Selection for fast germination in rapeseed brassica napus l. and brassica campestris l

Euphytica 35(3): 835-842

Selection for fast germination in rapeseed brassica napus l. and brassica campestris l

Eleven populations of Brassica napus L. and twelve populations of B. campestris L. were subjected to three cycles of selection for fast germination at C and C. The seeds from the selected populations, and unselected control populations grown in the same environment as the selected populations, were examined for germination behaviour at C and C, and for growth behaviour at C. The populations in both species responded differently in terms of germination behaviour to selection for fast germination. In most of the populations that did respond positively to selection, selection practised at C was superior to selection at C in improving percent germination at C, and was as good as the selection at C in improving germination rate at the higher temperature. Selection for fast germination had no effect on growth characteristics of B. napus and B. campestris populations grown at C. Thus, selection for fast germination at one low temperature may lead to improvement in germination characteristics over a range of temperatures, but will not necessarily lead to improved growth performance of the selected populations.
