A large set of pigeonpea (Cajanus cajan (L.) Millspaugh) genotypes were screened for their response to photoperiod at ICRISAT. Short duration photoperiod insensitive accessions are very useful in double or multiple cropping systems. This subset contains list of identified photoperiod insensitive accession that are available at ICRISAT Genebank for their utilization in the pigeonpea crop improvement.
Pigeonpea is cultivated in a multitude of production systems, and in a wide range of climatic conditions throughout the tropics and subtropics. Because of its multiple uses as food, fodder and fuel wood; material for thatching and fencing, and for soil improvement and as windbreaks, pigeonpea plays an important role in subsistence agriculture. It is a quantitative short day species and most cultivars flower in day lengths 11 to 11.5 h. The critical photoperiod required to trigger flowering is species-specific and even cultivar-specific. Photoperiod insensitive lines are of particular interest to breeders to develop cultivars for niches and also to ensure synchrony in flowering of parental material for hybrid seed production.
