Abstract

A field test of eleven promising Holland Irish potato varieties was made at low elevation in 1967. The results revealed that Gineke, Desiree, and Plato were the heaviest yielders. Varieties Gineke, and Plato were the most vigorous. In general closer spacing (20 x 20) gave higher yield than either 30 x 30 or 40 x 40 cm. spacing. CB 52-105-9 gave the broadest while Multa the longest tubers. Varieties PlatoDijkhuis 52-211, CB 52-105-9, Atleast, and Gineke had a high proportion of class I's, 30 per cent or more; while Mentor, Radosa, Multa. Desiree and Spartaan gave 25 to 30 per cent; and Furore, the poorest, was below 24. The differences among varieties in class II yield was practically the same; class III's, Gineke and Furore were highest; and class IV's or discards were Gineke, Multa, and Dijkhuis 52-211. Shape and smoothness uniformity increased with decrease in spacing while size and eye prominence increased with increase in spacing. Atleast, Dijkhuis 52-211, Gineke, Multa, Plato and Spartaan were the most resistant to soil-borne diseases.
