✦ Synopsis

A comparison

between the Royal Red bean variety and a reduced leaf mutant on the basis of growth indices is reported.

The mutants has lower leaf area index (LA]) and leaf area duration (LAD) (43.7%). higher specific leaf weight (SLW) (on the mean + 33.3 I',) and accumulates less dry matter (-7.7 I',,) than the normal genotype.

When the net assimilation rate (NAR) is considered. the mutant is superior to the normal (f62.3 :,). It is concluded that the unit area of the mutant leaves accumulates dry matter more efficiently than that of the corresponding normal variety.
