About this variety
JS 20-29 is a medium-maturing soybean variety bred at JNKVV, Jabalpur, from the cross JS 97-52 × JS 95-56 — built on the waterlogging-tolerant line JS 97-52 — and released for India’s Central Zone. It gives a real yield step-up over JS 335 and has been displacing the older variety across much of Madhya Pradesh since its release.

Advantages & considerations
Why farmers may choose it
- Bred from the waterlogging-tolerant line JS 97-52, giving it an edge where standing water after heavy kharif rain is a recurring risk
- A genuine yield step-up over JS 335, the reason it has been displacing the older variety across much of Madhya Pradesh
Things to consider
- Reported yield varies by source: the conservative range is 20–22 q/ha, though some seed-trade pages report 25–30 q/ha under good management

Frequently asked questions
Why is JS 20-29 replacing JS 335 in Madhya Pradesh?
It gives a documented yield step-up over JS 335 while keeping a similar short-to-medium duration, so it fits the same cropping calendar with better returns — the reason growers across much of the state have been switching.
Does JS 20-29 handle waterlogging better than older JS varieties?
It was bred using the waterlogging-tolerant line JS 97-52 as a parent, which is intended to give it an edge in fields where standing water after heavy kharif rain is a recurring problem — a documented breeding objective, though field performance still depends on how long and how deep the waterlogging is.
