1. Seed. Sour lime is mainly propagated by seed. Propagation by seeds is followed due to polyembryonic nature of it. In sour lime about 78 per cent seeds possess polyembryos. Each polyembryonic seed produces three to four seedlings. Among them, one is sexual origin and remaining are nucellar. Nucellar or apogamic seedlings breed true to type. Polyembryonic.

2. Vegetative. Layering. Budding on Rough Lemon.
Raising of seedling :- Freshly extracted seeds are sown on well prepared nursery bed at the distance of 20 x l0 cm and 1.5 to2cm deep. Germination completes within 3 weeks. The sexual seedlings, which are usually stunted and poor in growth compared to apogamic or nucellar seedlings, are uprooted carefully. Removal of sexual seedlings is essential because they do not breed true to type. The apogamic seedlings are identical to the parent in growth and production. Seedlings are ready for transplanting 6 to 9 months after sowing. However, usually one year old seedlings are preferred for transplanting. Seeds are sown in seedbed during July- August.
