“…In total, four crosses showed economic heterosis at a significant level against the superior check, i.e., JA-134, and these were L 14 × T 3 (12.94%) followed by L 5 × T 3 (11.95%), L 14 × T 2 (8.44%), and L 9 × T 3 (7.84%) (supplementary datasheet Table S2). A similar result was also reported for ashwagandha for its plant height and number of primary and secondary branches per plant [27]. A positive and significant heterosis for the number of secondary and tertiary roots per plant was exhibited by two hybrids against the magnitude of the mid-parental level (Table 5); furthermore, none of the crosses showed this against the better parent, whereas two hybrids against best check (JA-20), viz., L 12 × T 3 (10.30%) and L 5 × T 3 (8.93%), showed a significant heterosis.…”

“…In total, three crosses over the best check (JA-134), viz., L 14 × T 2 (15.30%) followed by L 5 × T 1 (13.68%) and L 5 × T 3 (7.52%), showed a significantly positive heterosis for the root diameter in the collar region (Table 6). The heterosis for the root diameter in the collar region was also reported earlier [27]. The desirable ashwagandha crop plant should have a superior root yield and heterosis in a positive direction.…”

Ashwagandha is an important, medicinal, less exploited crop and most of its cultivated varieties are local cultivars. Information related to ashwagandha’s genetic diversity is very limited. Hybrid vigor exploitation may be useful in breaking its yield barrier at a commercial scale. A total of 45 F1 crosses were produced during Kharif 2017-18 by using a line x tester matting design, which included three testers along with 15 lines. A total of 65 genotypes were grown in an RBD design, with three replications in three different environments during Kharif 2018-19, and observations were recorded for 11 different yield-attributing traits that were responsible for the estimation of the magnitude of the heterosis. An analysis of variance showed that a valuable amount of diversity existed in the breeding material. Based on the study, three promising crosses viz., UWS-305 × UWS-10, UWS-305 × RVA-100, and UWS-301 × RVA-100 were identified as superior heterotic materials for the root yield at harvest, whereas for the total alkaloid content, three excellent hybrids viz., UWS-309 × RVA-100, UWS-305 × RVA-100, and UWS-314 × RVA-100 were reported. Out of the above crosses, the cross-combination of UWS-305 × RVA-100 showed a significantly positive and useful heterosis on a pooled basis. Hence, the above crosses may be gainfully utilized in breeding programs for ashwagandha.

“…Twenty-five crosses out of the thirty-six crosses showed significance over the better parent for the trait number of seeds berry -1 . Among that, twenty-three crosses were The results derived from this study points towards the possibility of exploitation of heterosis in the ashwagandha germplasm for the improvement of root yield related traits which is in agreement with the finding of Patidar et al (1990), Arpan et al (2014) and Dhuri (2016). Accordign to previous reports the heterotic combinations for root yield is expected to show high total alkaloid content due to significant correlation (Kumar et al, 2011).…”

“…Highly significant positive heterotic crosses over the standard check include SKA 10×JA 20 (114.56%) and SKA 26×AWS 1 (92.12%). The number of secondary branches was found to be correlated with the root length, diameter and fresh weight as per the findings of Arpan et al (2014). Hence the significant heterosis for the number of secondary branches can take into account for the exploitation of hybrid vigour in the root traits as well.…”

A study was conducted was conducted to estimate the extent of heterosis for root yield and attributing traits in ashwagandha at the Botanical Garden, Department of Genetics and Plant Breeding, C. P. C. A, S. D. Agricultural University, Sardarkrushinagar, Gujarat, India. Thirty six hybrids were generated from the diallel mating design of 9 diverse parents during October 2018 – March 2019 (rabi season). Fourty five entries were evaluated in RBD with 3 replications during October 2019–March 2020 (rabi season) for the yield and attribuiting traits. The root traits are given more emphasis because of its economic value.All the forty-five genotypes exhibited moderate to good mean performance along with an adequate amount of variability among and between the parents and hybrids. Most of the hybrids showed highly significant better parent and standard heterosis in desirable direction for the traits considered. The hybrids like SKA 10×JA 20, JA 134×AWS 1, SKA 24×SKA 26, SKA 24×AWS 1, SKA 11×AWS 1, SKA 11×SKA 26 and JA 20×AWS 1 were with a markedly significant heterotic response for fresh root yield trait. The results also suggest that the cross JA 134×AWS 1is appropriate to exploit heterosis in root length, fresh root yield and dry root yield. Further evaluation and generation advancement of these successful crosses can derive transgressive segregants and hybrids with high yield potential for commercialization.

“…Out of 45 hybrids, positive and significant average heterosis for number of primary branches per plant were exhibited by 15 hybrids, whereas, helerobeltiosis shown by 4 crosses furthermore, in case of desirable economic heterosis, it was depicted by 7 hybrids with the highest value shown by L1 x T3 (11.72 %), ). Heterosis for the above mentioned traits has also been observed earlier (Arpan et al 2014).…”

In the present experiment, 45 F1 hybrids of Ashwagandha were included in relation to investigate extent of heterosis for dry root yield and its attributing characters. The pooled ANOVA depicted the valuable amount of diversity existed among genotypes for all the characters. The significant estimates of heterosis in desirable direction were recorded in 22 hybrids over the mid parent, six hybrids over the better parent and six hybrids against the superior check (JA-134) for dry root yield, out of which the cross, UWS-309 × RVA-100 exhibited highest useful heterosis (17.42 %) for dry root yield across the environments, hence, the cross may be gainfully utilized.
