Removal of Apical Dominant Shoot for Disease Resistance Screening Increases Seed Yield of Container‐Grown Plants

Abstract

Host plant resistance is generally included as a means of mitigating production losses in peanut (Arachis hypogaea L.). Testing methods which do not impact yield are of particular value in the development of cultivars. The objectives of this research were to determine the viable seed yield of container-grown peanut plants and the impact of removing the apical dominant shoot on seed set, for use in disease testing. Two resistant cultivars, Tamspan 90 and Southwest Runner, and two susceptible cultivars, Okrun and Flavor Runner 458, were crossed in a diallel to produce F 1 seed. A total of 191 F 1 plants were evaluated in the greenhouse under two treatments, apical shoot removed or not removed, in 2003 to 2005. The mean seed set of the control group (apical shoot not removed) was 12 seed per plant compared with 15 seed per plant when the apical shoot was removed.

Effect of Decapitation on the Growth and Yield of Pepper (Capsicum annuum l.) in Obio Akpa, Akwa Ibom State

“…In soybean, removing the apex during the early flowering stage increased yield by 10 -15 % according to Andrea et al (2006). In groundnut, the number of seed sets per plant was increased by 24% when the apical dominant shoot of the plant was removed (Andrea et al, 2006).…”

Brown et al (1967), who studied the effect of ethno-agricultural practice on the production of marketable fresh fruits and seed production for 12 okra cultivars under two cropping seasons also reported that decapitation affected the yield of okra.…”
