<p>Estimation of Genetic Variability and Correlation Among Early Maturity Mungbean Yield Components. Ratri T. Hapsari. Early maturity mungbean [Vigna radiata (L.) Wilczek] is very important to avoid drought stress, pest and disease attack as well as increase the index planting. The aims of this research was to estimate genetic variability and correlation. The genetic study included heritability, coefficient of genetic variability, genetic advance and correlation among yield components so that it can be used as selection criteria for early maturity mungbean. A total of 145 accessions of mungbean were tested at Muneng farm station in March-June 2010 using a randomized block design, with two replicates. Each accession was planted at 0.8 m x 4 m with spacing 40 cm x 10 cm, with two plants/hole. Fertilization was done by adding 50 kg urea, 75 kg SP36, and 75 kg KCl/ha, at the time of planting. The results showed that mungbean accesions had significant differences in all characters tested. The genetic variance value of all characters was broad with high broadsense heritability estimates, except for number of pods/ cluster and seed number/pod. Genetic advance of all characters were high, except for seed number/pod. The phenotypic correlation between 1000 seeds weight and pod length with seed yield were positive significant while plant height, flowering days, days to maturity, and number of pods per plant had negative significant correlation with its yield. Therefore, plant height, days to maturity, pod lenght, 1000 seeds weight and seed yield could be used as selection criteria based on estimating value of genetic variability, correlation with yield and economic value. There were five genotype which have index value above 20, i.e MLGV 0353, MLGV 0362, MLGV 0354, MLGV 0358, and MLGV 0351.</p><p> </p><p><strong>Abstrak</strong></p><p>Kacang hijau [Vigna radiata (L.) Wilczek] berumur genjah berperan penting untuk menghindari cekaman kekeringan, serangan hama penyakit, dan meningkatkan indeks pertanaman. Penelitian ini bertujuan untuk mengetahui nilai duga parameter genetik dan korelasi antar komponen hasil sehingga dapat digunakan sebagai kriteria seleksi kacang hijau berumur genjah. Sebanyak 145 genotipe kacang hijau diuji di KP Muneng pada bulan Maret sampai dengan Juni 2010 menggunakan Rancangan Acak Kelompok dengan dua ulangan. Setiap aksesi ditanam pada plot 0,8 m x 4 m dengan jarak tanam 40 cm x 10 cm, dua tanaman/lubang. Pemupukan dilakukan dengan 50 kg urea, 75 kg SP36, dan 75 kg KCl per hektar pada saat tanam. Parameter yang diamati adalah tinggi tanaman, umur 50% berbunga, umur 80% masak, jumlah polong/tangkai, jumlah polong/tanaman, panjang polong, jumlah biji/polong, bobot 1.000 biji, dan bobot biji/plot. Hasil penelitian menunjukkan bahwa genotipe yang diuji memiliki keragaman semua sifat yang diamati. Keragaman genetik dan fenotipik tergolong luas. Heritabilitas arti luas tergolong tinggi, kecuali jumlah polong/tangkai dan jumlah biji/polong tergolong sedang. Kemajuan genetik seluruh karakter tinggi, kecuali jumlah biji/polong. Korelasi antara bobot 1.000 biji dan panjang polong bernilai positif nyata dengan bobot biji/plot, sedangkan tinggi tanaman, umur berbunga, umur masak, dan jumlah polong per tanaman berkorelasi negatif nyata. Berdasarkan nilai duga parameter genetik, korelasi antarhasil, dan nilai ekonomisnya, maka tinggi tanaman, umur masak, panjang polong, bobot 1.000 biji dan bobot biji per plot dapat dijadikan kriteria seleksi indeks. Terdapat lima genotipe memiliki nilai indeks lebih dari 20, yaitu MLGV 0353, MLGV 0362, MLGV 0354, MLGV 0358, dan MLGV 0351.</p>

Twenty one crosses resulting from 7 x 7 diallel excluding reciprocal were studied to know the magnitude of heterosis over better parent and standard variety for yield and its attributing characters in rabi mungbean. The highest heterosis to the extent of 37.23% over the check Co-4 and 82.20 % over the check GBM-1 was observed in cross combination Co-4 x Meha for seed yield per plant, which also exhibited high heterosis percentage for yield and yield components. The promising hybrids viz. Co-4 x Meha, Co-4 x GBM-1, GBM-1 x Meha and Rm-9-129 x Co-4 were identified which have great potential to exploit the hybrid vigour or to isolate the desirable segregants for the development of rabi mungbean varieties with chilling tolerant ability or photo-thermo insensitivity, so as to exploit potential of rabi mungbean in heavy rainfall zone as rice fallows.

Waterlogging Condition

Yield performance of 10 selected mungbean (Vigna radiata L. Wilczek) genotypes, viz. GK-7, GK-48, GK-65, VC-6173A, CO-3, IPSA-12, IPSA-13, IPSA-15, BARI Mug-5 and BUmug 2 was evaluated under waterlogged condition in the research field of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh during April to July 2011. Waterlogging depth was 3-5 cm, created by irrigation from tap water and imposed at 22 days after emergence of seedlings which was maintained for 2, 4 and 6 days in the three different treatments. Yield and yield contributing characters of the mungbean genotypes were significantly affected by waterlogging. The longer the waterlogging period, the more was the reduction in seed yield and yield contributing characters. Among the 10 genotypes, IPSA-13 performed the best in respect of grain yield production under waterlogging condition, which was followed by VC-6173A and BUmung 2.The Agriculturists 2017; 15(2) 88-100

Background: Green gram [Vigna radiata (L.) Wilczek] is an ancient and well known pulse crop of Asian countries. Specific traits should be considered for high yield in green gram as selection criteria in future breeding program.Methods: The investigation material comprised of 128 F6 RIL (Recombinant Inbred LINE) population sown at college farm, Professor Jayashankar Telangana State Agricultural University during Rabi-2019-20. The yield and yield attributes were recorded to conduct genetic variability, heritability broad sense (h2), genetic advance (GA) and genetic advance as % of mean (GAM).Result: Analysis of variance revealed significant differences among the RILs, indicating the presence of genetic variability for almost all the traits studied. High PCV and GCV estimates was noticed for number of pods per plant, seed yield per plant, number of cluster per plant and number of pods per cluster. High heritability along with high genetic advance as per cent of mean was observed for number of pods per plant, seed yield per plant, number of cluster per plant, number of pods per cluster, number of branches per plant, number of seeds per pod and plant height indicating the role of additive genes in governing the inheritance of these traits and could be improved through selection. The traits viz. seed yield per plant, number of pods per plant, number of clusters per plant and number of pods per cluster had recorded high PCV, GCV, high heritability along with high genetic advance as per cent of mean indicated these traits were less influenced by environment and possess high genetic variability. Hence these RILs would be suitable for green gram breeding programmes to develop improved varieties. The present findings of the RIL population will be useful for development of high seed yielding variety in green gram.
