“…Further, they can tolerate a delayed chemical spray interval and may contribute to significant reduction in chemical inputs. Such a slower disease progress was earlier observed in peanut against GBNV (Kesmala, and Kesmala et al., ) and TSWV (Nascimento et al., ), in cucumber against cucumber mosaic virus (Munshi et al., ) and in okra against okra yellow vein mosaic virus (Seth, Chattopadhyay, Dutta, Hazra, & Singh, ). Further, in the experiment it was also observed that the P1, F 1 , F 2 and BC1 showed a higher plant survival and vine length compared to P2, BC2 and checks for both the crosses.…”

An experiment was conducted to study the genetics and nature of gene action of resistance to watermelon bud necrosis orthotospovirus (WBNV) in watermelon. The experimental materials comprised of two resistant (BIL‐53 and IIHR‐19) and one susceptible (IIHR‐140) parents. Each of the resistant parents was crossed with the susceptible parent to develop six generations (P1, P2, F1, F2, BC1 and BC2) to study genetics. The results of segregation in F2 and backcross progenies suggested that resistance is governed by a major dominant gene along with other background minor genes in both the crosses. BIL‐53 was found to possess higher degree of resistance with simple inheritance and hence may be of interest to breeders. Simple selection can be effective for improving the trait in the cross BIL‐53 × IIHR‐140 as additive gene action is prevalent.

“…Inheritance studies of Seth et al . (2017) and Sharma and Dhillon (1983) concluded that the inheritance of OYVMV resistance in okra is controlled by two dominant complementary genes. Jambhale and Nerkar (1981) reported that resistance to OYVMV is controlled by a single dominant gene.…”

“…Ali et al (2000) studied the inheritance of OYVMV tolerance using inter-varietal crosses and revealed that it is a quantitative trait involving two major gene effects and the tolerance depends on gene dosage with incomplete dominant gene action. Inheritance studies of Seth et al (2017) and Sharma and Dhillon (1983) concluded that the inheritance of OYVMV resistance in okra is controlled by two dominant complementary genes. Jambhale and Nerkar (1981) reported that resistance to OYVMV is controlled by a single dominant gene.…”

“…Various types of inheritance patterns for genetic resistance to OYVMV disease have been reported in varieties of A. esculentus and wild species. Some scientists have reported that the resistance is controlled by two dominant complementary genes (Thakur 1976;Sharma and Dhillon 1983;Sharma and Sharma 1984;Seth et al, 2017) but others have reported that a single dominant gene (Jambhale and Nerkar, 1981;Senjam et al, 2018) or two recessive genes (Singh et al, 1962) are responsible for the resistance. The current study was conducted to investigate the genetics of wild relative of okra A. angulosus which is available in Sri Lanka against the OYVMV disease to explore the possibility of utilizing A. angulosus as a resistant source of OYVMV disease in future okra breeding programmes.…”

Wild relative of okra, Abelmoschus angulosus Wall. ex Wight & Arn. was identified as a resistant germplasm for Okra Yellow Vein Mosaic Virus (OYVMV) which is the devastating disease for okra cultivation in Sri Lanka. The mode of resistance of OYVMV in A. angulosus was studied with the aim of tagging responsible genes for the disease resistance. Wide hybridization was performed between A. angulosus and highly virus susceptible A. esculentus variety, MI-7. Very poor seed setting was observed in F1 and F2 generations due to post zygotic abortion. Disease screening was carried out using F1 and F2:3 populations along with parents in the field under induced disease pressure. Disease severity index and area under disease progress curve were calculated to measure disease severity. Number of genes segregating for OYVMV disease resistance was calculated for the F2:3 generation. Modified Wright's formula was used to estimate the effective gene number and mode of inheritance by a quantitative method. A χ2 test was performed for qualitative analysis. Plants of A. angulosus were totally free of virus incidence while 100% disease incidence was observed in the variety MI-7. F2:3 population showed between and within progeny segregation for disease incidence. Results indicated that the disease susceptibility was dominant over resistance. χ2 analysis revealed that the segregation of disease severity was significantly fit to the gene model of 9:6:1 (χ2 = 0.1757 at P ≤ 0.05) suggesting the disease resistance in A. angulosus is governing by two recessive genes in an additive manner. Result was confirmed by the quantitative analysis.
