Abstract

An experiment was conducted at Mymensingh (24°75'N, 90°50'E) between November 1999 and April 2000 to investigate variation in sink (raceme, flower and pod) production and reproductive abscission levels on mainstem and primary (1°) branches and their relationships with yield and yield attributes in four short duration pigeonpea morphotypes. Results revealed that total number of racemes/plant varied between 45 and 190 and that of flowers/plant between 343 and 2096 while percentage of floral abscission varied between 89 and 94. The pod yield/plant varied between 35 and 119 g/plant and that of seed yield/plant between 7 and 27 g/plant among the morphotypes. It was observed as much as 85 to 89% of the total racemes and 71 to 80% of the total flowers were borne on the 1° branches. Pod and seed yield (70 to 93% and 67 to 80% of the total pod and seed yield, respectively) was also greater on the 1° branches. Results conclude that genotypic variation exists in sink (raceme and flower) production and floral abscission on mainstem and 1° branches, and increased sink production on the 1° branches may be used as a selection criteria for improved yield in short duration pigeonpea
