruit. The seeds are a great protein source and can be boiled, roasted and made into things like hummus or veggie burgers. For more info on jackfruits check out Katie’s Tropical Kitchen article:
