A long pedicelled mutant and its inheritance in grasspea (Lathyrus sativus L.)

Abstract

Pedicel is a flower bearing axis. In grasspea (Lathyrus sativus L.) pedicel terminates in a single flower and its length varies in a limited range. Conspicuous reduction in the length of pedicel was, however, noticed in a dwal1 mutant of grasspea var. Bio R-231 showing very poor yield [1]. In contrast to this, unusually long pedicel was detected in an induced mutant manifesting earliness in flowering and maturity with considerably higher yield in the same variety. Characteristic features of the mutant and inheritance pattern of the length of pedicel have been stated in the present text.
