“…boll weight (H 2 = 0.96) and positive significant correlations (r = 0.476) with seedcotton yield. Numerous other researchers also reported positive genotypic associations between seedcotton yield and boll weight (Ahmed et al, 2008;Ismail & Al-Enani, 1986;Khan, 2003;Killi, 1995). Boll weight is the second most important trait influencing yield after bolls per plant (Gul et al, 2016).…”

Cotton (Gossypium hirsutum L.) lint yield and fiber quality are associated with various yield components. Research efforts addressing intra‐boll yield component contributors to lint production boll−1 are limited. Thus, a study was conducted in Tifton, Georgia with the objectives to quantify the contributions of intra‐boll yield components to lint production boll−1 and to identify yield components most strongly associated with lint production boll−1 in advanced breeding lines of upland cotton. Data collected included intra‐boll yield components and fiber quality parameters. A strong association was observed between lint production boll−1 and seedcotton weight boll−1 (r = 0.896) compared to lint production boll−1 and lint percent (LP, r = 0.574). For breeding lines with maximum lint weight boll−1, the contribution of seedcotton weight and LP ranged from 0.17 to 0.36 g boll−1 and 0.22 to 0.24 g boll−1, respectively, suggesting a relatively greater influence of seedcotton weight boll−1 on lint weight boll−1. Lint production boll−1 can be expressed as the product of seeds per boll, seed surface area, fiber density (FD), and individual fiber weight (IFW). IFW was the greatest contributor to lint production boll−1 for seven breeding lines and FD for nine breeding lines. A strong positive association was observed between lint production boll−1 and IFW (r = 0.656, p < 0.001); however, no significant association between lint weight boll−1 and FD suggesting a relatively greater influence of IFW on lint weight boll−1. Our work provides future direction aimed at improving lint yields through the selection of various yield components.

“…In this respect, El-Shaer et al (1984), Seyam et al (1984), Ismail and Al-Enani (1986) and El-Beily et al (1996) used the technique of stepwise multiple regression and correlation analysis for assessing the relationships between yield and its components. Moreover, Badr et al (2001), Hassan and Abdel-Aziz (2004) and Saeed et al (2008) on Egyptian cotton found significant correlation among earliness measurements i.e.…”

The present experiments were carried out at the Farm of the Faculty of Agriculture, El Fayoum University, in the summer seasons of 2010 and 2011 in a split plot design with five replicates, to investigate the effects of different sowing times, as an indication of different climatic environments i.e. micro-environments on earliness, yield and its components in some Egyptian genotypes.The obtained results indicated that the studied plant characters were significantly affected by microenvironments. However, its effect was not observed in some earliness measurements i.e. node number of the first sympodium, the period between the first bud and the first flower appearance, the period between the first flower appearance and the first boll opening and mean maturity date. Early sowing recorded the highest values of the studied characters. While, delayed sowing to the 1 st of April significantly decreased the values of the characters. Significant differences among varieties were found in all the studied traits over the three environments except the period among the first bud initiation and the first flower appearance and the period between the first flower appearance and the first boll opening. Giza 90 gave the highest seed and lint cotton yields. The results obtained clearly indicated that the treatment combination comprising early time on the first of March with the variety Giza 90 proved to gave the highest values of seed and lint cotton yields.It could be concluded that earliness traits were able to result in a linear regression model for all the five tested genotypes. At least two of these traits were included in the yield per feddan model of the five varieties. Consequently, this way of estimating earliness could be favored over the other methods used regardless of the variety studied.
