RELATIONSHIPS OF FLOWERING DURATION, FLOWERS AND REPRODUCTIVE EFFICIENCY WITH YIELD AND YIELD ATTRIBUTES OF LENTIL VARIETIES/MUTANTS (Pages : 18 - 21)

Lentil is an important pulse crop with high protein content,has the potential capacity to combat nutritional deficiencies in developing countries. Three pot experiments were carried out at BINA, Mymensingh, Bangladesh during winter seasons of 2017-18, 2018-19 and 2019-20 to see the flowering pattern and relationship of flower production, reproductive efficiency and flowering duration with yield attributes and yield of lentil varieties/mutants. The experiment was laid out in a Completely Randomized Design with three replications. Flower production showed differential peak at the middle of flowering duration. Days to flowering ranged from 48-60 days and the flowering duration from 15 to 24 days after flowering started. Total flower number plant-1 ranged from 234 to 686 and reproductive efficiency from 31.3 to 75.5%. Binamasur-6, Binamasur-7 and BARI Masur-4 hadhigher reproductive efficiency. Biological yield plant-1 ranged from 7.40 to 19.21 g and yield plant-1 from 3.10 to 7.51 g. Most of the mutants and Binamasur-8 produced higher biological and seed yield with better harvest index. Number of flowers plant-1 was correlated with biological yield, pods plant-1, and negatively correlated with reproductive efficiency. Biological yield was also correlated with pods plant-1. Pods plant-1 was correlated with reproductive efficiency and seed yield plant-1. Seed yield plant-1 was correlated with pods plant-1 and seeds pod-1. But these relationships did not equally exist in three years and no relationship was found between flowering duration and yield. Relationship was not also found between pods plant-1, seeds pod-1 and 100-seed weight. Download
