Rice improvement breeding is one of the most important research fields in China. With the development of modern rice breeding technology, hundreds to thousands of new varieties are produced daily, creating the impetus for rapid plant phenotyping evaluation. However, traditional measurement is inefficiency, contact-interferential, and lack-objectivity. Thus a high-throughput and automatic extrac...

Italian rice production is progressively threatened by water scarcity. Some strategies have been developed to reduce water use. Nevertheless, reducing water irrigation amounts may lower paddy rice production. This publication compares the productivity and the economic performances of traditional and modern rice varieties in northern Italy using two different water management systems. The object...

Red rice is a troublesome weed in rice-growing areas of the southern U.S. Red rice in Arkansas may be diverse enough to warrant some adjustments in weed control programs. A study was conducted at the Rice Research and Extension Center (RREC), Stuttgart, Ark., in 2003 to determine the phenotypic diversity of red rice in Arkansas. One hundred thirty-six red rice accessions were collected from 26 ...

Chitosan was modified with sodium hydroxide and polymerized in water with plant growth regulators, microfertilizer and other additives to give a novel environmentally friendly seed coating agent for rice. The results showed the seed coating agent has obvious biological effect through the germination test, bacteriostasis test, toxicological security test and field experiment. Compared with the t...

Background: Arsenic and heavy metals are implicated in causation of CKDu among farmers in dry zone of Sri Lanka. Rice has been identified as a major source of arsenic in research carried out in other countries. We analyzed 120 samples of new improved varieties (NIVs) and 50 samples of traditional varieties (TV) of rice for total arsenic content. Findings: Rice cultivated in Sri Lanka is contami...

Parachute transplanting method of rice as compared to line transplanting and farmer’s method of random transplanting was studied at 10 different locations viz., Kamonki, Wazirabad, Daska, Pasroor, Gujranwala, Sialkot, Lahore, Hafizabad and Sheikhupura during 2003 and 2004. Super Basmati was used as test variety. Yield and yield components of three transplanting techniques, averaged across 10 lo...

Even as the study of plant genomics rapidly develops through the use of high-throughput sequencing techniques, traditional plant phenotyping lags far behind. Here we develop a high-throughput rice phenotyping facility (HRPF) to monitor 13 traditional agronomic traits and 2 newly defined traits during the rice growth period. Using genome-wide association studies (GWAS) of the 15 traits, we ident...

introduction of high yielding as well as high quality rice cultivars is one of the most important activities at rice research institute of iran (rrii). in 1991, 210 rice lines introduced from international rice research institute (irri) to rice research institute of iran were evaluated in observational and statistical experiments in mazandaran for two years, and seven lines were selected. these...

Blast, Pyricularia grisea (Cooke) Sacc., is one of the most destructive diseases of rice worldwide and canresult in significant reductions in yield. The use of resistant cultivars is the most economical and effectiveway of controlling rice blast. A variety of DNA markers, including plant defense-related candidategene markers are available for genetic characterization and molec...
