“…Recently, attempts to unravel events that have occurred between annual Helianthus and cultivated sunflower have been studied using interspecific crosses (Kim and Rieseberg 1999;Burke et al 2004;Strasburg and Rieseberg 2008;Sujatha et al 2008;Heesacker et al 2009). Serieys (1987), Jan et al (2006), Christov et al (2009), andŠkorić et al (2010) reported many trait transfers from perennial Helianthus, just a few of molecular study has been published on the localization of introgression fragments between common sunflower and perennial Helianthus. In practice, lines carrying one or a few introgression fragments from diverse wild Helianthus have been produced without selection pressure, but only by screening segregating progeny for some agronomic traits such as seed size and oil yield (Serieys 1987).…”

“…H. mollis displays resistance to most sunflower pathogens (Atlagić et al 1995) and to the broomrape parasite (Orobanche cumana Wallr.) as all perennial Helianthus species (Jan and Fernandez-Martinez 2002;Christov et al 2009). Thus, sexual combination of sunflower and H. mollis could lead to plants that combine the most valuable traits of each species such as one stem and all agronomic traits from sunflower, with sessile leaves or shorter petioles, as disease tolerance or resistance from H. mollis.…”

Common sunflower (i.e., Helianthus annuus) is occasionally crossed with other Helianthus species to gain favourable agronomic traits. An interspecific cross between H. annuus and Helianthus mollis was used to examine events that occurred during the five first generations. First generation hybrid plants were verified using GISH, and F 1 hybrid (#17) was back-crossed to common sunflower to obtain BC 1 (#4) and BC 2 (#21). Some BC 2 progeny possessed new traits, i.e., compact (Compact plant architecture is due to short inter-node length, short petiole length and short leaf lamina length) architecture without and with corrugated leaves, which were not observed in the parents. These traits were selected for and fixed after the BC 2 -S 3 (#18) to produce a H. mollis introgression line (namely HM374). Although the size of the population was small, we tentatively construct a genetic map using data from the BC 2 generation. Two linkage groups were identified carrying H. mollis specific AFLP markers that were associated with compact plant architecture, and one unlinked marker was shown to explain variation for the corrugated leaves. Introgression line HM374 was used to test the inheritance of compact plant architecture in a cross with an elite high oleic line, OL75HO. Microsatellite (SSR) markers were used to genotype F 1 and F 2 offspring's. Our data suggested that the line HM374 was still heterozygous for introgression after eight generations. HM374 displays new architecture traits (i.e. compact architecture with or without corrugated leaves) and carries H. mollis fragments anchored on LG1 and LG11 of sunflower public map.

Crop wild relatives (CWR) are valuable sources of variation for the genetic improvement of crops. Mexico is an important center of diversity of crops and CWR. However, this diversity is threatened by climate change, habitat degradation, increasing human population, among other factors. Given the large number of CWR, the creation of a CWR inventory is the starting point for the development of a national CWR conservation strategy. The process for the preparation of a national CWR inventory for Mexico consisted of (i) producing a list of national crop species, (ii) matching the crop genera with the list of national flora to produce a CWR checklist, and (iii) prioritizing the CWR checklist according to a series of selection criteria and using a ranking system. The selection criteria included the economic value of the related crop, the potential for crop improvement, food intake, threat status, geographical distribution, and crop use. Applying these criteria, 310 prioritized CWR taxa were selected (~2% of the national CWR diversity), integrating the national CWR inventory. They are mostly related to food crops of national but also global importance, such as maize (Zea mays L.), common bean (Phaseolus vulgaris L.), chili pepper (Capsicum annuum L.), squash (Cucurbita spp.), potato (Solanum tuberosum L.), cassava (Manihot esculenta Crantz), and sweet potato [Ipomoea batatas (L.) Lam.]. Approximately 31% of the taxa are endemic to Mexico. The inventory will help to develop in situ and ex situ conservation plans as part of a national CWR conservation strategy.

“…Different ways for controlling parasite were tested (different methods of soil cultivation, herbicides use, biological agents, etc. ), which gave results (Christov et al, 2009). The resistance to races (A, B, C, D and E) is controlled by single dominant genes (Or 1 , Or 2 , Or 3 , Or 4 and Or 5 ).…”

Broomrape (Orobanche cumana Wallr.) presents a serious problem in sunflower production in a number of countries, it reduces sunflower seed yield and negatively affects other sunflower traits in sunflower production. Continued work on creating new sunflower hybrids resistant to broomrape requires testing of breeding materials in both field conditions and controlled conditions of a greenhouse. The best solution is to do the testing simultaneously in order to verify the congruence of the evaluation of the broomrape resistance achieved by these two methods. The screening of chosen new 15 sunflower hybrids for broomrape resistance was done in 2009 and 2010 in infected field on two locations in Vojvodina Province and in 2010 in greenhouse. Both field and the greenhouse tests rated the hybrids exclusively on the basis of presence or absence of the parasite. The infection of hybrids with broomrape has shown that out of 15 hybrids tested, 9 hybrids were resistant. These hybrids were fully resistant in both years in field conditions and controlled greenhouse conditions during one year. Fully resistant hybrids in field conditions and in greenhouse conditions NS-H-6385 and NS-H-6396 had significantly higher seed yield, seed oil content and oil yield in relation to standard.
