To investigate the newly developed lines of peanut during different mature stages with peanut combine harvester, the trials were conducted at Ta-Chen Hsiang during sprng crop on 2000. Two newly developed lines and two check varieties were investigated at three maturing stages treatments those were R7, R8 and R9 with combine harvester.At R7 period, the results showed that the yields of fresh pod and dry pod of Taichung-yu No.1 were 10,246 kg/ha and 3,070 kg/ha, respectively. And the ratio of thresh pods is 99%, the ratio of unthreshed ovary pedicle is 4.0% and the broken pods percentage is 0.3%. The yield of fresh pod and dry pod of Taichung-yu No.2 were 10,465 kg/ha and 3,283 kg/ha, respectively. And the ratio of thresh pods is 99%, the ratio of unthreshed ovary pedicle is 3.3% and the broken pods percentage is0.5%. The check local variety Li-chi-tze (CK1) showed 8,823 kg/ha and 2,808 kg/ha in yield of fresh pod and dry pod, respectively. And for the other three characteristics were 95%, 2.4%, 0.4%. The other check variety Tainan No.11 (CK2) showed 5,350 kg/ha and 2,275 kg/ha in yield of fresh pod and dry pod , respectively. And for the other three characteristics were 99%, 3.0%, 0.3%. During R8 stage, the yields of fresh pod and dry pod of Taichung-yu No.1 were 11,281 kg/ha and 4,962 kg/ha, respectively. And the ratio of thresh pods is 97%, the ratio of unthreshed ovary pedicle is 9.1% and the broken pods percentage is0.5%. The yield of fresh pod and dry pod of Taichung-yu No.2 were 10,447 kg/ha and 5,074 kg/ha, respectively. And the ratio of thresh pods is 98%, the ratio of unthreshed ovary pedicle is 10.6% and the broken pods percentage is 1.5%. Local variety Li-chi-tze showed 10,044 kg/ha and 4,536 kg/ha in yield of fresh pod and dry pod , respectively. And for the other three characteristics were 96%, 9.8%, 1.6%. Tainan No.11 showed 7,503kg/ha and 3,998 kg/ha in yields of fresh pod and dry pod , respectively. And for the other three characteristics were 97%, 9.1%, 1.2%. While the last R9 stage, the yields of fresh pod and dry pod of Taichung-yu No.1 were 7,749 kg/ha and 4,864 kg/ha, respectively. And the ratio of thresh pods is 96%, the ratio of unthreshed ovary pedicle is 9.8% and the broken pods percentage isl.6%. The yield of fresh pod and dry pod of Taichungyu No.2 were 7,237 kg/ha and 4,358kg/ha, respectively. And the ratio of thresh pods is 98%, the ratio of unthreshed ovary pedicle is 10.4% and the broken pods percentage is 1.5%. Local variety Li-chi-tze showed 7,727 kg/ha and 4,217 kg/ha in yields of fresh pod and dry pod , respectively. And for the other three characteristics were 98%, 11.3%, 0.4%. Tainan No.11 showed 5,077 kg/ha and 3,291 kg/ha in yields of fresh pod and dry pod , respectively. And for the other three characteristics were 95%, 7.4%, 0.5%. The results of two newly developed lines harvest by peanut combine during three mature stage showed higher ratios in unthreshed ovary pedicle than the check variety Tainan No.11.
