A total of 310 lines (BC2F2) derived from the cross of OM5930/N22 were evaluated for heat stress at flowering. Genetic map was set up with 264 polymorphic SSRs to detect linkage to the target traits. The map covers 2,741.63 cM with an average interval of 10.55 cM between marker loci. Markers associated with heat tolerance were located mostly on chromosomes 3, 4, 6, 8 , 10, and 11
The study on rice production and marketing via survey showed that farmers in Mekong had 0.5 ha, 2.2 ha and 6.5 ha for minimum, average and maximum farm size per household, respectively. 100% households carried out their rice production in winter- spring (Dong Xuan-DX) and summer- autumn (He Thu- HT) seasons
The study showed that capacity of rice milling plants ranged from 30 tons to 500 tons per day, average of 170.2 tons/day. There were 20% millers operated over ideal capacity / year, from 130 – 141%. However, almost millers (80%) operated below ideal capacity/year. The paddy inputs among millers were ranged from 6 tons to 500 tons/day, average with 136 tons/day.
SSR genotyping was combined with selective genotyping to map quantitative trait loci (QTLs) associated with drought tolerance in rice. A total of 229lines (BC2F2) derived from the cross of OM1490/WAB880-1-38-18-20-P1-HB was evaluated for drought at flowering (DRF), root dry weight (RDW)
The study conducted from December 2011 to June 2012, the approach is to apply theory ” ValueLinks” (2007) – Eschborn - GTZ (Deutsche Gesellchaft für Technische Zusammenarbeit-Đức) and ”Market for the Poor – Tool of value chain analysis” - M4P (2007).
Study on controlling Ralstonia solanacearum bacterium disease of gourp crop by grafted technicque was conducted in Tra Vinh province anh Ho Chi Minh city from October 2010 to June 2012
Thirty-three potato clones were evaluated for resistance to the common scab disease of potato caused by Streptomyces scabies by artificial inoculation under greenhouse conditions at Dalat.
The heat treatment of recombinantmesophilic cells having heterologous thermophilic enzymes results in the denaturation of indigenousmesophilic enzymes and the elimination of undesired side reactions; therefore, highly selective whole-cell catalysts comparable to purified enzymes can be readily prepared
In this study, a dose-response assessment was performed to understand the relation between supplementation of media with L-ascorbic acid or vitamin C and porcine oocyte maturation and the in vitro development of parthenotes (PA) and handmade cloned (HMC) embryos
288 one day old chicks were collected and randomized in to 6 treatments: T1: control without Diterpen Lacton powder (DLP) and antibiotic; T2, T3, T4, T5: as control plus 0.15, 0.3, 0.45, 0.6% DLD; T6: as control plus 100ppm oxytetracycline + 50ppm tylosine; 12 head/pen, 4 pens/treatment).
