Abstract

為配合一年一期稻作，改變本省作物輸作制度之需，於氣溫較高的夏季，在全省八個地點，測驗8個秈稻雜種品系中間作之稻穀產量及適應性。參試品系在各地之稻穀產量差異極大。臺秈雜育5、6、10號等三品系的全省平均產量較高，比對照品種臺中秈10號增產8.2～3.2％。在北部二處臺秈雜育10號產量達6.8～6.9t/ha，增產幅度有16～28％，顯示上述構想在北部是可行的。臺秈雜育1、7、11號等三品系因具有感光性，受夏季長日影響而零星抽穗，產量偏低；但在嘉義（鹿草）因蟲害嚴重改採宿根栽培，延至11月上旬收擭，其產量奇高，最高達8.5t/ha，遠高於對照品種。然在嘉義分所另一處（溪口）卻因病蟲害嚴重而致廢耕。此等結果顯示單交雜種品系的特殊組合力因環境而有很大之差異，在適當環境下有可能發揮高產之潛力。如何利用其特殊組合力或感光性使雜種優勢能發揮其最高之潛力，將是下一步的試驗目的。 To explore a single rice crop a year to fit into the rotational system with other crops, 8 Indica hybrid rice strains were tested for their yield potentials and adaptabilities at 8 locations in between the first and second crop seasons when temperatures were high. Their grain yields varied greatiy with the entries and locations. In an overall average, Tainung Sen Hybrid 5, 6 and 10 outyielded the highest yielder, Taichung Sen 10, only by 3.3%－8.2%. However, the yield of Tainung Hybrid 10 at the northern 2 sites reached 6.8t/ha-6.9t/ha or 16%-28% higher than the control, indicating the acceptability of the above-mentioned planting. On the other hand, Tainung Sen Hybrid 1, 7, 11 performed poorly due to their photoperiod sensitivity. At Chiayi (Lutsau), the insect infestation was so severe that the testing plants had to be ratoon-cultured and harvested in November with a yield as higher as 8.5t/ha. The test at another location in Chiayi (Chikou) was completely failed due to the severe insect damage. The single cross hybrids like these generally have a poor general combining ability but show various special combining abilities depending upon varieties and the environments. To explore the possibility of utilizing their special cominbing ability and photoperiod sensitivity to allow the full expression of high yield potential due to hybrid vigor will be our next step of experiments.
