we came across two genotypes of T. durum where the arrangement of spikelets in the spike were irregular, as some spikelets tilted towards one side whereas others get angled in opposite direction. The

Pigeonpea [Cajanus cajan (L.) Millspaugh] is a partially
out-crossed species and on average, the insect-aided
natural out-crossing varies around 25-30% [1]. The
pigeonpea breeders have used crop improvement
procedures relevant to both self as well as cross
pollination mechanisms. Since, hybridization is an
integral part of genetic enhancement programmes, an
adequate knowledge of pollination behaviour helps in
deciding mating schemes. In pigeonpea, where hybrid
breeding technology has been developed [2] , the
duration of stigma receptivity of female parent plays an
important role in enhancing the quantities in insect-aided
seed production of hybrids and their parents. Therefore,
a study was undertaken at ICRISAT to understand the
stigma receptivity pattern in pigeonpea.
