摘要

本研究在2013-14和2014-15两季进行，共有20个绿绿基因型。旱季土壤月平均含水量为23.46%，夏季为12.95%。所有基因型的形态、生理、生化特性和种子产量均有显著差异。种子产量最高的品种为普萨白萨克(Pusa Baisakhi)，其次为潘月4号、普拉塔普(Pratap)、SGC 25和SGC 20。在单株叶面积、体内叶片硝酸还原酶活性、叶片光合速率、单株总干物质含量和单株荚果数等指标上，浦沙白石基因型表现出最高的水平。另一方面，在夏季，SGC 25基因型的种子产量最高，其次是SGC 20、Pusa Baisakhi、Pant Moong 4和Pratap。单株分枝数、叶片总叶绿素含量、气孔导度、叶片光合速率和单株荚果数均以SGC 25基因型最高。在kharif季节，与夏季相比，种子产量平均高出27.21%。

Analysis of greengram genotypes based on morpho-physiological, biochemical attributes and seed yield in relation to growing season

The study was conducted during kharif and summer seasons of 2013-14 and 2014-15 with twenty genotypes of greengram. The mean monthly soil moisture content was 23.46 per cent for kharif season and 12.95 per cent for summer season. Significant variations in morpho-physiological, biochemical attributes and seed yield were recorded in all the genotypes. The genotype Pusa Baisakhi was found to be the highest seed yielder during kharif season which was followed by Pant Moong 4, Pratap, SGC 25 and SGC 20. The genotype Pusa Baisakhi showed the highest value for leaf area per plant, in vivo leaf nitrate reductase activity, leaf photosynthetic rate, total dry matter content per plant and number of pods per plant. On the other hand, during summer season the genotype SGC 25 was found to be the highest seed yielder followed by SGC 20, Pusa Baisakhi, Pant Moong 4 and Pratap. The genotype SGC 25 was found to record highest value for number of branches per plant, total leaf chlorophyll content, stomatal conductance, leaf photosynthetic rate and number of pods per plant. On an average during kharif season 27.21 per cent higher seed yield could be obtained compared to that of summer season.
