Analysis of the productive structure and yield behavior of four rice varieties (Oryza sativa L.) from different origins in Ibaraki prefecture, Japan
Main Article Content
Abstract
Experimental Plot (RE1) from Tsukuba International Center
(TBIC) located in Ibaraki Prefecture, Japan, with the objective
of analyzing the productive structure and yield of four rice
(Oryza sativa L.) varieties of different origin. Treatments
correspond to J-104, Bluebonnet-50, Suweon-294 and
Nipponbare varieties. Dry matter content and light intensity
were determined, also yield and its components were evaluated
and the relationship existing between yield and light intensity
was analyzed. A Single Classification Variance Analysis and
Duncan�??s Multiple Range Test were used. Results showed
differences between treatments and the indica-japonica variety
Suweon-294 presented the best behaviour in the productive
structure analysis, while the indica variety J-104 reached the
highest yields. The regression between studied variables
indicates a direct relationship.
