Comments Trait assyed for Rubisco to total leaf nitrogen content. Total leaf nitrogen content was determined by CN-Corder (Yanaco Co. Japan) by using the leaf samples oven-dried at 80C for 3 days. For determining Rubisco content soluble proteins (2 µg) were subjected to SDS-PAGE using 12.5% (w/v) gels containing 0.1% (w/v) SDS, and the gels were stained with Coomassie brilliant blue. The intensity of the band corresponding to Rubisco was measured with an image analyzer (Umax Technologies, Calif.). The analysis was done on contents derived from leaf tissue collected 5 days after heading. The means of ten replications per line were used in the data analysis. Phenotypic effect contributed by Nipponbare allele. Chromosomal locations of putative QTLs were determined by single-factor analysis (one-way ANOVA) with the general linear model procedure of QGENE. A probability level of 0.01 was used as the threshold for detecting significant differences at P < 0.005 in the mean values of the two genotypic classes, homozygous for Nipponbare and Kasalath alleles. In the back crossed inbred lines (BILs) there was a high correlation among the soluble protein content and Rubisco content at 5 days (r=0.554; P<0.01) after heading.
