Pāṇini leaves out words that carry over from earlier sūtras. Expand to see the rule as a reader actually understands it.
तस्य → कुणप्-
Replace tasya with kuṇap-jāhacau when it comes after pīlvādi-karṇādibhyaḥ when pākamūle follows. Inherited words (anuvṛtti) may add further conditions.
Commentary
The affixes कुणप् (कुण) and जाहच् (जाह) come in the senses of 'the fruiting-season of this' and 'the root of this'.
The word तस्य shows that the construction must be genitive. The affix कुणप् comes after पील्वादि words, signifying 'ripening', and the affix जाहच् comes after कर्णादि words signifying the 'root'.
Thus पीलूनां पाकः = पीलुकुणः, कर्कन्धुकुणः, so also कर्णस्य मूलं = कर्णजाहम्, अक्षिजाहम् ॥
