Laboratory Tests Designed to Improve Cotton Planting Seed Quality

摘要

A number of representative seed lots of both upland and Pima cotton cultivars and experimental strains have been evaluated utilizing two instruments which measure relative seed coat strength. Seed coat strength was found to have a strong genetic component of determination, with relatively minor influence of environment and year of production being observed Greater seed coat strengths should contribute to the relative resistance to seed damage and cracking during picking ginning and conditioning operations. It may be possible to incorporate this trait into cotton cultivars by mass selection techniques.
