“…Among numerous obstacles to a successful seed set, the most significant feature observed was the presence of a physical barrier of multiple tissues between the male (pollen) and female (pistil) gametophytes leading to a low seed and fruit set in Abelmoschus crosses involving the wild relatives. Earlier studies reported that the hybridisation between A. esculentus and its wild species resulted in a low fruit and seed set along with sterile and shrivelled seeds (Ustinova, 1949;Pal et al, 1952;Jambhale & Nerkar, 1981). In the present study, field data substantiated with comparative pollenpistil interaction studies were conducted at various intervals by means of fluorescence microscopy and SEM.…”

“…Earlier studies and efforts to bring useful genes from wild okra were only partially successful due to presence of unidentified pre-and post-fertilisation barriers to gene flow in this genus (Pal et al, 1952;Kuwada, 1957Kuwada, , 1966Siemonsma, 1982). However, there are highly sporadic attempts aimed at interspecific hybridisations among A. esculentus and its wild relatives so far (Jambhale & Nerkar, 1981;Nerkar, 1991;Tyagi, 2002).…”

Pollen-pistil interactions play a crucial role in successful introgressions for desirable traits and are often restricted by presence of pre-or post-fertilisation barriers in various crops. Importance of wild germplasm of Abelmoschus (Malvaceae) as source of genes for biotic and abiotic stress resistance in crop improvement programmes have long been recognised by breeders. In the present study, behaviour of pollen germination and pollen tube growth were evaluated with respect to the seed set among four species of Abelmoschus. Alien pollen tubes showed significantly high growth inhibition in okra (A. esculentus) pistils and seldom penetrated the stigma. Pollen tube growth was normal in A. esculentus × A. caillei and its reciprocal cross, indicating the potential for its use in genetic improvement. Delayed pollen tube growth along with other structural abnormalities like twisting, swelling, high branching, bi-furcated tip and variation in callose form (reverse orientation and irregularity in callose plugs along the pollen tube) were frequently noticed in the interspecific crosses. The results indicated that the crosses A. manihot subsp. tetraphyllus var. pungens × A. esculentus had high incompatibility, while A. manihot subsp. tetraphyllus var. tetraphyllus × A. esculentus were partially compatible and A. esculentus × A. caillei were fully compatible.

“…many reports showed that YVMD resistance is controlled by two dominant complementary genes (Sharma and Sharma 1984a), on other hand many showed that there is a single dominant gene (Jambhale and Nerkar 1981) or two recessive genes (Singh et al, 1962) responsible governing the resistance against to YVMD. Dhankhar et al, (2005) concluded the hypothesis that two complementary dominant genes were involved in governing the resistance to yellow vein mosaic virus disease in okra.…”

“…Among these viruses, YVMV transmitted by whiteflies, is the most pressing plant protection problem universally faced by all okra growers [40] [41] causes significant losses in the okra production. Some attempts had been made by several workers to reduce to disease through the vector control [42]- [45] and also through the breeding strategies [46] [47]. Resistance breeding for YVMV to develop YVMV resistant variety is essential for stable and sustainable okra production.…”

Okra (Abelmoschus esculentus L. Moench) is a traditional pod vegetable widely grown in low, medium and high-input systems for domestic and export markets. The economic and ecological sustainability of okra in these systems is under question because of the low-yielding potential, suboptimal pod quality and susceptibility to biotic and biotic stresses especially the yellow vein mosaic virus (YVMV) of the traditionally cultivated open-pollinated varieties (OPVs) and landraces. Development and use of improved varieties with high yield potential, superior pod quality and resistance to YVMV play an important role in bringing sustainability of okra in these systems. Fifteen single cross hybrids developed by crossing six newly developed inbred lines (RNOYR-14, RNOYR-15, RNOYR-16, RNOYR-17, RNOYR-18 and RNOYR-24), in half-diallel fashion during rainy season 2012, were evaluated along with three local hybrid checks [No. 64 (Mahyco), Avantika (228) (Bioseed) and Shakti (Nunhems)], one OPV check (Arka Anamika) and one OPV cross check for YVMV susceptibility (Pusa Sawani) in a randomized complete block design with three replications during summer 2013 at the Vegetable Research Station, Hyderabad for studying their yield potential, pod quality and resistance to YVMV. All of the 15 single cross hybrids were resistant to YVMV with 0% incidence as against 100% incidence in OPV checks Arka Anamika and Pusa Sawani. On the basis of mean performance, three crosses RNOYR-15 × RNOYR-16, RNOYR-16 × RNOYR-17 and RNOYR-17 × RNOYR-18 were of significantly higher yield potential than the standard check "No. 64", but of comparable yield potential with other checks "Avantika" and "Shakti". In addition, these three crosses also of superior pod quality could be exploited for development of commercial hybrid okra. These hybrids would be advantageous for production and quality improvement, trade
