Abstract:
Using“0442/3001-18” as female parent and“(025 spring/26×Shanyou162)F
5”as male. parent, the new peanut variety Guihua 36 was obtained by sexual hybridization. Guihua 36 has excellent comprehensive properties, such as high yield, stable yield, high oil, high kernel yield, thin shell, high seed yield and wide adaptability. The average pod and seed yield of Guihua 36 in the na-tional southern regional trial increased by 280.43 kg·hm
-2”and 301.88 kg·hm
-2”,7.35% and 11.53% respectively, compared with the control variety Shanyou 523. The average pod and seed yield of Guihua 36 in the national production trial increased by 394.95 kg·hm
-2”and 391.2 kg·hm
-2,10.55% and 15.12% respectively, compared with the control variety Shanyou 523. Guihua 36 has high yield under pure and intercroping planting patterns. Field experiments confirmed that the high yield of Guihua 36 was closely related to the total number of flowering and the total number of pods per plant, which clarified the high yield mechanism of this variety. The average crude fat content of Guihua 36 was 53.53%. The average protein content of Guihua 36 was 24.71%. Guihua 36 was characterized by 55.6 cm of the main stem height, 63.3 cm of the branch length, 6.9 branches of total branch number, 5.9 branches of effective branch number, 18.7 of pods number per plant, 617 of pods number per kg, 86.7% of full-pod rate, 181.5 g of 100-pod weight, 63.5 g of 100-seed weight, and 71.3% of ker-nel rate.
