ABSTRACT
Productivity of flowering nodes in three lentil (Lens culinaris Medik.) genotypes

In order to establish the profile of productivity of the lentil plant, the yield, yield components, and aborted flowers retained to maturity at every flowering node, were evaluated on Araucana-INIA, ILL-28, and Laird genotypes. The study was conducted at the Carillanca Exp. Sta. (INIA, Temuco) during the 1983/84 season. Pods/node, seeds/pod, seed weight, and yield/node were highest at the lowest nodes of the branches, becoming progressively reduced upwards. Only in Laird, the seeds/pod component was not altered throughout the branch profile. Nades 1 to 3 on primary branches and node 1 on secondary branches were the most productive, contributing with 71.2, 91.1, and 67.6% of the yield/plant in Araucana-INIA, ILL-28 and Laird, respectively. Improductive (empty) pods averaged 22% at the lowermost and 100% at the uppermost pod-bearing nodes. Aborted flowers were observed mainly in the upper section of the branches, contributing from 52 to 100% to the reduction of pods at the uppermost reproductive nades.
