Data are tabulated on the date of first flowering and the % flower survival of the black currant cvs Ben More, Seabrook's Black, Ben Lomond, Green's Black, Ben Nevis and Baldwin exposed to frost (minimum -4.5 deg C) for 4 h. Ben More was by far the latest flowering cv. and showed the best survival, especially with flowers exposed at the grape stage. In a further trial with 17 cvs and selections, plants were subjected to 3 different temperatures (-3.3, -4.5 and -5.2 deg ) each at 3 growth stages (grape, first flower and full flower). Baldwin was worst affected, less than half the flower buds surviving -4.5 deg at the grape stage. Ben More and related selections were best, surviving -4.5 deg at first flower but being susceptible at full flower.
