Growth and Yield of Promising Rice Entries Under Cool, Elevated Condition

Abstract

The study aimed to evaluate and compare the growth and yield performance of the different rice entries and to determine which entry is more adapted and suitable under coolelevated areas like La Trinidad, Benguet. The fourteen entries evaluated were Ketnel (Local check), IR81551-2-1-3-3-2-PR, PR34126-B-10, NSIC Rc 104, IR82187-17-3-2-1-2, PR34110-B-4-3-1, IR81528- 15- 3-22-PR, PR34131-B-21-1, PR34126- B-2, IR82737-B-B-B-B-182, PSBRC 46, IR83140- B- 11- B, PR34131-B-20-1 and IR83140-B-28-B. Results showed that NSIC Rc 104 and PSBRc 46 had good growth performance and yield. These varieties showed significant differences on rate of recovery, tiller number, number of productive tillers per hill, length of panicle, number of grains per panicle, number of filled grains per panicle, grain yield per plot, weight of 1000 grains and computed grain yield per hectare. In addition, all entries need further evaluation for more a stable result under cool, elevated condition and within other seasons.
