"vigour Ratings (0- 10) 0- foliage lacking vigour, leaves yellowish, 10- healthy foliage Plant Vigour Rating - Irrigation improved the visual plant vigour ratings by a significant difference of 60.4%, Table 2. This large difference was later transformed into seed corn quality and yield. The most vigourous seed corn inbreds were INB 508, Pride #3,4,2 and Hyland T50-B1 while the least vigourous seed corn inbreds were INB 501 and Hyland T22-7B, Table 3. 9
