in order to determine combining ability, heritability and heterosis of some agronomic traits in rice, 4 pure lines were crossed with 2 cytoplasmic male sterile testers. parents and their f1 progenies arranged in rcb design with three replications. analysis of variance showed significant differences among genotypes for all traits, except for filled grains/panicle. furthermore, the crosses effect...

This study aims to provide information on the effective and efficient provision of rice husk biochar betel nut for growth production crops in tidal marshlands. The research was carried out community fields located Pembengis Village, Bram Itam District, Tanjung Jabung Barat Regency, Jambi Province with a height 3 meters above sea level (masl). used Randomized Group Design (RAK) two factors, firs...

Panicle caterpillars comprise an economically important insect pest complex of sorghum throughout the Great Plains of the United States, particularly in Kansas, Oklahoma, and Texas. The sorghum panicle caterpillar complex consists of larvae of two polyphagous lepidopteran species: the corn earworm, Helicoverpa zea (Boddie), and fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noc...

Aphelenchoides besseyi is a seed-borne plant parasitic nematode and is widely distributed in most rice growing areas. Application of resistant cultivars requires the identification of resistance source, which can then be included in breeding programs to improve the local rice cultivars. Fourteen Iranian rice genotypes including improved and local varieties were evaluated for resistance to A. be...

Before selecting genotypes for nutritional quality characters (protein, oil and micronutrients content) and anti-nutritional factor (phytic acid), it is important to know how much selection is likely to affect yield. Using a diverse range of genotypes, relationships between quality traits with yield and yield attributes in pearl millet were investigated. The number of productive tillers, panicl...

Effective panicle number, grain number, and grain weight are the three components of rice yield, of which grain number shows the highest variation and makes the largest contribution to yield output.Rice panicle number per plant is a grain yield component that directly influences rice yield. The identification of the genes controlling panicle number will play a vital role in high-yield rice bree...
