This study reports the development of a garden pea genotype `VRPM±901±5' producing
five flowers per peduncle at multiple flowering nodes, by using single plant selection
approach from a cross `VL-8 × PC-531'. In addition, five other stable genetic stocks, namely
VRPM-501, VRPM±502, VRPM±503, VRPM±901±3 and VRPSeL±1 producing three flowers
per peduncle at multiple flowering nodes were also developed. All these unique genotypes
were of either mid- or late- maturity groups. Furthermore, these multi-flowering
genotypes were identified during later generations (F4 onward), which might be because of
fixation of certain QTLs or recessive gene combinations. Surprisingly, a common parent
PC±531, imparting multi-flowering trait in ten cross combinations was identified. Thus, the
genotype PC±531 seems to harbor some recessive gene(s) or QTLs that in certain combination(
s) express the multi-flowering trait. The interaction between genotype and environment
showed that temperature (11±20ÊC) plays a key role in expression of the multiflowering
trait besides genetic background. Furthermore, the possible relationship between
various multi-flowering regulatory genes such as FN, FNA, NEPTUNE, SN, DNE, HR and
environmental factors was also explored, and a comprehensive model explaining the multiflowering
trait in garden pea is proposed.
