การถ่ายทอดลักษณะพันธุกรรมของปริมาณแป้งในเมล็ดถั่วเขียว [Vigna radiata (L.) Wilczek] / ศุภฤกษ์ กุลปภังกร = An inheritance of starch content in seeds of mung bean [Vigna radiata (L.) Wilczek]
Twenty mung bean lines were grown to select for pure lines of which 17 of them were chemically analysed for percentage of starch content. Direct and reciprocal crosses were made between the highest and lowest starch content lines (VC 2755-54 and VC 2742-26-35) to produce F1 and F1R seeds. F2 and F2R seeds were obtained by allowing the F1 and F1R plants to self pollinate. The parental lines (p1and p2) and their respective F1, F1R, F2 and F2 R families were grown in a completely randomized design manner. Heritability of starch contents percentage, yield per plant, number of seeds per pod, number of pods per plant and 1,000 seeds weight were studied. Correlation between starch content and the other characters was also studies within each generation. The result revealed that variation among generations was highly significant (p = 0.01) in all traits, except in number of pods per plant. The average of broad sense heritability estimates of starch content, yield per plant, number of seeds per pod and 1,000 seeds weight were 52.82, 57.99, 26.76 and 34.88%, respectively. The correlation between starch content with 1,000 seeds weight was positive and significant in all generations studied. However, no correlation with other traits was detected.
