Abstract: | Summary The number of days to flowering and the number of flowers per plant were studied at 12, 13, 15 and 17 C night temperature in 79 F1 populations from 15 parents. Only a few F1 plants flowered earlier than their parents; the majority flowered at the same time, later or not at all. The number of flowers of the F1 plants was higher than that of the parents.Genetic analyses showed a broad sense heritability of 70% for days to flowering and flower number and a highly significant GCA effect for days to flowering.The progenies and parents that flowered early at one temperature were generally early at all temperatures. |
