QTL Analysis of Seed Longevity.
(A) Loss of viability during storage at 75% RH, 35°C of both parents (J6 and DZA 315.16) using triplicates of 30 to 50 seeds obtained from three to five plants. Data (means ± se) were fitted with sigmoidal curves.
(B) Frequency distribution of percentages of germination and normal seedlings after storage obtained from the LR4 RILs. Time and conditions of storage are indicated together with the value obtained from the respective parents.
(C) Genetic map of linkage group 7 showing the QTL mapping for time to 50% germination (T50), sugar content, and viability after indicated storage times and conditions from seeds produced in Angers and Dijon (France). The lines indicate the confidence intervals and the peak positions.
