Seed Yield is not Impaired by Chromosome Stickiness in Sodium Azide Treated Trigonella foenum-graecum

Abstract

Partial or complete stickiness of chromosomes and disorientation of spindle were the major anomalies observed in meiocytes of Trigonella plants raised from seeds treated with different concentration of sodium azide for three durations. Other aberrations were unequal separation, non synchronous division, bridge, laggard, stray etc. The pollen fertility and yield showed an increase over control despite the high frequency of stickiness and spindle disorientation. Yield was positively correlated with stickiness, indicating a balancing/regulatory effect of stickiness at the time of gamete formation.
