| Abstract | ||
| A field experiment was conducted during the summer season of 2024 in Al-Boaitha district, Anbar province, with the aim of determining the response of several genotypes of cotton to plant densities and its effect on some yield and components traits and fiber quality. The experiment was applied in split plot arrangement, according to the design of the randomized complete block design (RCBD), with three replications. The main plots included three of plant densities ( 33.333, 44.444, 66.666 Plant h-1 ) while the sub-plots included fifteen cotton genotypes ( Cocker 310, Lashata, ST- 468 , BA440 , FLASH , Cocker 310 X Lashata , Cocker 310 X ST-468 , Cocker 310 X BA440 , Cocker 310 X FLASH , Lashata X ST-468 , Lashata X BA440 , Lashata X FLASH , BA440 X ST-468 , FLASH X ST-468 and FLASH X BA440 ).The results showed that the Cocker 310 X ST-468 genotyp outperformed with the highest average of the studied traits plant height (156.50 cm ) and total number and opened bolls per plant ( 59.40 , 39.32 bolls plant-1 ) which reflected an increase in the individual and total seed cotton yield ( 3.735 tons ha-1) While the Lashata X ST-468 genotype gave the highest average of Upper half mean, the Cocker 310 X Lashata genotype showed the best Strenght 26.70 mm and 23.03 g/tex ) respectively. The increase in plant density led to an increase in the total seed cotton yield 3.972 tons ha-1,.. | ||
