Studies in Dolichos lablab (Roxb.) and (L.) - the Indian field and garden bean. I

Abstract

Dolichos lablab exists both as a field and as a garden variety. The latter has evolved out of the former. The downward hairs (H) in the internodes of the garden variety are a simple dominant to the upward hairs(h) of the field variety. Erect pods (E1, E2 or E1E2) are dominant to drooping pods (e 1 e 2). Two factors exist, either of which or both might give erect pods. In the absence of both, pods droop. Pods of medium width (W1) proved dominant to pods of narrow width (w1). In narrow podded garden varieties the septate (S) condition of the pods proved dominant to the non-septate (s) bloated condition. In field varieties all pods are green in colour. In garden varieties pods may also be light green in colour. This difference is reflected in the whole plant. The normal green colour (Ca) is a simple dominant to the light green (ca ).
