| dc.description.abstract | The present investigation on "STANDARDIZATION OF SEED PRODUCTION TECHNOLOGY FOR PIGEONPEA (Cajanus cajan (L.) Millsp.) HYBRIDS" involved the assessment of synchronization of newly developed pigeonpea hybrid, standardization of safe isolation distance for hybrid seed production, study of pollengrain in pigeonpea and determination of the stigma receptivity of 'A' line ofpigeonpea (Cajanus cajan (L.) Millisp). The experiment on four different objective studies were conducted separately. For standardization study the experiment was laidout in a randomized block design with four replication and six treatment. Male parent i.e. ICPR-2671 was sown earlier than female parent ICPA- 2043 by 20 days, 15 days, 10 days, 5 days, on same date and 5 days late than female of hybrid ICPH-2671. There were significant differences for all the characters except flower initiation in male parent. The female parent was early in maturity than male parent by five days. Seed yield (kg/ha) in female line of this treatment was 1728.8 kg/ha which comparatively good as that of other treatments. For standardization of safe isolation distance, experiment was conducted on separate field. The male parent i.e. ICPR-2671 was sown centrally and female parent i.e. ICPA-2043 was sown at a distance of 100 rn, 150m, 200m, 250m, 300m and 350m along with four sides i.e. North, west, south and east directions of male parent ICPR-2671. I)ue to easy insect movement and sunlight toward East outcrossing was more as compared to west direction and minimum outcrossing was observed at 350m distance i.e. 1.53 per cent. The pollegrain studies were carried out of four female line ICPA-2043, ICPA-2047, ICPA-2048 and ICPA-2092. Out ofthese ICPA-2043 line showed maximum sterility i.e. 77.10 per cent and ICPA-2043 showed only 37.43 sterility which was very unstable and ICP A 2092 x ICPR 10650 ยท gives maximum fertility restoration that is 81.30 per cent. The experiment conducted for stigma receptivity of line ICP A-2043 showed that as starvation period to stigma went on increasing, number of pods formed went to decreasing. Number of pods formed upto 10 hours of starvation period of stigma gives good result and upto 34 hour of starvation period, nearly 15 pods are formed out of 20 pollinating buds which was also gives good results. | en_US |
