Abstract

Seed samples of 100 grams of six cotton cultivars, from two locations and four primings (harvesting) were classified into good, immature and insect-infested seeds. Seeds derived from Batac and from the first and recent primings had less immature and infested seeds and had high percent seed germination. Among the cultivars, All appo contained more good seeds.

Significant differences were observed between locations, cultivars and primings in terms of percent seedling emergence and height. Seeds from the first priming had higher seedling emergence, height and dry weight.

Significant differences on the average plant height number of bolls and seed cotton yield were observed between cultivars and primings but not between locations. Plants from the first and second primings grow taller and produce more bolls than those from later primings which indicate that seeds from early primings are the best to plant to obtain better agronomic characters and higher yield.
