Thermo-sensitive genic male sterility (TGMS) is an important genetic means of two-line hybrid rice breeding. Pollen fertility in TGMS lines regulated by a single point mutation genes. Based on nucleotide polymorphisms (SNPs) and insertion-deletion mutations, Kompetitive Allele-Specific PCR (KASP) markers were developed utilized molecular breeding via high-throughput detection, which saves time ...

Rice black-streaked dwarf virus (RBSDV) disease is one of the most destructive viral diseases that threatens rice production in China. Breeding resistant cultivars through multi-gene pyramiding considered to be an effective way control disease, but few resistance genes have been characterized date. In present study, we identified T1012, a BC2F6 line from cross japonica variety ‘Wuyujing3’ (reci...

Powdery mildew has a negative impact on wheat production. Novel host resistance increases the diversity of resistance genes and helps to control the disease. In this study, wheat line FG-1 imported from France showed a high level of powdery mildew resistance at both the seedling and adult stages. An F2 population and F2:3 families from the cross FG-1 × Mingxian 169 both fit Mendelian ratios for...

Gene pyramiding is an efficient approach for the genetic improvement of multiple agronomic traits simultaneously. In this study, we pyramided two foreign genes, cry1Ac driven by the rice Actin I promoter, and lysine-rich protein (LRP), driven by the endosperm-specific GLUTELIN1 (GT1) promoter, into the elite indica cultivar 9311. These two genes were chosen in an attempt to enhance insect-resis...

M argin loans have long been associated in the popular mind with instability in security markets. Galbraith (1954) placed them at the center of the 1929 Crash, arguing that heavy borrowing from brokers exacerbated the rise in stock prices in the late 1920s and the stock price declines during the Crash. More recently, the analyses of the U.S. Securities and Exchange Commission (1988) and of the ...

Common bacterial blight (CBB) caused by Xanthomonas campestris pv. phaseoli and X. campestris pv. phaseoli var. fuscans is a seed-borne disease that can signifi cantly reduce yield and seed quality of common bean (Phaseolus vulgaris L.). Disease resistance is the most effective management strategy, but most common bean cultivars have no CBB resistance. Marker-assisted selection (MAS) shows prom...

Bacterial blight caused by Xanthomonas oryzae pv. oryzae and fungal blast caused by Magnaporthe grisea result in heavy production losses in rice, a main staple food for approximately 50% of the world's population. Application of host resistance to these pathogens is the most economical and environment-friendly approach to solve this problem. Quantitative trait loci (QTLs) controlling quantitati...

The brown planthopper (BPH), Nilaparvata lugens Stål, is an insect pest that severely damages rice (Oryza sativa L.) in Asia, causing huge yield loss. Use of resistant variety a cost-effective and eco-friendly strategy for maintaining BPH populations below the economic injury level. However, current have been changed to virulence against varieties. In this study, estimate effective combinations...
