Drought resistance of various rice genetic background based on raised bed screening system
نویسندگان
چکیده
Drought is one of the major constraints rice production in Indonesia. Climate change increases risk drought incidences. The evaluation resisting genotypes available Indonesia would hopefully find and enhance such resistance which could be utilized to further tested releasing a variety or donor parent within drought-resistant breeding program. Raised bed system (RBS) relatively reliable method screen up generative growth phase. This research aimed 69 including 26 IRRI accession included 3000 genome sequencing projects, 29 elite lines, 6 old released variety, each susceptible resistant check raised screening system. trial was conducted RBS facility ICRR from January May 2017 following randomized complete block design two replications. materials were directly planted 10 hill row with planting space 20 cm x cm. result showed that HHZ5-SKI-9-3-0Kr-JK-IND IR64 Dro1 had good leaf drying rolling number field grain/panicle. IR84636-13-12-2-6-3-3-2-2-B, Inpari 18, Huanghuazhan highest total grains/plant. Some mechanism might found genotypes.

Genetic basis of drought resistance at reproductive stage in rice: separation of drought tolerance from drought avoidance.
Drought tolerance (DT) and drought avoidance (DA) are two major mechanisms in drought resistance of higher plants. In this study, the genetic bases of DT and DA at reproductive stage in rice were analyzed using a recombinant inbred line population from a cross between an indica lowland and a tropical japonica upland cultivar. The plants were grown individually in PVC pipes and two cycles of dro...
متن کاملGenetic determination of the enhanced drought resistance of rice maintainer HuHan2B by pedigree breeding
The ongoing deficit of fresh water resource in rice growing regions has made the selection of water-saving and drought-resistance rice (WDR) a crucial factor in developing sustainable cultivation. HuHan2B, a new japonica maintainer for WDR breeding, had the same yield potential as recurrent parent HanFengB but showed improved drought resistance in fields. We investigated the genomic content acc...
متن کاملInvolvement of polyamines in the drought resistance of rice.
This study investigated whether and how polyamines (PAs) in rice (Oryza sativa L.) plants are involved in drought resistance. Six rice cultivars differing in drought resistance were used and subjected to well-watered and water-stressed treatments during their reproductive period. The activities of arginine decarboxylase, S-adenosyl-L-methionine decarboxylase, and spermidine (Spd) synthase in th...

توابع درهم نقش بسیار مهم در سیستم های رمزنگاری و پروتکل های امنیتی دارند. در سیستم های رمزنگاری برای دستیابی به احراز درستی و اصالت داده دو روش مورد استفاده قرار می گیرند که عبارتند از توابع رمزنگاری کلیددار و توابع درهم ساز. توابع درهم ساز، توابعی هستند که هر متن با طول دلخواه را به دنباله ای با طول ثابت تبدیل می کنند. از جمله پرکاربردترین و معروف ترین توابع درهم می توان توابع درهم ساز md4, md...
