“…About 25% of crosses recorded significant sca effects for plant height, head diameter and seed yield per plant which indicate the presence of epistasis. This result conforms with the earlier reports of Chandirakala et al (2016), Nichal et al (2017) Ghaffari and Shariati, (2018), Hilli et al (2020) and Karande et al (2020). Hence, these crosses may be exploited in the sunflower breeding programme for increasing seed yield and oil yield components.…”

A study was carried out to assess the combining ability of ten CMS lines with four testers using the line x tester method. Biometrical observations were taken for days to 50% flowering, plant height, head diameter, days to maturity, volume weight, hundred seed weight, seed yield /plant, oil content and oil yield/plant. Specific combing ability variance was greater than the general combining ability variance for all the characters which indicated that non-additive gene action played a major role in inheritance. The gca of parents were not in agreement with the per se performance for various traits. Hence, the selection of parents should be based on gca alone for a breeding programme. Three lines viz., COSF 12A, COSF 13A and CMS 207A, and tester IR 6 were identified as good general combiners for seed and oil yield. Among the hybrids generated using good general combiners, COSF 13A x IR 6 had the additive type of gene action for seed and oil yield per plant. In general, most of the crosses had non-significant sca for oil yield per plant and oil content which indicated the presence of an additive type of gene action. Hence, the selection of good general combiners for oil content, seed and oil yield will help to evolve high oil yielding hybrids in sunflowers.

“…Among the hybrids, nine hybrids recorded significant and negative sca values for plant height. A similar finding was reported by Karande et al (2020). Out of 40 hybrids, four hybrids (COSF 10A x CSFI 99, CMS 112A x CSFI 99, CMS207A x LTRR341 and ARM248A…”

“…Hybrid breeding in Sunflower was started economically after the discovery of CMS by Leclercq in 1960 and restorer genes by Kinman in 1970 (Fick and Miller, 1997). and currently, hybrid breeding program is well developed (Chandirakala et al,2016;Nichal et al, 2017;Ghaffari and Shariati, 2018;Hilli et al,2020;Karande et al, 2020).…”

The present study was aimed to assess the molecular genetic diversity in 14 parental lines (10 maintainers and 4 restorers) of sunflower crop using 51 SSR markers. A total of 147 alleles were produced with the range of 1-6 alleles per locus. The polymorphic information content (PIC) values ranged from 0.12(ORS1198 in LG5) to 0.74(ORS384 in LG15) with an average PIC of 0.51. A phylogenetic tree was constructed by neighbour-joining method which grouped the parents into four clusters. Among the maintainer and restorer combinations, the dissimilarity index was maximum between CMS 519B and CSFI 99 (0.67) which indicateed high divergence between them. Lower dissimilarity value was observed between RCR CMS 38B and LTRR 341 (0.40) suggested less divergence between them. Mahalanobis D 2 analysis was also carried out among the parental lines. The D 2 analysis grouped the parental lines into six clusters. Among them genotype pairs CMS104B vs RHA 1-1 and CSFI 99 vs LTRR341 had highest and lowest D 2 values respectively. Dissimilarity and D 2 values for parental combinations, mean performance, mid and better parental heterosis of 40 hybrids for yield and its component traits were subjected to simple correlation analysis. The D 2 analysis did not show any association with performance of hybrids. However, the dissimilarity values showed association with hybrid performance and heterosis for plant height and volume weight. Hence, the present study indicated that the selection of parental genotypes with high molecular diversity could result in improved performance of plant height and volume weight in sunflower hybrids. However further study is required with multi environment data sets.
