Abstract

Abstract

Field and greenhouse experiments were conducted on cotton (Gossypium hirsutum L.) lines with differing maturities to determine what factors of plant growth contributed to early crop maturity and how these factors were related. Earliness was measured in terms of flowering, boll setting, length of boll maturation, and crop maturity. Additional measurements included plant growth and dry weight partitioning, productivity, and agronomic performance. Plant maturity was determined by time of flowering and length of boll maturation. Lines with the earliest crop maturities produced the lowest yields per plant. Performance of individual early maturing lines, such as 6 M, with improved agronomic properties, demonstrated the ability to increase early crop maturity with improved yield.
