“…The Madagascar highlands may have a similar climate to Yunnan where high rice yields are reported (Ying et al, 1998 and also this report) and yield potential there may also be high. However, such high yields seem to exceed the potential yield as simulated by Sheehy et al (2004) in a model which incorporated a physiologically reasonable value of radiation use effi ciency.…”

“…By introducing genes from tropical japonica to indica cultivars, genotypes with almost all these characteristics were bred. However, the yield potentials of NPTs were not signifi cantly higher than the existing cultivars, mainly due to poor grain fi lling (Khush and Peng, 1996;Ying et al, 1998;Horie, 2001). The Japanese Ministry of Agriculture, Forestry and Fisheries (MAFF) initiated super-high yielding rice project in 1981 and released Takanari, an indica-japonica crossbred, in 1990.…”

“…While the Kyoto site (35 o latitude and 20m elevation) had a typical warm temperate climate, the Yunnan site (26 o latitude and 1100m elevation) had a large day-night temperature difference with moderately high solar radiation producing very high yields (Ying et al, 1998). Details of this experiment were described by Horie et al (2003b).…”

“…In the present study, the compensation between panicles per m 2 and spikelets per panicle was not significant for spikelets per m 2 between CTTP and NTDS. An increase in panicle number per unit land area or spikelets per panicle would not necessarily result in an overall increase in the sink size because of a strong compensation mechanism between the two components (Ying et al, 1998).…”

“…Recently, so-called super-rice cultivars or hybrids have been released in China, which have shown a markedly high yield potential when planted in the special areas (Amano et al, 1996;Cheng and Min, 2001). However, these super-rice cultivars or hybrids are commonly characterized by unstable yields across environments (locations and years) (Horie et al, 1997;Ying et al, 1998). Therefore, it is imperative to clarify the responses of their growth and yield formation to environments.…”

Abstract:We characterized yield-relevant characters and their variations over genotypes and environments (locations and years) by examining two rice varieties (9746 and Jinfeng) with high yield potential. 9746 and Jinfeng were planted in two locations of Shanghai, China, during 2005 and2006. The results show that there was a large variation in grain yield between locations and years. The realization of high yield potential for the two types of rice was closely related to the improved sink size, such as more panicles per square meter or grains per panicle. Stem and leaf biomasses were mainly accumulated from tillering stage to heading stage, and showed slow decline during grain filling. Meanwhile, some photosynthetic characters including net photosynthesis rate (P n ), leaf area index (LAI), specific leaf area (SLA), fluorescence parameter (maximum quantum yield of PSII, F v /F m ), chlorophyll content (expressed as SPAD value), as well as nutrient (N, P, K) uptake were also measured to determine their variations over genotypes and environments and their relationships with grain yield. Although there were significant differences between years or locations for most measurements, SLA at tillering and heading stages, F v /F m and LAI at heading stage, stem biomass at heading and maturity stages, and leaf nitrogen concentration at tillering and heading stages remained little changed, indicating their possible applications as selectable characters in breeding programs. It was also found that stem nitrogen accumulation at tillering stage is one of the most important and stable traits for high yield formation.
