of 10 (Fig. 6). Plant growth characteristics were assessed by measuring the average plant heights on July 15 and August 8, and plant vigour ratings on July 1 1 and 30. Seed quality and seed corn cob characteristics were assessed at harvest on September 28 by measuring and averaging the length of 10 cobs per plot, lining across 10 cobs and measuring the total width, counting the number of cobs per treatment, counting both kernel numbers per row and number of rows per cob. Yield assessments were taken weighing the cobs with husks on and off and converting the weights to a given 18% moisture, recording the actual field moisture at time of harvest and providing shelled corn yields adjusted to 18% for each seed corn inbred. OBSERVATIONS Drought Spiking - Certain inbreds showed early spiking, narrowing and twisting of leaves, Fig. 4, responding to the dry soil conditions. The most spiked seed corn inbreds were Hyland T22-7B and INB 507 while the least spiking occurred in inbreds Hyland T50-B1, Pride #1 and 2, Fig 5.The Pride seed corn inbreds were all relatively tolerant to early dry soil conditions. Table 1. Fig 4. Drought spiking showing narrowing and twisting of leaves.
Fig. 5. Spiking, narrowing and twisting of leaves, responding to the dry conditions on June 23. The shorter the bar the less tolerant to drought. The lower the number the more leaf spiking. 0= severely spiked, 10= normal Stem Colour - a number of seed corn inbreds showed a characteristic purpling of the lower stems early in the season, Fig. 6. The inbreds which showed the most stem purpling were Hyland T22-7B, Hyland 4097, INB 502,503,506,507 and Pride # 4. Table 1. Fig. 6.
