A successful cross fertilization involving two different species implies that a chain of reproductive process takes place unhampered after pollination. The coordination and interaction between genes or gene complexes in the pollen parent and matching gene or gene complexes in the pistil parent should be hormonious. Understanding of pollen tube growth and pollen attrition is revealed from the st...
به منظور آگاهی از میزان تنوع در ژنوتیپ های مختلف آپلند(gossypium hirsutum) در ایران، 35 ژنوتیپ مختلف شامل ارقام وارداتی، دورگ و موتانت موجود در موسسه تحقیقات پنبه ایران در سال های 1376 و 1377 در گرگان مورد ارزیابی قرار گرفتند. بررسی صفات مرفولوژیکی و کمی، تنوع بسیار خوبی را در بین ژنوتیپ های مورد مطالعه نشان دادند از 15 صفت اندازه گیری شده، 12 صفت در سال 1376 و 11 صفت در سال 1377 دارای اختلاف م...
Cotton is one of the most economically important fiber crop plants worldwide. The genus Gossypium contains a single allotetraploid group (AD) and eight diploid genome groups (A-G and K). However, the evolution of repeat sequences in the chloroplast genomes and the phylogenetic relationships of Gossypium species are unclear. Thus, we determined the variations in the repeat sequences and the evol...
MBI9915 is an introgression cotton line with excellent fiber quality. It was obtained by advanced backcrossing and continuous inbreeding from an interspecific cross between the upland cotton (Gossypium hirsutum) cultivar CCRI36 as the recurrent parent and the sea island cotton (G. barbadense) cultivar Hai1, as the donor parent. To study the genetic effects of the introgressed chromosome segment...
ILD Gossypium anomalum Wawrs. and Peyr. among Gossypium species whas anomalous petal spot inheritance. Its petal spot involves two independently inherited genes; a ghost spot gene interacts with a spotless gene making a large anthocyanin area at the base of a petal (SILOW 1941). In the two cultivated Asiatic diploid species red petal spot involves three closely linked genesmargin. ghost spot, a...
BACKGROUND Upland cotton, Gossypium hirsutum L., is one of the world's most important economic crops. In the absence of the entire genomic sequence, a large number of expressed sequence tag (EST) resources of upland cotton have been generated and used in several studies. However, information about the flower development of this species is rare. METHODOLOGY/PRINCIPAL FINDINGS To clarify the mo...
