“…The results are in agreement with Pushpam and Raveendran (2006). Kaur et al, (2016) reported that intermediate leaf shape and size in hybrids between Gossypium hirsutum and Gossypium armourianum. Similarly, theintermediate expression of plant growth habit, leaf size and petal colour have reported in other interspecific hybrids such as between Gossypium davidsonii x Gossypium anomalum, Gossypium hirsutum x Gossypium arboreum (Ahmad et al, 2011;Tahir et al, 2011), Gossypium herbaceum x Gossypium australe (Liu et al, 2015) and Gossypium arboreum x Gossypium thurberi (Kale et al, 2007).…”

Low percentage of pollen fertility was observed in Gossypium hirsutum x Gossypium armourianum hybrid (9.04 %) and Gossypium hirsutum x Gossypium raimondii hybrids (9.67%) by Pushpam and Raveendran (2006) and Gossypium hirsutum x Gossypium armourianum hybrid (2.19 %) by Kaur et al, (2016). Pollen size of F 1 hybrids also showed more variation when compared to parents and significant differences were observed.…”

Interspecific triploid hybrids were developed between tetraploid cultivated species Gossypium barbadense cv. Suvin and TCB 37 and diploid wild species Gossypium armourianum. The F 1 hybridity was confirmed by morphological, cytological and molecular approaches. The ploidy level of interspecific F 1 hybrid was triploid and completely male sterile. Female parents Suvin and TCB 37 had erect growth habit, yellow petals, palmate leaves, green stem, thick and prominent leaf veins, but Suvin had dense yellow anthers while TCB 37 was with dense creamy anthers whereas male parent has a spreading growth habit, yellow petals, cordate leaves, reddish green stem, medium dense yellow anthers, thin leaf veins, protruded stigma and glabrous plant body. The growth habit, petal colour, leaf shape and size of interspecific F 1 hybrid were intermediate. Plant stem colour, hairyness, leaf pubescence and anther colour of Gossypium armourianum were observed to be dominant as hybrid fully resembled Gossypium armourianum for these characters. Petal spot was observed in both male and female parents but F 1 hybrids had different intensity of petal spot in their petals. Variable expression of petal spot, anther colour and filament colour was observed in the F 1 hybrids. Gossypium barbadense cv. Suvin and TCB 37 had 52 chromosomes, Gossypium armourianum had 26 chromosomes and the interspecific F 1 was with 39 chromosomes. Significant differences were observed between pollen size, pollen fertility of parents and their hybrids. The F 1 interspecific hybrid having more than 97% of sterile pollen grains. Out of 6 polymorphic SSR markers between parents, 3 markers unambiguously confirmed the hybrid status of interspecific hybrid. This hybrid may serve as useful genetic resource for the transfer of jassid resistance gene to Gossypium barbadense cultivars.

“…However, the hybrid had both colourless and coloured connectives present in the different flower and also in same flower. Previous researchers hypothesized that the varied expression may be caused by epigenetic changes in the DNA (Kaur et al, 2016). Mahalingam et al 2020 has also reported similar results regarding the colour of connective tissue.…”

“…The petal spot, a crucial morphological indicator for confirming hybridity, exhibited variable expression strength. On the other hand, intrahirsutum crosses between wild type and mutant strains revealed complete dominance of the petal spot (Ahuja and Dhayal, 2007).Other researchers have noted that G. hirsutum x G. arboreum hybrids had less colour intensity in their petal spots than F1hybrids (Tahir et al, 2011;Ahmad et al, 2011, Kaur et al, 2016. Mixed variable expression of petal spots was also observed in G. hirsutum and G. barbadense interspecific hybrids grown in India (Kauret al, 2016).The probable reason for the expression of petal spot might be because of variable expressivity for the trait.…”

“…All four cultivated species are grown commercially in India (Blaise and Kranthi, 2019). Among the D genome diploid wild species counting to 13 in number, G. armourianum, is resilient towards a variety of insects, pests, and diseases, especially hazardous pink bollworms and jassid (Narayanan et al, 2014;Pushpam and Raveendran, 2006;Kaur et al, 2016). Numerous instances have demonstrated the significance of cultivated as well as wild Gossypium diploid genomes as reservoirs of commercially valuable genes (Mehetre et al, 2002;Kebede et al, 2007).…”

Wild species constitute a source of valuable genes for many adverse climatic conditions, disease and pests. To match up the level of quick depleting insect pest and disease resistance and fast evolving pests, it is the urge of the hour to broaden the resistance base. In order to achieve this goal in cotton, wide hybridization was performed between G. hirsutum (AADD) cv. MCU5, CO14 and CO17, and G. armourianum and interspecific hybrids developed were characterized for several morphological characters for obtaining an idea about the status of the various traits. Interspecific hybrid developed with all three G. hirsutum varieties are potential lines for future introgression programs of insect and disease resistance along with other useful traits. The F1 hybrid displayed intermediate expression for most of the traits. Traits like colour of the stem, leaf colour, position of stigma, nectarines of hybrid completely resembled wild parent-and are considered as dominant in expression. The petal spot was present in the hybrid similar to that wild parent, unlike the cultivated parent; this appeared with different levels of intensity in F1 along with other characters like colour of the anther, and filament colour. Hybrids had profuse flowering throughout the year with low pollen load and pollen of variable shape and size expressing sterility to partial fertility. Noteworthy differentiation was seen between the leaf size and size of other plant parts of the hybrid.
