_{step one}P₁ generationsposite interval mapping was used for QTL detection. The window size was set at 5.0 cM and the walk speed at 1.0 cM. Genome-wide significance thresholds were estimated by 1000 permutations to declare significant QTLs with a type-I error rate of 0.05 (Churchill and Doerge, 1994). Finally, QTLs were as presented by WinQTLCart dos.5 (Wang et al., 2012).

Genetic analysis of trend seed products and you can strict-placenta fruit qualities.

Fifteen F₁ individuals, generated by crossing MR-1 with ‘Queen’, showed glossy seeds and untight-placenta fruits. In the BC₁P₁ population, 63 of 134 individuals showed glossy seeds and 71 showed the wave seeds. Sixty-nine of 134 individuals showed untight-placenta fruits and 65 showed the tight-placenta fruits. Segregation ratios were confirmed to be 1:1 by ? 2 test. Wave seeds and tight-placenta plants were never observed in BC₁P₂ population. Furthermore, the 736 plants of the F₂ population segregated into a glossy-to-wave seed/untight-to-tight placenta ratio of 3:1 (Table 1). These results indicated that the wave seed and tight-placenta traits were controlled by two single recessive genes, and these two genes were named ws and tp.
