| Investigation was made of growth and yield rice in response to different environments of irrigated rice varieties in paddy field at Klong Luang Rice Research Center during 2012 to 2013. The objective of this research was to correlate the effect of climate change on growth and rice yield. Five non-photoperiod sensitive rice varieties (Suphanburi 1, Suphanburi 2, Pathumtani 1, RD 29 and RD 43) were varied planting date. The results showed that 1) Increasing of the mean temperature, rain, humidity, wind speedy and the cumulative of sunshine per day will tend increasing height and number tiller of rice during sowing date to tillering stage. 2) Low temperature and lese of the cumulative amount of sunshine per day effect to the ripening stage was shorter... |

| The selection of eri silkworm ecorace with high yield and distinct in morphological character is necessary for variety improvement. Five eri silkworm ecoraces, SaKKU1, SaKKU2, SaKKU3, SaKKU4 and SaKKU5 were surveyed and derived in country or from academic cooperation in international level. All ecoraces were cultured using castor leaves of TCO101 variety as food plant at 25±2 °C, 80±5%R.H. Based on morphological characters, there were similar except body of the 5th instar larva of SaKKU1 was covered with white powder and ripe larva showing shiny dominant yellow color. Life cycles were also similar durations, 46-53 days (SaKKU1), 42-53 days (SaKKU2), 42-52 days (SaKKU3), 40-56 days (SaKKU4) and 41-52 days (SaKKU5). SaKKU1 had highest survival rate at larval... |
