Summary Triple test cross-analysis was used to detect epistasis in chickpea. None of the characters investigated exhibited epistasis. In the absence of epistasis, additive and dominance effects were estimated. The results indicated the importance of additive genetic variance for seed yield, biological yield, number of primary branches, number of secondary branches, 100-seed weight, days to flower, and number of seeds per pod; dominance genetic variance for days to mature; and both additive and dominance genetic variances for plant height. Selection methods, such as pedigree and bulk, are suggested for the improvement of most characters.Joint contribution from ICARDA, P.O.

In the visual inspection systems of PCB line detection, a good preprocess effect of test image is the precondition of the system with fine performance, while the its speed is the determinant of the real-time inspection performance. This paper proposed a preprocess algorithms of PCB test image, which includes two parts-binarization and denoising. The experiment shows that the preprocess algorithm is able to obtain an effective threshold for the binarization of the defect image, eliminating the noise and enhancing the speed highly. 相似文献
