It's an upgrade of a Lobbed-Shot Plant, so it's a Lobbed-Shot Plants!

Repeater ---> Gatling Pea: Peashooting Plants

Sunflower ---> Twin Sunflower: Sun Producing Plants

Fume-shroom ---> Gloom-shroom: Mushrooms

Lily Pad ---> Cattail: Aquatic Plants

Melon-pult ---> Winter Melon: Lobbed-Shot Plants

Magnet-shroon ---> Gold Magnet: Magnet Plants

Spikeweed ---> Spikerock: Spike Plants

So: Kernel-pult > Cob Cannon must be Lobbed-shot Plants!
