Using UAV to Identify the Optimal Vegetation Index for Yield Prediction of Oil Seed Rape (Brassica napus L.) at the Flowering Stage

Genetic analysis of grain yield, days to flowering and maturity in oilseed rape (Brassica napus L.) using diallel crosses

Twenty one F2 progenies derived from a 7×7 diallel crosses along with parents were evaluated for grain yield, flowering and maturity time. Due to significant genotypic effects for all traits, genetic analyses were performed on F2 progenies including analyses of combining ability and genetic components. The Analysis of variance revealed that both additive and non-additive genetic effects were in...

Leaf Senescence, Root Morphology, and Seed Yield of Winter Oilseed Rape (Brassica napus L.) at Varying Plant Densities

In this study, the yield and yield components were studied using a conventional variety Zhongshuang 11 (ZS 11) and a hybrid variety Zhongyouza 12 (ZYZ 12) at varying plant densities. The increase in plant density led to an initial increase in seed yield and pod numbers per unit area, followed by a decrease. The optimal plant density was 58.5 × 104 plants ha-1 in both ZS 11 and ZYZ 12. The furth...

Genetic study of yield,glucosinolates,oil and protein contents in oilseed rape(brassica napus L.)

Assessment of seed yield stability of spring oilseed rape (Brassica napus L.) promising lines using GGE-biplot analysis

Genotype by environment interaction is one of the complicated issues in plant breeding programs for development of high-yielding with yield stability genotypes. To evaluate seed yield and yield stability of oilseed rape in four southern and northern warm regions of Iran (Zabol, Gorgan, Haji Abad and Sari), nine open pollinated spring oilseed rape lines together with seven cultivars were evaluat...

Researches of Optimum Leaf Area Index Dynamicmodels for Rape(Brassica napus L.)

The objectives of developing optimum leaf area index dynamic models for rape (OLAIDM) was to develop Rape Cultivation Simulation-OptimizationDecision Making System(Rape-CSODS) , to design its planting , to regulate and control its growth and development, and to fulfill its high yield, good quality, high benefits and standard production eventually. The OLAIDM were developed based on field experi...
