Abstract

The intern conducted her research internship by participating in a research project involved in the development of thermosensitive genic male sterile (TGMS) based two-line hybrids at the Crop Science Cluster, UPLB College of Agriculture from August 2008 to April 2009.

The main goal of internship was to identify hybrid combinations that will perform sufficiently better than available inbred and hybrid varieties presently in cultivation. The internship was also conducted to gain experience on actual hybrid rice breeding activities.

The intern performed different major activities in the establishment of hybrid observational nursery like sowing TGMS lines and potential male parents, balling of desired parents of the appropriate stage to make experimental hybrids, laboratory examination of TGMS line of sterility and fertility behavior and post-harvest operations.

Evaluations of experimental hybrids throughout the growing period was the main focus of the research internship. The entries evaluated five check varieties, three recommended inbreds and two hybrids and 200 F1 hybrids that underwent field evaluation for the first time. At the end of growing season, 67 entries were identified as promising based on their yield and phenotypic acceptability. The said entries were eventually advanced into the 2009 dry season preliminary yield trial where evaluation will be more detailed and exhausted
