“…This suggested that the PFG in YD was more stable and superior to that in the Japanese cultivar HH in spite of its larger sink size. PEG in Chinese F 1 hybrid rice cultivars with larger NS-P have been reported to decrease less with increasing NS-m 2 (Song et al, 1990;Amano et al, 1996).…”

“…On the other hand, large-panicle rice cultivars including not only F 1 hybrids but also normal inbred cultivars with 150-200 spikelets panicle -1 have been bred in China in recent years and have contributed to yield increment (Song et al, 1990;Ikehashi, 1994a, 1994b;Wang et al, 1995Wang et al, , 1997Amano et al, 1993Amano et al, , 1996Katsura et al, 2007). The 1000-grain weight is also higher in these large-panicle-type cultivars than in the Japanese cultivars and tends to increase (Yamamoto et al, 2001).…”

“…However, most of these studies analyzed only the cultivar differences in yielding ability under limited cultivation conditions (Takeda et al, 1984;Song et al, 1990;Saitoh et al, 1991Saitoh et al, , 1993Wang et al, 1991;Yamamoto et al, 1991;Amano et al, 1993Amano et al, , 1996Kusutani et al, 1993;Miah et al, 1996;Shiotsu et al, 2006;Katsura et al, 2007), and few reports are available on the effects of a wide range of cultivation practices on the yielding ability (Weng et al, 1982;Komatsu et al, 1984;Kubota et al, 1988;Sumi et al, 1996). Analysis of the effects of cultivation practices on the yielding ability in relation to sink size and PFG might reveal practical information on high-yielding cultivation of these large-panicle-type cultivars.…”

“…Super rice, developed with the combine efforts of International Rice Research Institute (IRRI) and other Asian countries like China, Korea and Japan, has gained much importance due to its high yield potential (Amano et al 1996). China has already established mega-projects on its multiplication and development to encounter the food challenges in future.…”

Recently, super rice has gained much importance due to its high yield potential while exogenous application of plant growth regulators (PGRs) is an important aspect in plant development and defense responses under stress conditions. In this study we conducted two pot experiments. Firstly, four super rice cultivars, viz. Peizataifeng, Huayou 213, Yuxiangyouzhan and Huahang 31 were subjected to a series of five chilling temperatures, i.e. 11 °C, 12 °C, 13 °C, 14 °C and 15 °C (day/night) for about 25-27 days. Secondly, seeds of Peizataifeng (super rice) and Yuejingsimiao 2 (non-super rice) were then treated with different combinations of salicylic acid (SA), brassinolide (BR), calcium chloride (CaCl 2 ) and fulvic acid (FA) and then exposed to chilling stress at 13 °C for four days. Resultantly, Peizataifen (super rice) was found with the lowest seedling survival rate at all chilling temperatures among all four super rice cultivars, however, it was still found more resistant when compared with Yuejingsimiao 2 (non-super rice) in the second experiment. Furthermore synergistic effect of all PGRs alleviated low temperature stress in both rice cultivars by improving seedling survival rates, leaf area, seedling dry weight, seedling height, root morphology and by modulating antioxidant enzymes, improving proline content and lowering lipid peroxidation.

“…Hence, the world rice production must increase by approximately 1% annually to meet the growing demand (Rosegrant et al, 1995). 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).…”

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.
