| ：【Objective】Two cultivars of pea (Pisum sativum L.), Cv 13 (with red flowers, purple pods and high stalk)
and Cv 4 (with white flowers, green pods and dwarf), were used as parents to breed new dwarf varieties of pea with red flowers
and purple pods, suitable to be cultivated in Guangdong with ornamental and edible values. 【Method】With Cv 13 and Cv 4
as parents, the F1 generation was obtained through reciprocal crosses. After being replanted, a new dwarf variety with red flowers
and purple pods was screened out from F2 hybrids with 3 traits of red flower, purple pod and dwarf stalk as breeding objectives.
【Result】During the process of variety selection, it was found that high stalk showed dominant character compared to dwarf
stalk, which is in accordance with segregation law of Mendel’s genetic law. Pod color was related to flower color, of which red
flower and white flower corresponded to purple pod and green pod, respectively, and it was controlled by quality traits. Two new
dwarf varieties of with red flowers and purple pods were obtained through the selection of F2 hybrids and named as No. 1 and
No. 2. Based on the analysis on relevant phenotype and quality, No. 1 had a plant height of 94.00 cm with red flower and purple
pod and the relative content of anthocyanin was 0.65, while No. 2 had a plant height of 90.00 cm with red flower and purple
pod and the relative content of anthocyanin was 0.34. 【Conclusion】 Both No. 1 and No. 2 are new varieties of dwarf pea with
red flowers and purple pods, which have high ornamental and edible values. No. 1 has relatively high anthocyanin content and
higher nutritional value. |
