Effects of Erect Panicle Genotype and Environment Interactions on Rice Yield and Yield Components
Journal of Integrative Agriculture, 2023 The dense and erect panicle (EP) genotype conferred by DEP1 has been widely used in the breeding of high-yield Chinese japonica rice varieties. However, the breeding value of the EP genotype has rarely been determined at the plant population level ...

Response of the Leaf Photosynthetic Rate to Available Nitrogen in Erect Panicle-Type Rice (Oryza sativa L.) Cultivar, Shennong265 [PDF]
Plant Production Science, 2016 Increasing the yield of rice per unit area is important because of the demand from the growing human population in Asia. A group of varieties called erect panicle-type rice (EP) achieves very high yields under conditions of high nitrogen availability ...

Contribution and Prospect of Erect Panicle Type to Japonica Super Rice
Rice Science, 2021 Over the past 30 years, super rice played an important role in boosting rice yield. The phenotype of erect panicle (EP) architecture controlled by dense and erect panicle 1 (dep1) is the typical characteristic of super rice, and the phenotype has been ...

Identification, pyramid and candidate genes of QTLs for associated traits based on a dense erect panicle rice CSSL-Z749 and five SSSLs, three DSSLs and one TSSL [PDF]
Rice, 2021 Background Seed-set density is an important agronomic trait in rice. However, its genetic mechanism is complex. Chromosome segment substitution lines (CSSLs) are ideal materials for studying complex traits.

Uptake and Utilization of Different Nitrogen Forms in Erect Panicle Japonica Rice Cultivar [PDF]
Journal of Plant Interactions, 2019 The response of rice to nitrogen (N) was compared between three rice cultivars and three N treatments: 1:0, 0:1, and 1:1 NH4+:NO3−. The three rice cultivars used were: Shennong1401 (SN1401, erect panicle rice cultivar) and Habataki and Sasanishiki ...
