ABSTRACT
Lack of suitable varieties and genotypes of black gram with adaptation to local conditions is among the factors affecting its production. Efforts to genetically improve the crop mostly involve identifying important morphological descriptors followed by development of advanced breeding lines for locale-specific cultivars. The present day available black gram varieties have not been properly characterized for their thermo sensitiveness with respect to morphological and biochemical characters. Hence efforts were taken in the present research to study the effect of the temperature on these characters in seven black gram varieties over different development stages. We aimed at studying the effect of 3 temperature regimes for identifying suitable stress tolerant genotypes. High percent germination (87.2%), root length (3.68 cm), carbohydrate content (3.72 mg g(-1) fresh tissue) among the genotypes was highest at 10°C-20°C temperature. High shoot length (13.39 cm), free amino acid content (3.73 mg g(-1) fresh tissue), and protein content (9.54 mg g(-1) fresh tissue) was found to be present when the genotypes were exposed to 20°C-30°C temperature. The black gram varieties J.L and PDU-1 performed best in all the temperature regimes over characters. Thus suitable varieties for all temperature regimes were identified using biochemical analysis.

Effect of temperature on germination % of black gram. All the experiments were repeated three times. Each replication consisted of average of 15 seeds per genotype per character per temperature regime, and observations were recorded. Data were recorded on 3rd day and 10th day of germination of seedlings. Analysis of variance (ANOVA) for each character among the genotypes was carried out as per the Student's t-test.

Each replication consisted of average of 15 seeds per genotype per character per temperature regime, and observations were recorded. Data were recorded on 3rd day and 10th day of germination of seedlings. Analysis of variance (ANOVA) for each character among the genotypes was carried out as per the Student's t-test.

Mentions: The genotypes recorded high germination % (Figure 1) on 3rd day (81.85%). Highest shoot length was recorded by T-9 (2.94 cm) and J-L (14.25 cm) on 3rd and 10th day of germination, respectively. J.L recorded the highest root length (Figure 5) on 3rd day (2.2 cm) as well as on 10th day (3.84 cm). The genotypes recorded high mean root length on 10th day (1.75 cm). P.D.U-1 showed the highest fresh weight (1.5 gm) on 10th day while PU-30 recorded the highest fresh weight of 0.94 gm on 3rd day (Figure 2). Genotypes recorded high mean dry weight on 10th day (0.06 gm). O.B.G-17 and J.L recorded the highest amino acid content of 0.95 mg g−1 fresh weight (Figure 7) on 3rd day. The genotypes recorded high mean carbohydrate content (3.72 mg g−1 fresh weight), amino acid content (0.87 mg g−1 fresh weight), and protein content (9.28 mg g−1 fresh weight) on 3rd day.
