The Correlation Between Main Agronomic Traits and Yield Per Plant in Transferred Intergeneric Material Rice in Dry Conditions
TANG Yong-Qun, LI Jing-Yong, ZHANG Xian-Wei, YAO Xiong
Abstract: The experiment results show that in dry conditions, the rice is transferred between the different intergeneric materials, including the descendants of the different recipient parent, single plant grain yield and agronomic traits is closely related to the plant effectively panicle number, panicle length, number of secondary branches per panicle grain number，seed setting rate and grains per panicle related to effective yield per plant is also greater; the results of direct assessment and selection of field drought resistance materials provided. Key words: dry conditions；the material rice which is transferred between the intergeneric material；agronomic traits；yield per plant；correlation

Large Adjustment Technology of Non-synchronous Flowering of Hybrid Seed Production
HUANG Yuan-Wen
Abstract: Synchronous flowering is the key to determine whether the success of hybrid seed production can be achieved. Once the flowering deviation is above 10d, applying large adjustment technology can ensure the synchronous flowering. Key words: hybrid rice;seed production; non-synchronous flowering; large adjustment technology

Effects of Different Sprayers and Spraying Methods on Controlling Rice Leaf Roller
CHEN Lin- Sheng
Abstract: Effects of four different sprayers and spraying methods on controlling rice leaf roller were studied at Changting County in 2010. The results showed that, 3WF-950 backpack sprayer not only saved time and labor, but its effect of controlling rice leaf roller was significantly higher than that of 20-type electric sprayer or 3W8S-16-type hand sprayer, suggesting this sprayer should be popularized in plant protection machineries. The control effect of 3WH-36 stretcher-style sprayer was slightly lower than that of 3WF-950 backpack sprayer, but its spraying efficiency was significantly higher than the latter. 3WH-36 stretcher-style sprayer can be recommended as plant protection machinery in carrying out large-scale control of rice leaf roller.
