Indica inbreds produced significantly more tillers than
hybrids and NPTs (Table 4). There was no significant difference in maximum tiller number between hybrids and NPTs. The NPTs generally had a higher productive tiller
percentage than either indica inbreds or hybrids. The difference in plant height among the three groups of rice culti-vars was not consistent across seasons (Table 5). In general,
indica inbreds were shorter than hybrids and NPTs. Panicle
size per unit plant height at flowering was higher in hybrids
than in indica inbreds or NPTs in all four seasons. There
was no consistent difference between indica inbreds and
NPTs in panicle size per unit plant height at flowering.
Panicle size per unit plant height at flowering was greater
in the DS than in the WS.
