Evaluation of pod, seed, and phenological traits of common beans
Germinability
Tests of germinability followed the “International Regulations for Seed Testing” (ISTA
1999). Depending on size and number of available seeds, 50 to 100 seeds are set up
in germination rolls (substrate: moistured filter paper) in a germination bank. Seeds
are germinated between two layers of paper at 20°C room temperature. First counts
are carried out after five days, final counts after nine days. Analysed are healthy,
germinable seeds, hard and fresh seeds, as well as abnormal and rotting seeds. The
computed germinability in per cent is derived from the number of healthy and germinable
seeds.
Measurements on pods and seeds
Figs. 1 and 2 show the range of variation of the accessions investigated. In order to
carry out measurements on pods (Fig. 3) and seeds (Fig. 4), the PC software QWin
and a 3CCD Colour Video Camera connected to the PC were employed. This type of
