摘要
The degree of photoperiod sensitivity (PS) among the working germplasm accessions varied from 0.63 to 1.00 depending on the extent of delay in flowering during long days in comparison to short days. While a few accessions maintained constant days to flowering in long days, a few others delayed flowering by >30 days in long days in comparison to short days. The accessions were classified into PS, photoperiod insensitive (IPS) and moderately-photoperiod sensitive (MPS). The results suggested independence of degree of photoperiod-induced sensitivity with growth habit, Pod and seed traits. These results are discussed in relation to the strategies for breeding PS/PIS dolichos bean varieties.
