Effect of Panicle Size on Grain Yield of IRRI-Released Indica Rice Cultivars in the Wet Season

Influence of Zinc and Iron Fortification on Yield and Post-Harvest Studies of Different Rice Cultivars (Oryza sativa L.)

“…From the result it was observed that biological yield differed due to combined effect of grain yield and straw yield. Variability among different rice varieties for biological yield was also noticed by Laza et al, (2004); Singh et al, (2007); Lack et al, (2012) and Khalifa et al, (2014).…”

“…Superiority of PBNR-03-02 over other varieties indicated that this variety have efficient partitioning for assimilates of photosynthesis from source to sink (panicle). Laza et al, (2004), Singh et al, (2007) and Lack et al, (2012) also reported varietals differences for harvest index.…”

Genetic variation for grain yield, yield components and qualitative traits in rice (Oryza sativa L.) mutants

“…Therefore, this genotype maintained a high grain yield through compensatory effect of having medium number of panicles per plant, number of filled grains per panicle, number of spikelet per panicle, panicle weight and hundred grain weights. LAZA et al, (2004) concluded that rice cultivars with large panicles produced fewer tillers and hence fewer panicles than the cultivar with small panicles. In this regard, having "heavy panicles" or improvement of panicle weight in rice would necessarily lead to increase in grain yield.…”

Genotypic Variations in Responses of Lateral Root Development to Transient Moisture Stresses in Rice Cultivars

“…PSBRc82 (herein referred to as 'irrigatedlowland' genotype) is a high-yielding irrigated-lowland genotype. This genotype was chosen in this study because it consistently produced the highest grain yields among recently released irrigated-lowland cultivars in the Philippines during two wet season evaluations at IRRI (Laza et al, 2004).…”
