“…Results from the paired samples t-test indicated that there was no significant difference (p≥0.05) between the LD 50 (herbicide rate that caused 50% mortality) or GR 50 (herbicide rate that caused 50% reduction in shoot growth) values of susceptible weedy rice (S-WR) and rice cultivar MR220, respectively for all tested herbicides (Tables 2 and 3). Conventional rice and weedy rice generally have similar responses to imidazolinone herbicides as was reported also in Italy, involving the conventional rice cultivar 'Claudio' (Kaloumenos et al, 2013). In the USA, Kuk et al (2008) reported that the conventional cultivars Drew, Bengal, Dongjin, and Wells were equally susceptible to imazethapyr as the standard susceptible weedy rice accession 82.…”

“…The R-WR populations that evolved via gene flow are expected to have the same resistance level as the Clearfield ® rice cultivar that was involved in the hybridization process, upon reaching a homozygous state. The study by Kaloumenos et al (2013) demonstrated this, wherein the weedy rice outcrosses homozygous for the resistance-conferring Ser 653 Asn mutation in the acetolactate synthase (ALS) gene were as resistance as the Clearfield ® rice cultivar that donated the resistance trait. In the present study, the Malaysian CL rice was 18-to 32-fold more tolerant to OnDuty ® than the S-WR based on LD 50 and GR 50 values (Tables 2 and 3).…”

“…However, the evolution of herbicide-resistant weedy rice has occurred faster via gene flow than via selection of de novo resistance-conferring mutation(s) in the USA (Zhang et al, 2006;Shivrain et al, 2009b), Brazil (Roso et al, 2010), Colombia (Gressel and Valverde, 2009), Costa Rica (Valverde, 2005(Valverde, , 2007, Italy (Busconi et al, 2012), Greece (Kaloumenos et al, 2013) and Uruguay (Sudianto et al, 2013). The R-WR populations that evolved via gene flow are expected to have the same resistance level as the Clearfield ® rice cultivar that was involved in the hybridization process, upon reaching a homozygous state.…”

Planta Daninha 2018; v36:e018182239 DILIPKUMAR, M. et al. Cross-resistance to imazapic and imazapyr in a weedy rice (Oryza sativa) biotype found in Malaysia 1 151103-PD-2016 (9 páginas) PROVA GRÁFICA ABSTRACT -The Clearfield ® rice production system is an effective management tool for weedy rice and other weeds in the direct-seeded rice culture. However, if farmers cultivating the Clearfield ® rice disregard stewardship recommendations, the industry could face a problem of herbicide-resistant weedy rice which would occur through the selection of outcrosses. This study aimed to confirm imidazolinoneresistant weedy rice in Malaysia. The resistant weedy rice (R-WR) was found to be 67 fold more resistant to OnDuty ® (premix of imazapic and imazapyr) than the susceptible weedy rice (S-WR) based on the GR 50 values (rate that causes 50% inhibition of shoot growth). The Clearfield ® rice cultivar was 32-fold more tolerant to OnDuty ® than the S-WR. Furthermore, the R-WR was 54 and 89 fold more resistant to imazapic and imazapyr applied separately than the S-WR, respectively. The Clearfield ® rice was 140-and 40-fold more tolerant to imazapic and imazapyr, respectively than the S-WR. The R-WR biotype was susceptible to non-selective herbicides glyphosate and glufosinate, as well as the selective graminicide quizalofop. Oxadiazon controlled the R-WR biotype, but pretilachlor was ineffective. The present study documented the first case of weedy rice that was cross-resistant to imazapic and imazapyr in Malaysian Clearfield ® rice field.

A Mediterranean japonica rice (Oryza sativa) cultivar improvement through anther culture

Certified seed producers systematically select and propagate registered varieties year after year in order to maintain their uniformity and the original registered cultivar traits. However, natural mutations, spontaneous breeding between varieties and alien grain contamination can introduce undesirable variability. NRVC 980385 is a temperate japonica rice cultivar (Oryza sativa ssp. japonica) first registered in Spain in 2002. In 2005 certification tests detected a plot differing from the original traits in terms of uniformity and height suggesting the presence of a certain heterozygosis. This material was therefore seen as an opportunity to obtain newly stabilized doubled haploid (DH) lines which could compete in the Spanish short grain seed market. In this study, an in vitro anther culture protocol is defined which also covers the field tests selection to obtain four new, improved and stabilized DH derived lines ready to be registered for commercial proposes. This took just four years from the initial anther collection until new lines were grown in large scale field trials. Consequently, this protocol reduces the time for obtaining field assessed DH lines thereby having considerable advantages over other techniques by both maintaining the original registered cultivars and/or generating new derived varieties.

“…[94] Similar observations were made in Greece. [95] The consequence of poor HT crop stewardship is also a reality for an increasing number of growers in the Americas. [2] Prevention and mitigation strategies for HR weed management are generally understood, but there has been little will or reason to implement these strategies in spite of industry incentives.…”

Conventionally bred (CHT) and genetically modified herbicide-tolerant (GMHT) crops have changed weed management practices and made an important contribution to the global production of some commodity crops. However, a concern is that farm management practices associated with the cultivation of herbicide-tolerant (HT) crops further deplete farmland biodiversity and accelerate the evolution of herbicide-resistant (HR) weeds. Diversification in crop systems and weed management practices can enhance farmland biodiversity, and reduce the risk of weeds evolving herbicide resistance. Therefore, HT crops are most effective and sustainable as a component of an integrated weed management (IWM) system. IWM advocates the use of multiple effective strategies or tactics to manage weed populations in a manner that is economically and environmentally sound. In practice, however, the potential benefits of IWM with HT crops are seldom realized because a wide range of technical and socio-economic factors hamper the transition to IWM. Here, we discuss the major factors that limit the integration of HT crops and their associated farm management practices in IWM systems. Based on the experience gained in countries where CHT or GMHT crops are widely grown and the increased familiarity with their management, we propose five actions to facilitate the integration of HT crops in IWM systems within the European Union.ARTICLE HISTORY
