Abstract

An investigation was carried out in the university farm for 10 genotypes of lathyrus species to find out the best genotypes(s) which may be grown in this terai region of West Bengal. Characterization and evaluation genotypes were done according to DUS descriptors developed by International Plant Genetic Resources Institute, Rome, Italy (IPGRI 2000). From the statistical analysis by CRBD, the results of genotypes like BK-7-1 was found to have maximum plant height, leaf length, pods per plant, pod length, seeds per pod, yield per plant, biological yield per plant, and biological yield per plot. WBK-10, BK-2, BK-27-1, BK-7-1 yield per plot, and high seed index were found in WBK-10, Bidhan-2, BK-2 along with BK-7-1. Seeds per plant were found highest in WBK-10. In seeds per pod, maximum was found in BK-27-1. Pods per plant were also found highest in BK-7-1. Challenges of the study is indeterminate habit of the plant where collection of data should be very carefully done starting from first

Conclusion

BK-7-1 was found to have maximum plant height, leaf length, pods per plant, pod length, seeds per pod, yield per plant, biological yield per plant, and biological yield per plot followed by WBK-10, BK-2, and Bidhan-2, BK-27-1 where they performed good in biological yield per plot. WBK-10, BK-2, BK-27-1, BK-7-1 yield per plot, and high seed index were found in WBK-10, Bidhan-2, BK-2 along with BK-7-1. Seeds per plant were found highest in WBK-10 followed by BK-7-1, Berhampur local and BK-2. In seeds per pod, maximum was found in BK-27-1 followed by Bidhan-1, BK-2, Kaikhali local, and Berhampur Local. Pods per plant was found highest in BK-7-1 followed by WBK-10, BK-2, and Berhampur Local were found in yield-related characters along with biological yield. So, BK-7-1 is the best genotype, followed by BK-2, BK-27-1, WBK-10, Bidhan-2, Kaikhali local and Berhampur Local can be selected considering all the yield attributes of this investigation.
