Abstract: The present investigations entitled "Effect of planting seasons on stigma receptivity and pollen viability in parental lines of bajara Pennisetum glaucum (L.) R. Br.) was under taken to obtain the information on stigrna receptivity and pollen viability in parental lines of hybrid bajara. The work was carried out at Research Farm, Post Graduate Institute, Department of Botany, Mahatma Phule Krishi Vidyapeeth, Rahuri. The experiment was laid out in a7" Randomised Block Design ÜRBD) with 4 replications in kharif 2001 and summer 2002. The experimental material consists of two male sterile lines viz., RHRB 1A and RHRB 5A and their maintainers. The observations recorded were days to initiation, 50 per cent and complete anthesis, days to stigma protrusion, 50 per cent flowering and maturity, seed setting percentage, number of seeds per earhead, seed weight per earhead and 100 seed weight. Pollen viability studies was carried out by using acetocarmine test. For stigma receptivity, both male sterile lines showed highest seed setting percentage at zero day of starvation period during kharif and summer season. Number of seeds per earhead, seed weight per earhead and 100 seed weight decreased at each successive starvation period. It can be revealed that stigmas were receptive for 2 days for both male sterile lines during kharif and summer season. For pollen viability during both seasons, male sterile lines RHRB-1A and RHRB-5A showed highest seed setting percentage at zero hour of pollination period which was followed by 2 hours of pollination period. Number of seeds per earhead, seed weight per earhead and 100 seed weight decreased at each successive pollination period. It was revealed that the pollens of both maintainer lines RHRB- 1A and RHRB-5B remained viable for 4 hours after collection during both the seasons.
