Optimizing Hill Seeding Density for High-Yielding Hybrid Rice in a Single Rice Cropping System in South China
Mechanical hill direct seeding of hybrid rice could be the way to solve the problems of high seeding rates and uneven plant establishment now faced in direct seeded rice; however, it is not clear what the optimum hill seeding density should be for high-yielding hybrid rice in the single-season rice production system. Experiments were conducted in 2010 and 2011 to determine the effects of hill s...
متن کاملVariations in DENSE AND ERECT PANICLE 1 (DEP1) contribute to the diversity of the panicle trait in high-yielding japonica rice varieties in northern China
Rice is one of mankind's major food staples, and the erect panicle architecture in rice is an important morphological improvement. The dense and erect panicle 1 (DEP1) locus corresponds with the formation of erect panicles and has been widely used in rice breeding. However, the genetic diversity of DEP1 remains narrow. In order to improve the genetic diversity of DEP1, we used a rice germplasm ...
متن کاملThe DENSE AND ERECT PANICLE 1 (DEP1) gene offering the potential in the breeding of high-yielding rice
The erect panicle model super-rice can rationally transform the solar energy into accumulated organic matter (biomass) and increase grain yield. The phenotype of erect panicle architecture controlled by DENSE AND ERECT PANICLE 1 (DEP1) has been used in rice breeding for nearly a century owing to its high-yield, lodging tolerance with strong stem, reasonable population structure and high nitroge...
متن کاملHigh Potential of a Transposon mPing as a Marker System in japonica × japonica Cross in Rice
Although quantitative traits loci (QTL) analysis has been widely performed to isolate agronomically important genes, it has been difficult to obtain molecular markers between individuals with similar phenotypes (assortative mating). Recently, the miniature inverted-repeat transposable element mPing was shown to be active in the japonica strain Gimbozu EG4 where it had accumulated more than 1000...
متن کاملHigh yielding and moderately resistant to fruit rot disease chilli hybrid – CCH 1 ( TNAU Chilli Hybrid CO 1 )
Anthracnose is one of the serious diseases in chilli which affects whole plant and also fruits in particular. A study was undertaken to develop a high yielding and anthracnose disease resistant hybrid in chilli at the Dept. of Vegetable Crops, HC & RI, TNAU, Coimbatore during 2004-05. As a first step, ninety three germplasm lines maintained in the Dept. of Vegetable crops were evaluated for dis...
