“…Genotypic correlation (Table 2) revealed that the traits viz., number of bolls per plant (r=0.41), boll weight (r=0.57), number of seeds per boll (r=0.35), upper half mean length (r=0.53), fibre strength (r=0.37) and elongation percentage (r=0.34) displayed highly significant positive association with seed cotton yield, while the number of locules (r=-0.39) exhibited a highly significant negative correlation with seed cotton yield. Similar results were also reported by number of researchers (Satish et al 2020, Manonmani et al 2019, Chaudhari et al 2017, Farooq et al2014and Rahman et al 2013. In terms of inter-relationship among component traits, boll weight was reported to have a highly significant positive association with plant height (r=0.36), number of bolls per plant (r=0.39), number of seeds per boll (r=0.30), upper half mean length (r=0.58), fibre strength (r=0.42), fibre fineness (r=0.25) and elongation percentage (r=0.40), whereas the association of boll weight was negative with the number of locules per boll (r=-0.37).…”

“…The number of locules per boll (r=-0.28) displayed a significant negative association with seed cotton yield. Previous studies reported by Satish et al 2020 for boll weight, number of bolls per plant; Amelin et al 2020 for number of bolls per plant, fibre length; and Rai and Sangwan. 2020 for number of bolls per plant, boll weight, number of seeds per boll for association with seed cotton yield.…”

Background: Gossypium hirsutum, the most widely cultivated crop in the world has concurrent importance for both fibre quality and yield. Polygenes regulate cotton output and a variety of factors affect the characteristic. As a result, it is essential to have thorough knowledge of the relationships between different component traits and fibre quality. Thus, the aim of the study was framed to know about the correlation along with cause-and-effect relationship among the economic traits. Mathod: Eight parents and 56 hybrids made up the experimental sample for our study, which were evaluated for 18 economically significant traits. The study was conducted at Department of Cotton, Tamil Nadu Agricultural University, Coimbatore, in 2021-2022. Results: Analysis of variance was highly significant for all the traits studied. The result of correlation revealed that the traits viz., number of bolls per plant, boll weight, number of seeds per boll, upper half mean length and fibre strength had a high magnitude of positive correlation with seed cotton yield at both genotypic and phenotypic levels. Path analysis represented the direct effects of upper half mean length, uniformity index, number of bolls per plant, number of seeds per boll and fibre strength on seed cotton yield. Hence, these traits can be used as selection criteria for yield improvement in cotton.

The study investigates the technological characteristics of some Egyptian cotton varieties, under planting seasons, location, and their interactions. It aims to evaluate how variations in cultivation locations and seasons impact the observed differences in fiber attributes, as well as how the studied varieties adapt to diverse environmental conditions. The study also investigates the interaction between different growing seasons and locations and its effects on the varieties under scrutiny. A randomized block design (RCBD) with four replications was used during two seasons (2018 and 2019) at multiple locations across Egypt, including El-

The present investigation on correlation and path analysis studies helps to study the relationship among the yield and yield contributing traits along with the quality parameters. The observations were taken in the F1 population of 35 hybrids along with lines (7 lines) and testers (5 testers) for the traits viz. plant height (cm), number of sympodial branches per plant, the number of bolls per plant, boll weight (g), lint index (g), single cotton yield per plant (g), ginning outturn (%), upper half mean length (cm), elongation percent (%) and micronaire value (µg per inch). The results revealed that seed cotton yield per plant had strong and positive association with the traits namely number of sympodial branches per plant (0.646), number of bolls (0.633) and boll weight (0.652). Path analysis study revealed that number of sympodial branches per plant (1.5396), boll weight (0.6285), lint index (1.3526) and upper half mean length (0.3392) had high direct positive effects on single plant yield and indirect very high positive effects through the traits viz., number of sympodial branches per plant via., number of bolls per plant (1.5125) and boll weight (1.0121). Hence selection based on these traits that are positively associated and direct positive effect with the yield would produce the best outcome in the genotypes in further breeding programmes.
