A different pathway for seed production

Rooted apical cuttings are an early-generation potato multiplication technique developed and promoted by the International Potato Center (CIP). Shoot cuttings derived from tissue-culture plants are rooted in substrate, hardened and planted into protected facilities or multiplication fields, where they produce tubers for subsequent generations.

Potential benefits and limits

CIP reports that under particular production conditions rooted cuttings can improve early-generation multiplication compared with conventional minituber pathways. Those results are not universal yield guarantees. Cultivar, plant establishment, irrigation, soil conditions and trained labour all influence productivity.

Phytosanitary standards remain essential

Planting material from clean tissue culture can help establish a healthy starting point, but field multiplication carries exposure to bacterial wilt, viruses, potato cyst nematodes and other risks. Disease testing, traceability, certification, inspections and suitable crop rotation remain necessary. Each country has its own rules governing the movement and sale of seed potatoes.

Measure success at farm level

Seed companies should compare plant survival, multiplication rate, labour, nursery investment, transport, field losses and the proportion of marketable seed tubers. The measure of success is not simply producing more plants but supplying healthy, affordable seed to growers.
