Capsicum annuum has been known for the amount of variability present in the genus for fruit traits and also for other morphological traits. The present study usedF 1 and F 2 generations developed from diverse parental stocks to report the inheritance pattern for different fruits traits. Our results demonstrate that pepper fruit bearing habit, its colour at unripe stage and fruit apex are simply inherited traits with or without epistatic interactions while fruit length is a quantitative character. Fruit orientation(drooping or erect) and fruit habit (solitary or cluster)showed segregation ratio of 3:1 indicating monogenic inheritance of the trait where drooping character was dominant in nature over erect type and solitary fruit type was dominant over cluster type, fruit bearing habit (single pendant, single erect, cluster pendant and cluster erect) exhibited typical dihybrid ratio of 9:3:3:1, fruit colour at unripe stage (green, purple and mixture of green &amp; purple) segregated in the ratio of 9:3:4 exhibiting recessive gene epistasis and fruit apex (acute or blunt) showed a ratio of 15:1 indicating duplicate dominant gene epistasis. Fruit length exhibited quantitative inheritance with plants showing fruit length greater than the positive parent (parent showing higher fruit length among the two parents) and lesser than the negative parent (parent showing lesser fruit length among the two parents) from different crosses. These results provide new data to clarify and further add on to the information available on the inheritance of chilli pepper fruit attributes. © 2019, Horticulture Society of India.

Inheritance of fruit attributes in chilli pepper

Twenty eight crosses for ten quantitative traits in 8×8 half diallel mating design in brinjal were evaluated in randomized block design with three replications to study heterosis over mid and better parents. Appreciable heterosis was observed over better parent and mid parent for all the characters studied. The lines BBSR 202, BBSR 195-1, BB 26 and BB45C were found superior on the basis of mean performance for earliness and yield related characters. In order of merit, BB 68 × BB 13, BB 13 × BB 44, BB 45C × BB 13, BBSR 202 × BB 13 and BB 26 × BBSR 195-1 showing 69.45%, 66.38%, 40.33%, 35.65% and 31.52% respectively were found to be the five best performing crosses with high heterobeltiosis and mean performance for yield per plant. These cross combinations can be advanced for further testing for commercial exploitation of hybrid vigour. © 2018 Plant Archives. All Rights Reserved.

A field experiment was conducted to study the effect of foliar fertilization of zinc and manganese on growth and yield potential of potato at the experimental farm, School of Agriculture, Lovely Professional University, Phagwara during winter season of 2017- 18. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. There were ten treatments used in which one control and remaining treatment consists combination of zinc and manganese. Growth parameters were recorded at two different intervals viz.: 45 and 60 days after planting and yield parameters were recorded at the time of harvest. Growth parameter were plant height, leaf number while yield parameters were tuber weight, number of tuber, size of tubers per plot and yield were recorded. Quality parameters were protein; protien and TSS were recorded after harvesting. The results showed that the application of (Zinc 10.00 ppm and Manganese 10.00 ppm) showed significant positive impact on plant height, number of tuber, tuber weight and yield of potato. The application of Zinc (10.00 ppm) and Manganese (10.00 ppm) also shows significant impact on quality parameter viz.. protein and TSS. © 2018 Plant Archives. All Rights Reserved.

Chilli or hot pepper is a self pollinated crop but a considerable amount of out crossing is observed in it due to insect activity. In order to know the self pollination behaviour of different chilli genotypes under different growing conditions, a study was undertaken in natural open field, naturally ventilated condition and controlled protected condition to find out whether the growing condition and size of floral reproductive organs affect the rate of pollination (self or cross) or fruit setting in chilli. Natural field growing condition gave maximum fruit set followed by protected condition with fans. Protected conditions however showed least fruit set. The genotypes with less or more stylar length (SL) than filament length (FL) of androecium (SL to FL ratio less than 1 and more than 1.5) showed less fruit setting when compared to genotypes where styles and filaments were almost of same height (SL to FL ratio of 1 to 1.5). This becomes important for chilli improvement program where selfing is to be undertaken and is a component in inbred & population development and varietal maintenance and improvement programs. © 2017, SPR, All Rights Reserved.
