Early identification of determinate growth habit in lablab bean (Lablab purpureus (L.) sweet)

Rapid and reliable information for early identification of determinate growth habit is highly desired in the high yielding determinate variety development program. This experiment was conducted to find out some effective morphological markers for the early identification of determinate growth habit of lablab bean. Both determinate and indeterminate plants were grown in 20 °C and 25 °C of phytotron in the summer and winter seasons of two consecutive years. The results of this experiment suggest that though the growth and development of lablab bean is influenced by growing environment, still it is possible to identify determinate growth habit within three to 11 weeks after seed sowing at any season. This can make early selection of determinate growth habit possible for variety development program.
