项目摘要

This study was carried out to investigate the heterosis for photosynthetic and agronomic charactes, and provide information regarding to cultivation in F_1 hybrid rice produced by crossing a thermo-sensitive genic male sterile (TGMS) T29 line with several indica and japonica cultivers. The (TGMS) T29 line was sterile when exposed to daily mean temperatures of 24.1℃ or above during the stage from 15-11 days before heading. It was completry sterile for both pollen and spikelet when the plant headed from June 16 to November in Okinawa, because the temperature exceeded 24.1℃. The fact indicates that it can be used for F_1 hybrid seed production during this period in Okinawa.Within a temperature range of 20-35℃, photosynthetic ability in term of CO_2 exchange rate (CER) in the F_1 hybrid from the T29 line was lower than the male parent. On the contrary at 40℃, a higher stomatal conductance according to higher transpiration rate was cause of positive heterosis value over both male parent and … More mid-parent for CER in the F_1 hybrid. The higher CER in the F_1 hybrid might be also due to a higher non-photochemical quenching.Heterosis for some physio-morphological characters were investigated in five F_1 hybrids between the TGMS line with indica and japonica cultivars at the active tilllering, flowereing and dough-ripe stages. CER was lower in most F_1 hybrids than in their respective male parent at all stages, mainly due to the lower leaf nitrogen content. During the growing season, a positive heterosis value over the male parent and mid-parent for dry matter production was observed in all F_1 hybrids due to both the larger number of tiller and the larger leaf area per plant. Most F_1 hybrids showed positive heterosis value over the male parent for grain yield and the number of spikelets per panicle. The higher dry matter production at the panicle initiation stage contributed to the heterosis for grain yield in F_1 hybrids. The heterosis for grain yield in the F_1 hybrids also due to the larger number of panicles per plant and especially the larger number of spikelets per panicle.Thus, the effective information regarding to heterosis and cultivation in F_1 hybrid rice produced by crossing a thermo-sensitive genic male sterile (TGMS) T29 line with several indica and japonica cultivers was attained in this studies.

本研究旨在研究光合和农艺性状的杂种优势，并为热敏性雄性不育（TGMS）T29系与几种籼稻和粳稻品种杂交产生的F_1杂交稻的栽培提供信息。 (TGMS)T29品系在抽穗前15-11天期间暴露于日平均温度24.1℃或以上时是不育的。冲绳6月16日至11月开花时，由于气温超过24.1℃，花粉和小穗完全不育。事实表明，该品种可用于冲绳这一时期的F_1杂交制种。在20-35℃温度范围内，T29系F_1杂种的光合能力（以CO_2交换率（CER）计）低于父本。相反，在 40℃ 下，F_1 杂种的 CER 随蒸腾速率升高而产生的气孔导度相对于父本和中亲本均具有正杂种优势值。 F_1杂种较高的CER也可能是由于较高的非光化学淬灭所致。以TGMS系与籼粳品种的5个F_1杂种在分蘖期、开花期和面团成熟期的一些生理形态性状的杂种优势进行了研究。大多数 F_1 杂种的 CER 在所有阶段都低于其各自的父本，这主要是由于叶片氮含量较低。在生长季节，由于分蘖数量较多和单株叶面积较大，所有 F_1 杂种的干物质产量均优于父本和中亲本，具有正的杂种优势值。大多数F_1杂种在籽粒产量和每穗小穗数方面表现出优于父本的正杂种优势值。穗起始阶段较高的干物质产量有助于F_1杂种籽粒产量的杂种优势。 F_1杂种的籽粒产量杂种优势还归因于单株穗数较多，特别是每穗小穗数较多。因此，本研究获得了热敏性雄性不育系（TGMS）T29系与多个籼粳品种杂交产生的F_1杂交稻的杂种优势和栽培的有效信息。较少的
