مطالعه روابط بین عملکرد و اجزاء عملکرد پنبه (Gossypium hirsutum L.) در شرایط شور

To study yield, yield component and some morphological traits in cotton, six parents with 15 hybrids (totally 21 genotypes) were evaluated using a randomized complete block design with three replications at a salty farm Bandar Torkaman area in 2005. Nine traits were measured including the percentage of germination, plant height, number of monopodial branches, length of monopodial branches, number of sympodial branches, length of sympodial branches, boll number, boll weight and yield. Analysis of variance and mean comparison show highly significant differences among the genotypes for the traits, such as plant height, length of monopodial branches, boll number, boll weight and yield. Also results showed that a positive and significant simple correlation between yield and germination, plant height, number and length of sympodial branches and boll number but non significant for number and length of monopodial branches and boll weight.
