“…Uniform fast seed germination and early seedling vigor are important traits for seedling establishment. However, most rice varieties are severely affected during early seedling growth when the temperature falls below 17°C (Andaya and Mackill 2003a;Lou et al 2007;Ranawake et al 2014;Singh et al 2016). For better and more stable stand establishment, especially under direct-seeding conditions in temperate and sub-temperate regions, cold tolerance at germination is a pre-requisite (Teng et al 2001;Cruz and Milach 2004;Wang et al 2016a).…”

“…Conventional plant breeding has achieved partial success in developing LTS-tolerant crops because of the complexity of stress tolerance traits, the low genetic variance of yield-attributing components under stress conditions, and the lack of efficient selection criteria (Sanghera et al 2011;Singh et al 2016). Therefore, it is imperative to find complementary strategies to conventional breeding methodologies such as molecular marker technologies, linkage maps, and advanced genomic tools to develop LTS-tolerant rice cultivars.…”

“…It will be difficult to increase rice production to satisfy this demand because land and water resources become more scarce with increasing competition from fast-growing non-farming sectors [3]. Especially, rice crop is a heat and water-loving crop [4], then, sometimes the rice badly suffers from cold stress during the seedling stage when it is grown in winter environment [5]. Therefore, monitoring the global productivity of rice is one of the adequate solutions to meet the demand for rice.…”

“…Увеличение объема популяции не гарантирует повышения эффективности маркирования. Например, в популяции F 2 при объеме выборки 2810 образцов авторами был выявлен один локус, тогда как в популяции из 191 RILs -15 локусов (36,37). Очень важно подобрать в качестве родительских форм максимально контрастные образцы.…”

“…О локусах qCTS-9 и qCTS-12 со значительным фенотипическим эффектом (от 5,5 до 22,4 %) на 9-й и 12-й хромосомах ранее сообщали китайские и индийские ученые, работавшие преимущественно с популяциями на основе межподвидовых гибридов (34,35). На 5-й и 4-й хромосомах у подвида indica также было обнаружено от одного до трех локусов, влияющих на формирование признаков (25,37). Выявляемые наиболее часто локусы на 1-й, 2-й, 8й хромосомах не были связаны с полиморфизмом по изучаемому признаку в популяции отечественных образцов риса, для которых многие локусы, сцепленные с ростовыми параметрами, были мономорфны, что объясняется продолжительной целенаправленной селекцией (33).…”
