A kind of culture medium for peanut needle cultivation

Abstract

The invention discloses a culture medium used for peanut needle culture, wherein a seedling matrix served as a main raw material is matched up with calcium superphosphate and gels, and the culture medium is prepared by uniformly mixing the calcium superphosphate, the gels and the seedling matrix according to the mass ratio of 1: (4-110): (16-440). According to the culture medium, the problems that pods can not be formed by high peanut needles and the upper peanut needles can not be developed to be full pods can be solved, so that the propagation coefficients of peanut hybrid generation F1 and valuable and rare genetic resources can be improved, and the problem that the pods can not be formed by interspecies cross filial generations due to the fact plants grow flourishingly and the peanut needles are too far away from the ground can be solved.

Description

technical field [0001] The invention relates to the technical field of peanut cultivation, in particular to a culture medium for peanut needle cultivation. Background technique [0002] Peanut is a self-pollinating plant that blooms above ground and bears fruit underground. The ovary stalk can be formed 3 to 6 days after the embryo of peanut is fertilized. The ovary stalk and the ovary at its tip are collectively called fruit needles. The characteristics of ground growth, the fruit needles are buried in the soil for 4 to 6 days, and the ovary expands horizontally in the soil and develops into pods. Under natural conditions, the pods of the same plant have great differences in maturity due to their different insertion positions. Usually, the fruit needles with higher insertion positions cannot be buried in the soil in time because of their distance from the ground, and cannot grow to maturity. Ripe pods lead to ineffective use of some fruit needles. In peanut interspecific ...

Problems solved by technology

Under natural conditions, the pods of the same plant have great differences in maturity due to their different insertion positions. Usually, the fruit needles with higher insertion positions cannot be buried in the soil in time because of their distance from the ground, and cannot grow to maturity. Ripe pods, resulting in the ineffective use of some fruit needles

In peanut interspecific hybrid breeding, interspecific hybrids have low fertility, and the formed fruit needles are easy to abort. The rescue of retired embryos requires high conditions and a large workload, and the success rate is low. On the other hand, the offspring of interspecific hybrids grow Lush, the formed fruit needles cannot enter the soil, and the plant has few pods
