Abstract: The standard seedbox screening technique (SSST) was unsuitable to evaluate the resistance of the interspecific somatic rice hybrids to N. lugens. A tiller seedbox screening technique (TSST) was therefore established, which was different from SSST as follows: 1) instead of the seeds, the tillers, about 25 cm high, of the regenerated plants and the checks (IR26, ASD7, TN1) were planted in a seedbox; 2) the plants were infested with 1- to 3-day-old adults rather than the nymphs of N. lugens (0.2 female per tiller, female:male=1:1.2-1.5) when the plants survived. The results showed that TSST is suitable for evaluating the resistance of the interspecific somatic rice hybrids to N. lugens.
